Looking for 3-D CAD software for Sun

[Junan Chen]

Hi there.  We are working on the 3-D solid object modelling on the Sun
Sparc-2 workstation and we need the kind of software like AUTOCAD for PC,
which allows us

1. drawing any 3-D solid objects and/or polyhedrons
2. projecting 3-D object in any given viewing direction

Lighting and shading are not required.  Either Public domain or commercial
is fine with us.  If you have any idea about the available 3-D CAD
software of the sort, please email to this account or
chen at eleceng.ee.queensu.ca

Thank you for your help.
