@Frenchy: Yeah, it does G2 for Blends and stuff, but not for filleting.

I get some graphics glitches on Windows 8 Pro x64 with a GeForce GTX 660 TI and latest drivers. Refresh issues with 2D stuff mostly.
The version 6 demo was pretty much unusable on my system because those glitches covered the whole screen. V8 is way better, but still not perfect and the screen refresh can get slow with 4 views.
I hope I can find a solution - somehow I wasn't able to log into their forum yet.

But for the price it's pretty amazing as an addition to MoI and has some cool tricks, although I like MoIs workflow a lot more in most areas - some thinking in ViaCAD is a bit more convoluted.

Cheers,
