To avoid the problem of hatching wall insulation lines in 2d I was trying to make a VA Grasshopper wall with those insulation lines (swiss insulation hatch) included, see below. That however does not seem to work as VA Wall 2d line representation nor does it work as 2d extruded surfaces. Only the wall volume brep is visible after importing it as Grasshopper VA Wall Style. Maybe lines and surfaces are not supported by the grasshopper wall or i am making a mistake? Maybe someone can tell me what i am missing?
