I've used this product to create three dimensional models of buildings, bridges, roads etc that are not only visually stunning but also extremely useful in many engineering applications. In addition it is very easy to use with all users able to understand how they work without any training required! As far as my experience goes there was nothing really bad about using this software so if you're looking at alternatives make sure you look around because maybe none exist yet? However having looked through their website now I see some improvements could be made such as more tutorials being offered or even better integration into other CAD softwares (eCAD).

We have created several large scale model projects including detailed drawings of.
