Terramodel DTM hole – how to ?

How to create a hole in the surface in Terramodel.

I is not as easy as in Business Center – HCE where you just need two boundaries and that is it.

In TerraModel you need to create one solid boundary which somwhere along the way breaks and jumps into the desired hole (where you trace your hole) and  jumps back out but not overlaps. I personally use a 3mm gap, this does not affect my volume by much and I get the desired result. Once that is done you will need to erase the points in the hole so no triangle are created.

This is how to create a DTM hole in Terramodel.
