The operation was smooth and quite intuitive. It will be necessary to remember the keyboard commands though, as there is no alternative way to initiate these operations provided anywhere on the program's pulldown menus. As for 3D modeling, an impressive range of surface editing functions are provided, enhanced by the ability to modify geometry interactively once it has been created. For industrial design applications, where aesthetic appearance is important, this is a marvelous capability. As far as the particular functions available in solidThinking 3.0, for drawing lines in space a good range of options are provided.
Standard commands exist for creating arcs, circles, ellipses, lines and polylines.
Curves can also be produced by applying an offset or blending, extracting a curve from the edge of a surface or projecting a curve onto a surface. For 3D surface construction, a range of primitives is provided, these being spheres, cylinders, cubes, prisms or the torus. Also on hand is an easily implemented 3D text tool, to create 3D text using your choice of TrueType font. There is an interesting Height Field option. This worked very well and gave some interesting results.
