I have recently downloaded a trial version of SpaceClaim Engineer just to see what it was about. It is an interesting diversion from the typical 3D packages. SpaceClaim uses 'pull handles' in a unique fashion to edit most all features on the fly. The aspect I like the most is that the software can import a variety of formats while retaining the ability to edit individual features cleanly. With most of the packages I have used in the past, imported STEP files end up as dumb solids that are awkward and time-comsuming to change. It's nice to see somebody does it right for a change. This system doesn't have the horsepower to compete with SolidWorks, ProE, Inventor, etc...but it may develop a niche market somewhere. My questions: 1) Does anyone else out there use the package? 2) If you do, what are your thoughts about its advantages/disadvantages/ Thanks.
