Styles

Styles control the visual appearance of your model

You can create a number of styles with predefined settings for model faces, line types, backgrounds etc

Keep careful track of your styles:Note when styles are being updated,

don’t go creating multiple versions of the same style

Keep your style naming clear, it helps when working in layout

Styles and Style Builder

Cycle through editing options

Hit the update button to keep styles current


Styles

Suggested styles for your templateWorking style (section panes, guides etc on, some layers off for faster modelling)X-Ray Style (Working style with X-Ray on)Hidden line (simple hidden line, no textures, for faster modelling)Sketch Style (sketch style for quick presentations)Presentation style (with textures, transparency, all layers etc on)



Style Builder

Style builder lets you build your own sketchy style from your own drawing styleStyle builder is separate software which only comes with SketchUP ProTo create your own style

Hand draw your sketchy lines like this:Scan them in and save individual jpg files of each lineImport the lines into Style BuilderAdjust the scale and colour of your line-typeSave the style into a library and you can use it in your model

Websites to source SketchUp Plugins

A list of websites to source useful pluginshttp://smustard.com/http://sketchup.google.com/download/plugins.html (heaps of links to other

plugins)http://rhin.crai.archi.fr/RubyLibraryDepot/Ruby/RUBY_Library_Depot.htmhttp://www.1001bit.com/

A couple of the more useful pluginsMakefaces: Generates faces from closed .dwg geometry. Useful for creating

geometry from imported .dwg filesLayerchange: Allows you to control the active layer by right-clicking on a

selectionSimplify contours: Simplifies contour geometry making surfaces created less

complex and easier to work with.

Using Layers

Use layers to break up your model into digestible parts

Suggested basic list of layers:Surfaces created using the sandbox

toolsVegetationFurniturePeople

Use scenes to isolate layer geometry



Using Outliner

Use of the outliner assumes most model elements are groups or componentsOutliner displays a hierarchy of groups and components and allows you to isolate geometryThe use of the outliner has advantages over layers as it doesn’t depend on elements being modeled in the correct layer Keeping elements grouped or in components also controls how geometry interacts


The outliner tree of components


Component Replacement

Low resolution place-markers are good as temporary substitutes to complex components

Create a simple component to represent an diagrammatic tree

You will need a separate component for each type of tree you will want to replace,

Place these components in the locations you want the complex components to reside.

When the time comes 'right-click' on the component to wish to replace and select the ‘reload’ option. Browse to the more complex component.


Create a simple component

Copy components and place them in position

Complex components substituted


Modifying Textures

There is some control of the appearance of textures from within the Window > Materials tab.

To edit any of the standard materials you need to select the 'create material' button

From here you can adjust the size / scale and colour of the texture map

Textures and Materials

Create new material and edit properties


Modifying Textures

Once a material is painted on a surface you can edit the scale and position of the texture by right-clicking on the surface and using 'texture > Position‘

From here you can play with its position, scale and orientation on the surface.

Right-clicking on the pins gives you the option to 'unfix' the pins so the texture can be scaled.

These changes apply to this surface only and don't affect the source material


'Right-click' on texture to edit Manipulate pins to edit texture


Using Images as Textures

Crop your image as much as possibleIn SketchUp, select File > Import, select

your image, choose 'Use as texture'Click on the face you wish to apply the

texture to. Then stretch the texture across the face and click again.

Edit your texture by right clicking on the face and choose Texture > Position

Click on a pin once to pick it up then move it to a desired corner on the texture. Repeat for the remaining pins and corners.

Right click on the image and uncheck the “Fixed Pins” option. Then click and drag the pins to the corners of the model.


Stretch texture on surface

Edit texture, move pins to corners of image

Cut surface to match building profile


Using Photomatch

Find a picture of your building that shows a two point perspective (a corner shot).

Select File > Import, select your image, choose “as new matched photo”

Move the origin of your model so the base of your building model matches the base of the photo.

Align the Green and Red bars with horizontal lines on the building in the image. Don't use the ground line as often this is not flat.


Select the 'use as matched photo' option

Align axis with building and drag to adjust perspective and grid


Using Photomatch

Open Window > Match Photo. From here you can adjust the spacing of the grid to a scale suited to the building.

Move the mouse over the blue axis and click and drag to zoom the image to the correct scale.

Click Done in the match photo window.

Model the remainder of the building to match the photo.

Once your building is modelled you can right-click on any surface on your model and select 'Project Photo'


Model built to match photo

'Right-click' and select 'project photo'


Using Streetview

'right-click' on any surface and select the 'Get Photo Texture' option.

A separate window will open with street view open. Locate your building and select the 'Select Region' button.

Drag the pins in each corner of the highlighted section to the corners of your building.

Click the Grab button to grab the selected portion of the Street View image and apply it as a texture to your building in SketchUp.


Orientate street view window

Drag pins to select region

Select 'grab' and image selection applies to model surface


Creating a surface

Import the .dwg and if necessary isolate the contour geometry.

Ensure the contours are groupedEdit the group and highlight all contours

you wish to use to create your surface. With the contours still highlighted select the 'create from contours' icon from the sandbox menu and your surface is created.

If the contours are to detailed you can download the 'simplify contours' ruby script

Once the surface is created you can delete the contour group and modify the surface as required using the sandbox tools.

Sandbox and Topography

Select contours

Select 'from contour' from the sandbox menu


Using Drape and Stamp

The stamp tool allows you to stamp a profile into the surface and create either a plateau or recess for that shape.

The drape tool vertically projects a shape onto the surface from above


Drape tool Stamp tool


Creating contours

Create a flat plane larger than your modified surface, group it.

Ensure the plane sits just above the lowest point of your surface

Copy the plane vertically to the interval of your contours

Array this copy until the highest flat plane exceeds the height of the tallest point of your surface

Right click on the grouped planes and select 'intersect with model'.

Delete any remaining surfaces and what is left is a set of contours


Create plane larger than surface

Array plane in desired contour increments

Delete surface leaving contours


Creating a Dynamic Component

Dynamic Components are SketchUp components to which attributes can be assigned.

To make a component dynamic you need to add attributes, you do this by right clicking on any component and selecting Dynamic Components and Component attributes.

Each attribute added assigns a parameter to the component, some parameters can contain information, others can allow interaction with the component and others constrain certain geometry.

Parametric SketchUp Components

Component flexes on scaling


Dimensioning visibility

Open Window > Model Info > Dimensions > Expert Dimension Settings

From here you can force dimensions not on planes perpendicular to the cameras to turn off

The angle of vision can be controlled by the slide barTo align a view with a particular face right-click on the face and select Align

View

Dimensioning

Model without dimensions foreshortened Model with dimensions foreshortened


Text and Dimensions

To add text but keep the dimension string current replace the dimension value with '<>' and the dimension value will appear and remain dynamic. Adding the text \n will place a return in the dimension string

Dimensioning

Dynamic dimension


Clipping masks

You can create a custom clipping mask to crop any view in Layout,

Clipping masks are created by a joined loop of lines

Trace your linesTurn off fillSelect both the loop and viewRight-click and select 'create

clipping mask'

Layout

Create enclosed loop

View with clipping mask


Dimensioning

Dimensions automatically snap to points in the SketchUp models you insert. Turn on snapping with Arrange > Object SnapDimensions, lines, labels and other elements that you create while snapped

to points in a model are sticky; they remain attached when the underlying model view is moved around on your page

Layout


Templates

Place title block elements which aren't to be edited on their own layer

Keep any text you want to edit on the title bock on their own layer

In the layer window select the 'display on all sheets' option for elements which aren't to be edited and Lock this layer

Save the file as your template in a separate folder

Load this folder into your template file list under Edit > Preferences

Layout

Layer to appear on every page

Add folder to template list


Editing Vector Graphics

In the SketchUP Model window change the rendering type from Raster to Vector or Hybrid

Right-click on your model view and select Explode

Right-click on your model again and select Ungroup

From here you can select the various groups of linework in your model, ungroup them and modify them to your hearts content.

Layout

Select hybrid graphics Adjusted line styles


The suitability of integrated geometry

Two useful resources are in the REVIT help files:suitability of imported geometryImport SketchUp files

Different file formats maybe imported with different qualities of geometry, this means that export settings and the quality of your model is just as important as how it is imported import settings.

The use of layers in SketchUp is useful to control your model in REVIT

Integrating SketchUP Into REVIT


SketchUP Files as Mass Elements

SketchUP files can be read as mass elements in REVITAs mass elements the SketchUp file can then be used as a base to begin your REVIT modelWall and Floor by face wont work well on complex surfaces so this assumes a simple and well built SketchUP model



ICF files in SketchUP

IFC2SKP is an IFC converter for SketchUPIt lets you import IFC models into

SketchUP which retain their IFC data.

Download from http://www.ohyeahcad.com/ifc2skp/index.php

Use the Load Model command to select the file you wish to use and use the Show Model command to import the geometry you want from the IFC

This is much better than importing dwg files into SketchUP as the geometry is much easier to handle
