Solidworks
The ultimate. Full parametric solid modeling and parametric 2D sketching. This programe is used to honestly design parts for production and solve challenging geometry problems. I couldn't live without it.
BikeCAD
BikeCAD is a very inexpensive and very well designed peice of software for framebuilders. Brent is constantly improving it and providing updates. I often use it and suggest it to folks.
RattleCAD
RattleCAD is a free software package similar to BikeCAD. I don't know anyone that has used it.
