Maybe I'm a little ot x which is not exactly a comparison.. .
you know how to tell me what they use to do these planes:http://www.jintudesigns.com/3d-floor-plan.htmlIs it their own software, owner?
Thank you.

any software to make rendering...3ds, 4d cinema, blender...who can say?

they cut by hand and made the render with any engine. otherwise if you do not want to cut the models by hand, you should find a sw to render that supports the section plans, you can with maxwell and fryrender.

you can download from the free 3d objects site.
those few I have seen have extension .3ds
I suspect they use 3ds even if it is not said.
