Hi Guys I'm new to the forum so first of all, hello!

I'll try to keep the post as concise as possible...

I have a large historic landscape project underway. The first part has gone to plan. The contour data was generated in a/cad exported (linked) into Viz, spline normalised -> terrain, no problem.

So I have my base landscape. However part of the brief is to display the land (field boundaries etc..) as was recorded in the mid 18thC. We have accurate geo-referenced fields which have also been created in a/cad and overlayed onto the contours.

But I can find no way to "drape" (for want of a better description) the new splines over the existing terrain. They obviously come in on a flat plane. I have tried various options such Itoo's glue plugin but this dosn't work. What I'm trying to do is overlay the new fields as a layer, or individually, but can find no way to accurately have the splines/mesh/patch follow the surface terrain created from the contours..

Can anyone suggest a way to do this or a plugin that may help?

Many thanks in advance
