MegaMan,
I use HexaGreat cuz as far as I know HexaSuper is only for Mac. One guy did offer to give me a PC version he had translated but I never got around to it. Hopefully shusaku (maker) will find a US market cuz I think it would totally enable beginners to do 3d (like me).
HG crashes like mad but you can save stuff in dxf format, which if you have another program like TrueSpace or something then you can export as X. HX is the easiest 3d program I've ever used, but as stated, very unstable.
You can do a sort of angled 2d/3d tracing with a background bitmap for reference. It's like an isometric angle, and once you draw at that angle then you rotate and convert it to 3d. I still use it for getting accurate shapes from bitmaps (you could even use drawings.) The trick is to save your stuff and export it as DXFs as often as possible because if it crashes while you are working on something (for me) it will never let you open that HG file again (not even copies of it with different names).
But the DXFs will be safe cuz they aren't in the HG format. That's one serious bug!
