Hi Michael ...

Yes, that method works perfectly.

I generally use contour lines and "sweep" to build terrain and to make changes as needed for my projects even though I have other software that will do it automatically with point clouds or a group of contour lines. I simply like working with MoI for as much of my work as possible.

I have been working on this particular project for years and built the original model with a combination of other software. I have a feeling that some holes occurred over time modifying grading plans with meshes that MoI does not read. It is a Tibetan Buddhist retreat and Temple built in stages as donations come in. Over time modifications and budget changes are a fact of life.

All is well now, and thanks.
