thx for your nice words ... work with viacad 2d/3d is more constructive then moi, but has some nice parts to play with ... moi is more intuitive and you can work very fast to create something ... i like both. 
to get .obj out of viacad 2d/3d (doesen't support .obj) i export .iges, load it in moi and get wonderfull .obj out for my xsi.  
for the newest cinema 4d you can use .dwg comming out of viacad 2d/3d.
 
and now, some texturing ;)
  
build in moi:
