Re: [CAD_CAM_EDM_DRO] Comparison of Cadd

I'll have to disagree with you Marcus. In my experienced opinion, learning
to draw in 2D first is the only way to go...sort of like learning to walk
before learning to hop, skip, run or jump. Learning in 2D provides the
necessary foundation for any future enineering trade. Furthermore, a
skilled designer should be able to visualize any component in 3D just by
looking at a 2D drawing. The abbreviated CAD packages based on AutoCAD are
NOT counterintuitive and unfriendly. Lack of familiarity with the program
creates the impression of being counterintuitive and unfriendly.

On top of all that...any beginning draftsperson will be REQUIRED (in any
school I've ever heard of) to learn 2D drafting first.

Also, as Chris pointed out....it is ideal for converting drawings to tool
paths for CNC programing...a simple click of the mouse on any line in the
drawing provides all co-ordinates and radii (if any) required.

I AM a serious designer. I use Rhino for my 3D program and the only thing I
need it for is to convert my 2D drawings when I need to print a "photo" for
those lacking the ability to visualize in 3D from a 2D drawing.
