Easy to use for quickly roughing out a building
The software is easy to use. It allows me to quickly bang out a rough design for a building. I give it 4 stars instead of 5 because I wish it had a more extensive set of doors, windows and store fronts. More building details would also be welcomed. I typically use Model Builder to create the basic building, export that as a pdf and then add further details in a photo editing program.

Fills the Voids for Me
I like the siplicity of the software - it is limited and unsophisticated, but it does exactly what I need it to do in my projects and that is to fill the void of what I have and what i need/want. This really helps for simple mockups and makes parts for me at will. I cannot ask for more. I would love more add-ins and would pay for the right ones. Thanks!!
