how can I join the meshes to make it a one big shape? Meshes are 0cm thick, so they are basically 2D.
You will need to do it one by one:
Select one Mesh, click on its edge to bring up the Pet Palette, select the Add to Polygon option (third from top right), hold down the Spacebar to bring up the Magic Wand, click on the edge of another Mesh. The second Mesh will still be there, so may need to be deleted.
If the Meshes were Fills, you could use the
Fill Consolidation command.
You should add a Signature to your Profile (click the Profile button near the top of this page) with your ArchiCAD version and operating system (see mine for an example) for more accurate help in this forum.
