Hello, I have another problem in drawing shapes My goal is to have a small box inside a big box, The small box has 1 plane common with the big box See attached .geofile When meshing this, the small box is 3D meshed, but the big box is only 2D Why is the big box only 2D meshed, and why not 3D? How do I need to draw it so both boxes are 3D meshed? Thanks, Nout
