[net.graphics] Looking for mechanical CAD modeling & drafting on VAX/UNIX

patch@ogcvax.UUCP (08/30/84)

-----------

I am looking for mechanical modeling system, and a drafting system
that runs on DEC VAX under UNIX.  The system should have:

MODELING:
	CGS (constructive geometry system) for 3D solids modeling
	X-sectioning ability.
	Boundary modeling capability.
	IGES graphics output for input to the drafting system
	Shaded color picture capability
	Multiple object assembly to look for interferences

DRAFTING:
	IGES graphics input from the modeling system
	auto dimensioning
	auto filleting with trim
	traslate, duplicate, rotate and drag of objects
	multiple layers (color)
	parametric equation input of geometry

These systems should be fully-supported, I am NOT interested in
anything that is not comercially available. 
If you are a vendor of such a system, or know of where I can get
information please respond via E-mail or preferably to:
