By lofting both together I was thinking you were lofting the inside of the arch. This would work great if the archway was a defined by a change in material or surface (cobblestone for example). The lofted curve could then be allowed to intersect a much simpler wall form that provided a rough opening for the smoother arch loft. Now, if you need the archway to be flush with the rest of the wall you will need to use your method of just extruding it back. The shape used for this exrtusion should then be used as the path for the trim . Keep the path steps for the trim the same as the shape steps for the arch and the two should align. Remember also that you can use 3D Display to show the lofted arch mesh in the 3D Lofter for alignment purposes. >>Is it typical that you must segment (acad=break) all these nice arcs, either in autocad or 3ds, to have decent control over vertex location? if so…I can't wait for NURBS <g> Actually, every sgement in the 2D Shaper and 3D Lofter is a Bezier spline. When you add vertices by using segment/refine you're not breaking the spline – just adding detail where you need it. In general you should leave your AutoCAD model as pure, long arcs and adjust them in the 2D Shaper. This ensures htey're as smooth as ppossible and gives you the opportuinty to place the critical transiiton points exactly where you need them. – Phil
