Connecting meshes

Rhino

I have these 2 meshes - the inner one is a patch of terrain, while the rest is just a cylinder - and I want to create another mesh connecting them.

The only way I can think of doing this is using a loft but that’s just for surfaces (these meshes are too big for MeshToNurb command, and also I would rather keep them as meshes if possible).

These are the meshes I’m talking about:

And that blue region is what I want to achieve (but as a mesh, that one is just a polysurface). That blue mesh needs to connect to the other other perfectly since I need a closed mesh.

Hi @robneto.eng, extract the naked borders of both meshes to get 2 polylines. If both polylines are planar and in the same plane, you can use _PlanarMesh to build a new mesh from them. If they are not perfectly planar, use _MeshPatch and pick both polylines when it asks for points and curves, when it asks for holes, pick only the inner polyline.

Before joining all meshes, check that the new mesh matches the desired normal direction using _Dir and _Flip if requried.
