The handles that I found very useful for modifying 2D objects are also available in 3D, as demonstrated in Figure 6. This makes TurboCAD an excellent tool for 3D conceptual studies. I did find it a bit tricky to stretch a 3D shape in only one direction, as the handles for doing this are invisible. Rendering The rendering in the program has been improved by the incorporation of the LightWorks rendering engine. Materials can be placed on objects, and dozens are available, including various woods, plastics and metals.
Users can also employ their own bitmap files.
Any material's pattern, reflectance, transparency, texture and wrap can all be defined. Next the lighting can be added, and this turns out to be an area where the program can be improved. It wasn't obvious how to position lights in order to get them to shine exactly where desired. After struggling for a while, I right-clicked and found out that I had to employ the Edit Node command to move the light's position and orientation. Also, adding a light is not just a simple case of click and drag as is the case with many other programs.
