Chair Modeling TutorialSpline technique

This is a basic tutorial of the Florence Design Academy www.FlorenceDesignAcademy.com to understandhow to use the SPLINES effectively in the field of Interior/Furniture Design. This tutorial is based only onsplines. It is very important that your chair has the correct dimensions, otherwise the rendering withMental Ray will not be optimal. Let's begin our tutorial.

Create a rectangle in the TOP view. Make a right mouse button click (RMC) on it and choose convert toeditable spline.

Select the segments like in the image above and go to the slot DIVIDE. Put the number 2 in the slot andclick on the button DIVIDE. This will create 2 additional vertexes on each selected segment.

Select all vertexes and make a right mouse button click on them. Now choose CORNER (there are 4different types of vertexes: Corner, Smooth, Bezier and Bezier Corner). This step will make the next stepseasier.

Now select the vertexes like in step 1 and move them down and left to get the shape of step 2. After thisstep select the vertexes of step 2 and move them right to get the shape of step 3. The end result seems to

be a flipped letter C. Important: remember that in the front view you see only one side of the chair. Makealways a REGION selection to be sure that you are selecting the vertexes on both sides of the chair.

This is now what you can see in the perspective view.

To create a 3D Object you must go to the modify panel and enable 2 slots which are : Enable in Rendererand Enable in Viewport. This will transform your spline in a object in which you can choose to change afew parameters. For our chair we need a radial section. Choose Radial and write in the thickness slot thediameter size .

Select all vertexes and go to the command FILLET. This will round your sharp corners.

Create a new spline with the shape of the letterL.

Check again the slots enable in rendererand enable in viewport. Now select the vertex like in the pictureand fillet it.

Change the left view to a right view. In this way we can see the circular shape of our spline. Now create acircle (spline) in the center of the circular section of the spline like in the image. You need to convert it into

an editable spline to be able to work with the vertexes of the circle.

Select the vertex like in the image, and BREAK it. This will split a single vertex in 2 vetexes and break thecircle.

Select the upper vertex and move it to the right side. Transform the vertex with a right mouse button clickinto a CORNER vertex.

Move the lower vertex like in the image and use the Bezier (also Bezier-corner works very good in thissituation).

Now select SPLINE and MIRROR it with COPY. Move the copy to the opposite side of the chair. Move itonly from the X axis. You can mirror the spline from the modify panel or just using the Mirror tool. If you usethe Mirror tool you have to ATTACH the two splines to be able to weld the vertexes.

Select this 2 vertexes. Now go to the Weld button. Insert a big number in the weld slot and click weld. Thenumber that you must write in the slot must be equal or bigger than the distance between the vertexes thatyou must weld. The easiest way is just to write a very big number like 100000.

Now select SPLINE and outline the spline.

Add an EXTRUDE modifierfrom the modifier listto the spline and adjust the amount of the modifier.

Now you should have this result.

Copy and rotate the extruded object like in the picture.

From the Right view create a spline like on the image above.

Now outline it (SPLINE).


4/4

Extrude the spline and mirror it to the other side of the chair.

Now you should have this result.

Create a sphere and squeeze (scale) it in only one axis to make it flat.

Create in each marked point a flat sphere.

Create in each marked point a cylinder.

Create an arc (Spline), enable it inrenderer and viewport like in the image.

Copy the arc like in the picture

Here you can see the final result.

I hope you have enjoyed this tutorial.
