Hi BlackBird, I'm glad that you are liking MoI!

Yes, you will usually want to use different tools for different kinds of models. MoI is particularly good for models that are defined by 2D profile curves and have things like cuts and holes in them. A lot of mechanical man-made parts often fall in this category.

Blender or other poly modelers are good for models that are more organic and sculpted looking shapes, things like monsters, faces, etc...

I do not have anything set up on facebook, this forum here is the main place to find MoI information.
