Mesh

Hi there,

I would like to create a mesh with an earth hatch for this drawing (required mesh shape shown in red).

Is there a way to manipulate the mesh in section to make this possible?

Operating system used: Windows 11

yes it is possible. A mesh is a 3d model. You are working in a section. The quick solution would be to place a fill with the earth hatch over this drawing....

you will want to place a site mesh that includes contours and elevation changes. It should be at least as thick as the building (low to high point), then using solid element operations (design > solid element operations) select your slabs/stairs/walls that are 'below grade' or overlapping the mesh, set those as the operators, set the mesh as a target, subtract with upward extrusion.
