I checked it out! This is amazing! It's a watered down version of SpaceClaim! Three things that I noticed right off are:
It uses DirectX 9 so it runs great on PCs with crappy graphics cards.
It converts native Sketchup files directly to solids!
It really is easy to use! The only thing I had to look up so far is how to pan, middle mouse button + shift.
I really like the functionality! I didn't know SpaceClaim was such a nice software. In their full version they've put a lot of effort into helping people convert polygonal files to solids and that right there is major kudos to me. As seen
here. Some of this same functionality is in this DesignSpark version but I haven't had enough time to look into this fully.
Being that SpaceClaim is only around $2500 US, it's worth learning just in case I ever want upgrade to the full version, so I'll most definitely use this on my next engineering type project and learn its intricate workings!
