I would like a MeshGrid component. It should be easy because the rendernet component already exists.
If you think that it is useless, well, trust me, it is not
By grid you mean a 2d net/grid, just like rendernet? I think I can fix this easily by adding a checkbox to the MeshBox-component that it should only create a 2d rectangle instead of a box. And I can see why you need this now that I've seen the work you do with meshexpressions
