I created two meshes surfaces from point clouds with MeshPatch command . One top surface represent a terrain topography the other one the bottom of the terrain. I 'm looking for a command to join these two surfaces in order to create a closed volume suitable for 3D printing .On a small test I used the command " add a mesh face" by manually selecting faces, one by one, on the edge of the top mesh and then selecting the corresponding faces on the edge of the bottom mesh. Obviously it’s impossible to do it this way with a bigger mesh with thousand faces! Is there a way to join these two meshes an other way??
Thank you very much for any help!
