i found a version of aspire that was of... dubious origin. I'm able to save the file as their format... but not reopen them. i'm able to export as DXF or whatever, and able to load them... i just have to manually re-enter the sheet dimensions everytime...not totally functional, but functional enough that i could get it to our CNC guy. the parts turned out great, accurately dimensionalized, and easy enough to tweak to add holes and whatnot.
Aspire is a very nice program to use and I will entertain purchasing the software if I end up getting a CNC unit of my own. i'm currently looking at a kit that once I get moved in the next couple months...I may buy it, build it, and set up at home in my garage... then perhaps I'll convince the boss to pay me to cut out the cocktail kits instead.
