![]() ![]() ![]() One important thing to keep in the back of your mind is making sure your designs are manifold. Being able to assign dimensions to a variable and then generate the object from those allows you to make parametric designs. OpenSCAD has one especially powerful feature: variables. If you like to design mathematical forms, or really like writing code, OpenSCAD is for you (it has for loops). It uses a code-like design process, much like POV-RAY or other ray tracing programs. This means that you make your object by combining primitive forms. OpenSCAD is a CSG (constructive solid geometry) modeler. A tool like blender is a good option if you like to sculpt or 'feel' out designs as you work. You can then shape these meshes into your designs. Blender is also a mesh modeler, meaning your designs are made of triangle meshes. Blender is a very powerful modeling and animation tool. One popular option for 3D work is Blender. For this article, I'll only use open-source cross-platform tools. Your choice of software affects your design process, and to an extent the way you think about design. ![]()
