How to Model a Rietveld Chair in SOLIDWORKS?

Today I will show you how to model the famous Rietveld Chair in SOLIDWORKS. Gerrit Thomas Rietveld was one of the most outstanding furniture designers in the Netherlands. One of his most famous designs is the Red and Blue Chair. I thought it would be nice to write a SOLIDWORKS tutorial about this chair.

In this tutorial you will discover how to use the following features:

• 2D sketch
• Extruded Boss/Base
• Thin Extrude
• Multi-directed Extrude
• Mirror
• Chamfer

When the model is finished I will show you four different ways to add color to your chair.

Happy modeling!
