I have an arch I created in 2D CAD, converted to a solid, converted to a symbol, and set the "Inserts Into Wall"   but when I put it on the wall, it cuts a rectangle instead of the arch.  Any idea why? symbol:     plan view:   then I move the symbol to the left over the wall and widen it and I get a rectangular cutout:   then I deselct the layer for the symbol     Any ideas why I do not get the arch?
