Hi There, Im currently trying to replicate a 2d drawing of a basic exhaust system in AMEP 2014. I have most of it worked out, But we have used a 2d background from the original project and just drawn duct & grilles etc in 3d. But I cannot get the duct to wipe out the background under neath. Im sure its in display manager somewhere. Could anyone please give me a point in the right direction? Thanks
