SketchUp tips

Hold down CTRL while moving geometry to do a copy.

With the Select tool, if you drag left to right, you will select every-thing inside the window. If you drag right to left, you will select everything crossing the window.

This tutorial will involve modelling the Villa Savoye by Le Corbusier.

The Villa Savoye (1929-1931), Poisy, Paris.

Display SettingsThe first step is to set up the correct display settings for our model. Sketchup has a number of different display and edge settings that can be used to change how your model is rendered.

To open the Display settings dialogue, left-click on Window > Styles > Edit. First, turn off Pro-files. Profiles excentuates the outlines of a model or surface, however it can be slightly difficult to work with when constructing a model.

Figure 8: The Display Settings dialogue box, showing the Edges option switched on.

Make sure that Extension is also switched off. Extension extends a line slightly past its end point to add a hand drawn feel to the image. This can be emphasized even more by switching on Jit-ter. Note, none of these effects how the line actually behaves during the construction phase. Try out how a cube would look like with different options turned on.

Setting layersThe layers palette is activated by selecting Window > Layers. Select Add (plus symbol) in the box and name layer 1 ground plan scan by typing over the highlighted text. Make the layer active by clicking in the small round button to the left of the newly named layer. A black spot should appear in the button to indicate that the layer is active. You can turn any layer (except the active layer) on or off by clicking the tick box to the right on the name.TIP: Ensure that colour by layer is NOT activated (to check click the small arrow in the top right of the palette). Downloading the drawingThe ground and top floor plans are available as jpg images, which must be imported into the program in order to trace them. The plans can be found in the folder called ‘Savoye’.

To insert the jpg plan select File>Import and locate the image called ground. When you have clicked Open, you will find that the image is now attached to the curser. Place the curser near the centre of the axis, and the lower left hand corner of the image should snap to centre point. Double click to fix its position - the size does not matter at this point. To set the correct scale, select the image, right-click, and then select Entity Info by left-clicking. Make sure the chain link

icon by the two dimensions is not broken, this indicates that the image will keep its aspect ratio when one dimension is altered. In the width box type 20850 mm and then click the chain link icon to set the height (it should be 22896) (figure 9).

Figure 9: The Entity Info dialogue box, showing the correct size for the image.

TIP: If using the Macintosh version of SketchUp, select file>insert and place the plan on top of the ground plane by single-clicking. Type 20850 to set the width of the plan and hit enter.

You may need to zoom in or out using one of the zoom tools (figure 10). Select the standard zoom tool, hold down the left mouse button and drag either up or down to zoom in or out. You can do the same using the scroll wheel on the mouse.

Figure 10: Clockwise from top left:

The rotate tool: click and drag to rotate your drawing (= holding down the scroll wheel).The pan tool; click and drag to move around your drawing (= shift + holding down the scroll wheel).The zoom extents tool; click to see the full extents of your drawing. Restore next viewing orientation: Redo your last view change.Restore last viewing orientation: Undo your last view change.The standard zoom tool; click and drag up or down to zoom in or out (= scroll in or out).

Before tracing over the image a new layer needs to be created in the same way as before and named ground floor plan. Make this layer current with both layers visible.

The ground floorThe next step is to draw a simple outline of the ground floor plan using both the pencil tool and the arc tool. Make sure that the perspective view is turned off, and switch to the top view (select Camera > Standard views > Top). Using the pencil tool draw around the straight lines of the plan towards the bottom of the image (figure 11b). You may find that zooming in while drawing helps.

Remember: SketchUp allows you to define the length of a line at any stage of drawing it by typing in its length (shown in the bottom right-hand corner of the screen). Alternatively you may use infer-ence points where lines are re-quired to be the same length.

If you hold SHIFT while the line you are drawing is aligned with an axis the line will stay in the di-rection of this axis and you can snap other points with interfer-ence lines easier.

Learning SketchUp: Villa Savoye Exercise Page 3

Select the pencil tool again in order to draw the left and right edges of the ground floor. Draw the left-hand line first. Left-click at the point that you wish to start the line and drag the mouse in the direction that you want the line to go in. The line will end where you press the ESC key on the keyboard or the shape is closed.

Now draw the right-hand line. Using the pencil tool start at the bottom by left-clicking and then move the cursor upwards. As the line is the same length it is possible to use the endpoints of the original left-hand line as a guide. When moving the cursor upwards a dotted inference line will al-low you to snap in line with the left-hand line so that both lines match (figure 12).

Figure 12: The green line on the right is being drawn from bottom to top. Notice that the red dashed inference line appears when the right-hand line is drawn to the same length as the left-hand line.

Using the arc tool draw in the curved edge of the plan. It may be easier to zoom into the plan at this stage, using any of the zoom tools or by scrolling the middle wheel of the mouse. Left-click where you want the arc to begin (an existing endpoint) and again at the point where it ends. The size of the arc can then be adjusted by moving the mouse in any direction and left-clicking. When you have drawn the arc the ground floor area should appear shaded to show that it is a solid 2D shape (figure 13).

Figure 13: Solid 2D shape of the ground floor.

Any unnecessary lines at this stage may be deleted using the erase tool or by selecting them and clicking delete on the keyboard.

In order to give the ground floor a three-dimensional form, the object must be extruded using the push/pull tool.

Switch to the ISO view, and then switch perspective back on. Select the push/pull tool and move the cursor over the face of the plan (the surface of the shape you have drawn will become tex-tured). Left-click keeping your finger on the mouse and move the cursor upwards. This will cause the plan to become extruded. Release the left mouse button and type in 3000 (mm) and press enter. Rotate the view using the orbit tool to see your work in 3D. Select the extruded object (click 3 times on the object), and select Edit > Make group.

Figure 14b: The extruded surface being converted into a group

This is a very important step. When you create geometry in SketchUp, it will always see if it can simplify it with any existing elements. This can lead to unexpected consequences of objects and elements becoming joined together, which is not always what you want. By grouping an object together when you have created it, you will prevent SketchUp from doing this.

The Villa’s columns are set out on a 5 m grid and are all the same size, so once one has been drawn it is possible to duplicate it. Draw the first column (bottom left) by selecting the circle tool. Position the purple point (centre) of the circle tool on top of the centre of the bottom-right column. Left-click to determine the centre point of the new circle and move the mouse to the circumference of the column. Left-click to complete the shape.

Click on the select icon and using this tool draw a box over the circle (left-click keeping your fin-ger on the mouse and drag a box shape from the top left to the bottom right which surrounds the shape). The circle should now turn blue to show that it has been selected. Extrude this to a height of 3000 using the push/pull tool. Select the whole extruded column and pick Edit > Make group to group all the elements that make up the column - this will make the next few stages easier.

Figure 15a and b: Using the move tool to copy and repeat (notice: 4x).

Holding down the Ctrl key (Strg key) on the keyboard whilst using the move tool can duplicate a shape (figure 15). Select the column and align the move tool to the lower circumference of the circle so that the pink endpoint is visible, press Ctrl (alt on a Mac) so that a small cross appears and left click. Keeping your finger on the left mouse button, move the circle to the column point directly above the first, and release the left mouse button (ensure that the green inference line is visible). The circle can be placed more accurately by now typing 5000 and pressing enter on the keyboard (note how the shape repositions itself). Rather than repeat this stage for each column in this row, type 4x and press enter and four copies of the original circle will be made. These can be deselected by using the select tool and left clicking outside of the image.

This feature can be used both vertically and horizontally on the ground plane, so repeat the stage in order to complete the external columns. It is important to use the inference guides so that the columns are perfectly aligned, for what may appear to be correct in plan may not be when viewed in perspective. Follow both the green and red dotted inference lines to ensure that your model is correct.

Turn off the ground floor scan layer by left clicking the visible icon in the layer manager to make it invisible and rotate the image using the orbit tool. Finally, select all the elements that are visible, and group them together. The completed ground floor should look something like figure 16.

Figure 16: The completed ground floor model.

The rampSet the view to plan by selecting Camera > Standard Views > Top. Ensure that perspective is OFF (Camera > Perspective). Create three new layers and name them top plan scan, ramp and top plan, making top plan scan the current/active layer. Place the top.jpg image onto the ground plane. Use the orbit tool to check that the image has been placed on the ground level and not onto the top of the ground floor.

Resize the image so that it measures 20850 mm by approximately 22900 mm (keep the existing aspect ratio). If required, move the imported top plan to align it with the imported ground plan scan using the Move tool. Make the ground floor plan layer invisible and select ramp as the cur-rent layer.

Using the rectangle and the line tool draw the shapes as shown in figure 17. This will become the ramp area.

Figure 17: The three rectangles that make up the ramp area.

The next stage is to use the Push Pull tool to extrude the shapes which create the ramp. Switch to the ISO view (the 3d representation of a house in the Views toolbar), and then select the Push Pull tool. Click on the top rectangle and extrude it to a height of 2000 mm. Repeat this for the left hand rectangle and you should be left with something that looks like figure 18.

Figure 18: The first two rectangles extruded.

Now select the Move tool, and click on the line highlighted in blue. We need to click and drag this upwards (following the blue axis!) to give the ramp its slope. Type in the correct amount, 2000 mm, and then press return (figure 19).

Figure 19: The top part of the ramp.

Select the push pull tool, and click on the right hand rectangle. Again, extrude this to a height of 2000mm, and select the edge highlighted in blue.

Use the camera Turn tool to look around inside a building model.

You can retrace over existing edges to re-create missing faces. Duplicate edges will not be cre-ated.

When a new edge starts or ends on an existing edge, the existing edge is split.

Figure 20: The lower edge of the ramp.

Click and drag the line down this time, so that it meets the bottom edge of the rectangle. The final step is to select all the parts of the ramp, and to group them together so that they do not interfere with any other geometry in the building (figure 21).

Figure 21: The completed ramp.

The first floorThe next are we need to work on is the accommodation block and the terrace wall on the first floor. After the ramp has been drawn on the ramp layer, select the layer top plan, and the make sure that you have switched to the top view. First, use the rectangle tool to draw a rectangle that cover the whole of plan (figure 22).

Figure 22: The outline of the accommodation block and terrace walls. Notice that the X-Ray button is turned on.

For this next stage, switch to the ISO view, and then select the Line tool. You will need to have the X-ray mode (View > Face Style > X-ray) switched on. Using the line tool, draw around the terrace area and the ramp, as shown in figure 23. You have to draw around the ramp once more because you are drawing in the top plan layer now.

Figure 23: The outline of the terrace and ramp areas.

Learning SketchUp: Villa Savoye Exercise Page 7

Click on the inside of the terrace area and the delete it (figure 24).

Figure 24: The deleted terrace area with X-Ray mode switched off.

We now need to extrude the accommodation block. Select the Push Pull tool, and then extrude it to the same height as the top of the ramp, 4000 mm. Because we grouped the ramp, SketchUp will not try and simplify the geometry.

Figure 25: The extruded accommodation area and terrace wall.

The final stage consists of two parts. We need to group all the elements of the first floor together, and then move the to the correct position relative to the ground floor. First, switch off the layer Top Floor Scan. This is to make sure it does not get grouped together with the ramp and accommoda-tion block. Select the ramp and accommodation block, and then select Edit > Make Group. Click on the Move tool, and then move the group up by 3000 mm following the blue axis (figure 26).

Figure 26: The completed first and second floors.

The roof terraceNow you will draw the roof terrace. Set the top plan scan layer to visible and create a new layer called roof plan, making this the current layer. Then set the ground plan scan, ground floor plan and top floor plan layers to invisible. Select Camera > Standard Views > Top to view the model in 2D from above.

You will now trace over the outline of the terrace area using the Line and Arc tools. You may find that zooming into the view helps.

Learning SketchUp: Villa Savoye Exercise Page 8

To infer a horizontal or vertical alignment from an existing point, briefly move the cursor over the point.

Figure 27: The initial shapes required in order to produce the roof model.

Firstly draw the outline to shape ‘A’ as shown in figure 27. Now draw shape ‘B’ which is slightly more complicated (the larger of the arcs be drawn in three separate parts that join together as indicated by the red lines). Any unwanted lines can be erased later.

Now make the top plan scan layer invisible, as this will make it easier to work.

You will now offset shape ‘B’ in order to create a thickness of the wall, an easier alternative to having to redraw the other side. Using the select tool, select all the lines that make up shape ‘B’. Then select the offset tool (figure 28) and first click on the selected lines and then move inside the shape, and type 200. Press enter to set the wall thickness.

Figure 28: The Offset tool

You will notice that two extra lines needs to be drawn that are not present in the original scanned plan (figure 29). This is to ensure that the shape becomes a face that can be extruded.

Figure 29a and b: The closed shape and the extra line that needs to be added.

The final step is to extrude both shapes by a distance of 2500, and then group them together.

Figure 30: The completed roof element in 3D. Viewing in 3DTo view the completed building in 3D you will first have to move the roof elements upwards by 7000 mm (blue axis). Finally, make the top floor plan, the ground floor plan and the ramp layers visible. All other layers should be invisible. Then using either the standard views under the view menu or the orbit tool the model can be viewed from a variety of angles (figure 31).

Page 9: SketchUp Tutorial V7 Villa Savoye

Institut für Städtebau . TU Graz SketchUp Tutorial

You can scale the entire model by entering a length after mea-suring between two points with the shift key down using the tape measure tool. Components cre-ated within the file scale with the rest of the model.

Double click with the Push/Pull tool to apply the last offset to a new face.

Learning SketchUp: Creating Sections Page 9

Figure 31: The completed building.

The section toolSketchUp allows you to use section planes to provide cut away views of your models. We will look at how these work by using the model of the Villa Savoye that was completed during the previous modelling exercise.

Firstly select the View > Toolbars. Make sure that section planes is selected and that the two icons in figure 32 are visible in the toolbar. If necessary this can be repositioned by left-clicking on the tool bar and (keeping your finger on the mouse) dragging it to a new position. This now serves as a shortcut to the section tools (figure 32).

Figure 32: The section tools. From left to right; display section planes; display section cuts icon.

In SketchUp the section plane will align to any surface to on your model. Select the add section plane icon (figure 33) by left-clicking the mouse and note how the green section plane boundary repositions itself as you move the mouse over the model. If you hold down the shift key on the keyboard whilst moving the mouse, the section plane will continue to align itself in one direction rather than that of any other face.

Figure 33: The place section plane icon.

Position the model and place the section plane as shown in figure 34. The section will be cut when you click the left mouse button, the green boundary will become orange and the section plane will be drawn.

Figure 34: Positioning a section plane within SketchUp.

If necessary this section plane can be repositioned by selecting the move tool. To do this first se-lect the plane with the select tool, next pick the move tool, left-click the mouse keeping your finger on the button and release the button in the new position that you wish to cut. This feature can be repeated as many times as necessary.

SketchUp allows you to use more than one section plane at a time. Simply select add section plane and position a new plane onto the model. When you have more than one section plane, you can double-left-click on the one you want to activate, or right-click on top of it and select active cut (figure 35).

Page 10: SketchUp Tutorial V7 Villa Savoye

Institut für Städtebau . TU Graz SketchUp Tutorial

By right clicking on a face, you can align the view or the sketch axes with the face.

Learning SketchUp: Creating Sections Page 10

Figure 35: Multiple section planes within a model. Double-click on a section plane to activate it.

The right mouse button has many uses within SketchUp. When right-clicking on a section plane selecting hide, for example, hides the grey section plane. By selecting reverse the section cut will be viewed from the opposite direction. Perhaps the most useful command is align view, which ro-tates a model so that it aligns with the section plane allowing you to look ‘inside’ a section (figure 36).

Figure 36: Using the align view command to look through a section into the building.

Grey section planes can then either be turned off by right-clicking on the plane and selecting hide or by selecting display section planes on the section shortcut toolbar. Sections can be shown in perspective or traditional orthogonal view, select Camera > Perspective to toggle between these two views.

Animating a sectionReturn the model to an Iso view Camera > Standard View > Iso, and ensure that perspective is activated (Camera > Perspective). Select the display section cuts icon within the section short-cut toolbar by left-clicking the mouse so that no sections are displayed. Select display section planes from the same toolbar so that the two sections that you drew earlier become visible as grey planes.

Using the select tool right-click on either section plane and right click to select activate cut (figure 37). You can move the section plane if desired by the move tool. Then click the Display Section Planes to remove the grey section plane.

Figure 37: Activate one cut

This view will now be saved as a page by selecting View > Animation > Add Page, the page will be saved as Scene 1 (if asked choose: Save as a new style). Repeat the process for the other sec-tion (select the display section planes. Right-click on the second section plane, press active cut and then deactivate the grey section planes ). Save this view as Scene 2.

Learning SketchUp: Creating Sections . Applying Materials Page 11

Having saved two different section views of the model, we can now animate these images. Sketch-Up will automatically show the progression from one image to the other, filling in the gaps in-between. Select View > Animation > Settings. Making sure that Enable Scene Transitions is se-lected, change the transition time to 6 seconds using the arrows with a Page Delay of 0 seconds. Press OK.

Select the View > Animation > Play and the image will move from the first section point to the second. Press stop when you have had enough. You can also animate the scenes by clicking the tabs Scene 1, Scene 2 etc. The SketchUp program fills in the gaps between the two and the animation can be made longer by including more pages into the slideshow, using the same tech-nique as above.

This is a simple introduction to the section applications. Hopefully, you can begin to see how the tool can give you a greater insight into how your modelled building actually works. By aligning the section plane horizontally rather than vertically, you will also be able to produce plans of your building.

The materials browserSketchUp comes with a number of materials that you can apply to surfaces within your models. SketchUp also allows materials to be made transparent. To access the materials select Window > Materials (figure 39).

Figure 39: The materials browser.

To apply a material to a surface single left-click on its thumbnail in the materials browser. When the cursor is moved over the model it will change to paint-bucket icon. Left-click with this icon on to the surface you which the material to be applied.

Figure 40: The materials browser with Villa Savoye that has had material textures applied to its surfaces.

Editing materialsIt is possible to edit the standard materials in order to create a custom material. To do this, select the material you want to edit and in the materials browser click on the tab Edit (figure 41). Once you apply it to a surface of your model this changed material will be saved under the In Model sec-tion of the materials library. You can also double click any texture in the libraries, edit it and then click add to save your changes in the In Model materials library.

To scale a material change the horizontal and vertical size. Drag the opacity slider to make a mate-rial transparent.

Figure 42: Two examples of changing a material via the edit material dialogue. On the left the material has been made slightly transparent, on the right the material has been scaled to make the bricks larger.

OutputWhen you have finished building a model in SketchUp you will usually want to either print it out or import it into another programme.

SketchUp allows models to be printed onto either a single sheet of paper or across multiple sheets of paper which can be tiled together to produce a larger image. Plans, sections, elevations and isometric views can also be printed to scale.

SketchUp prints models as you see them on screen. For example, if your model is shaded then the shadows will print. Also, if you can see the red, green and blue axes on screen then they will also print. For best results select view > axes to hide the axes and set your model to hidden line non-shaded (figure 43).

Figure 43: SketchUp model rendered hidden line with no shadows. The hidden line non-shaded render icon is shown.

You can change the colour of the background, the ground and the sky if you go to window > styles > edit >background (figure 44).

Figure 44: Background configurations

Print previewAs SketchUp has a wide range of printing options you should always select print preview (file > print preview) prior to printing to ensure that what you expect to get is what will actually print.

If you are printing a perspective view then it is not possible to set the print scale. Set your model to perspective (view > perspective) and pick print preview from the file menu. When the dialogue box opens select fit to page and use high accuracy HLR. Click OK to view how your model will print on an A4 page. To print click print, to cancel click close.

TIP: If you do not select fit to page then your model will be titled across a number of pages. If your print preview shows a blank white page this is probably because it the first of many tiles required to print a large version of your model. Click close and try again.

Page 13: SketchUp Tutorial V7 Villa Savoye

Institut für Städtebau . TU Graz SketchUp Tutorial

To centre your model on a single sheet of paper select ‘use model extents’ in the print preview dia-logue.

If the scale options are disabled then you are in perspective view.

Learning SketchUp: Output Page 13

Printing to scaleSketchUp allows plans, sections, elevations and isometric views to be printed to scale. To print to scale first ensure that you are not viewing your model in perspective mode (camera > perspec-tive). Next choose one of the pre-set views (iso, top, front etc.) and pick file > print preview.

To print your model to scale ensure that fit to page is not selected and type the appropriate scale in ’in the printout’ and ‘in sketchup’ (figure 43). For example, to print at 1:200 type 1 in ‘in the printout’ and 200 in ‘in sketchup’, to print at 1:50 type 1 in ‘in the printout’ and 50 in ‘in sketchup’. It does not matter if the scale units are set to inches, simply ensure that they are both set to the same units.

Figure 44: The print preview dialogue showing the scaling options.

Figure 45: SketchUp model shown on an A4 piece of paper at 1:200 scale.

FINAL TIP 1: When printing ensure that you can see all your model in the drawing window. If part of your model is not visible then this part will not print. FINAL TIP 2: To turn off the thick lines that may be visible around the edges of your model select window > styles > edit, pick the edge button and turn off profiles.

Exporting your model from SketchUpSketchUp models can be exported to other packages as either 3D models or 2D drawings and images:

• Export 3D model (file > export > 3D model)3d models can be exported in either AutoCAD or 3D studio file formats. If the AutoCAD format is selected then layer contents and names are retained. If the 3D studio format is selected then the layer structure is not exported. Components are exported in both formats, whereas materials, lights, and tab views are not exported in either format. As 3D studio can import AutoCAD files we recommend always using the AutoCAD file format. You can export all the formats with the Pro ver-sion of SketchUp but only Google Earth models with the free version.

• Export 2D drawing (file > export > 2D graphic)This allows 2D hidden line views (such as plans, sections, and perspectives) to be exported to other CAD or graphics programs (dwg, pdf). This option is only available with SketchUp Pro.

• Export image (file > export > 2D graphic)SketchUp views can be exported as bitmap image files in JPEG, PNG, TIFF or BMP formats. This

Page 14: SketchUp Tutorial V7 Villa Savoye

Institut für Städtebau . TU Graz SketchUp Tutorial

Learning SketchUp: Output Page 14

is extremely useful if you need to display a model on the web or in a desktop published report. Get the view you wish to export on screen and select file > export > 2D graphic. Select the required format (JPEG is usually best). By default the exported image will be the same size as the viewport window. To adjust this size click options (figure 46).

Figure 46: Image export options

Exporting AnimationOne of SketchUp many useful features, is the ability to export a series of views, or Pages as an animation for use in a presentation. When you export as an animation, each Page acts as what is known as a keyframe, with SketchUp moving the camera between them over a predetermined number of frames.

One thing that needs to be remembered is that SketchUp is not a traditional animation tool, in the sense that you cannot move an object between pages and expect to see its motion animated; only the camera itself moves. This can be worked around by having objects that you want to move contained on separate layers, and then switching layers on and off between pages.

How to animate a walk through using the Animation:

1: Prepare the view you want to be your opening scene. Use the Pan, Orbit and Camera position tools to set up the initial frame.

2: When you are happy, select View > Animation > Add scene.

3: Repeat this procedure until you have the desired path through your model. You can check how the animation will look by selecting View > Animation > Play. SketchUp will automatically show the progression from one image to the other, filling in the gaps in-between.

When you add a scene a tab appears above the main window, each time you add a scene, an-other tab will be added. The current page is highlighted, and you can quickly navigate from one scene to another by simply clicking on them.

You can also add scenes or move them to the left or right by right-clicking one of the scene tabs. Here you can also find the Scene manager, which can be set individually for each scene.

4: The next stage is to set up the length of your animation. Select View > Animation > Settings. Make sure that Enable Page Transitions is selected; otherwise you will simply get a collection of still images when you export the animation.

5: Next select an appropriate transition time. This is the length of time between each Page of the animation. The total running time in seconds will be the number of Pages multiplied by this num-ber.

6: Select the length of time for the page delay. This is the length of time the animation will pause on each page before moving on to the next page.

7: Before you export the finished animation, again check the animation by playing the sideshow. If you need to make any alterations, stop the animation on the particular page, and make any changes using the pan, camera and orbit tools. To update the page, right click on the tab and select Update.

For web use anything up to 320 x 240 is sufficient. For stand alone viewing on a computer then 640 x 480 is more appropriate.

8: Click File > Export > Animation, then click the Options box in the bottom right hand corner of the dialogue box.

9: Under Settings, enter the screen size you want the finished movie to be. Bare in mind that the larger the movie the longer it will take to save. Larger movies will also take longer to download over the web if you are planning to embed it in a web page.

10: You now need to set the frame rate. Again you will need to choose one appropriate to how the movie is going to be viewed. 12 frames per second is appropriate for a web based movie, 15 to 24 for a stand alone movie.

11: The final two things to check are Loop to starting page and Anti-alias. The Loop to Starting Page option generates an additional set of frames from the last page of your animation to the first, forming a continuous loop of video. The Anti-Alias option smoothes the exported image, by blur-ring edges slightly to give the impression of a smooth line. This option can increase the export time, however generally results in a more polished final appearance.

12: When you are happy, Click Ok. Name your file, make sure that the file type is set to Avi File (*.avi) and then click Export. SketchUp will now render your movie. How long this takes will de-pend on the size of frame and or the framerate.
