Delcam is making a free evaluation copy of its PowerShape hybrid CAD
modeller available to all who visit its web site. You need to go to:
www.delcam.com/download-pshape/download.htm
The evaluation copy has all the functionality of the current release for
both solid and surface modelling but has the save capability disabled. A
series of tutorials has been added, and it is recommended that these are
completed before trying the software on any original design work.
The software comes with Delcam's IGES translator, so data can be imported
from other CAD systems and modified within PowerShape.
