Creating a straight box base contour around a 3d curved su
- 
 When creating a topo surface from cad file lines the surface is a thin chip like object. 
 I want to give it a real cardboard model feel by closing the area under the surface into a closed box.whats the best way to do this? the surface has many edges and I cant make anything intersect with it in a single swipe. attached is an image of the surface and a box under it. I want the box walls to fit the surface edge so it doesn't seem floating like it does. is there a quick and simple way to do this that I am missing? Thanks!

I had to delete the surface and only use the outline since the plugin made a projection of every small face in it but pretty good.

 If you select only the outer edges and choose the last icon of the toolbar it project edges along a vector.
