Wow, wonderful work! 
 
That ViaCAD looks handy - price isn't too bad either - what export format do you use to get stuff out? 
 
I thought I saw "Rhino" export on the ViaCAD info page but the demo doesn't show ".3DM" or anything I'd like to use to go into Cinema 4D or XSI (like OBJ) ??

PS - I see Rhino import but all the export formats seem to be triangulated (no OBJ for example)
