For the price I decided it would be worth trying out the Pro version.
So far (I haven't gotten too complicated) it is well worth the cost! As easy as RoofBuilder Tools is (if you don't have it ... GET IT!) in Dcad, this Plug-In for SU is even easier. It will take a little trial/error along with the tutorials to get into how the plug-in thinks, but once I get the hang of it it will pay for itself with the first roof it generates.
Between DC, SU and this SU Plug-in there is NO reason NOT to model in 3D to create your elevations automatically (export them FROM SU into DC).
Just my opinion ....
