Hi all, I'm trying to find the least painful way of modeling something. Got an arched walkway supported by columns. The arch looks good. Had to keep shape steps up to 10 but it looks good. now I want to take the lines that make up the lower part of the arch and use that as a path for a trim piece that will be applied onto the arch face. So now I run into a two fold problem. In order to get the trim to follow the arch I have kept the steps up (10). But this puts a lot of steps in the horizontal trim also (^^^ area) _______ ______ ____| |______| |______(note vertical is actually curved.) ^^^ ! ^^^ I suppose I can 2d scale the extra vertices and weld them The other problem is at ! where the arch begins and ends I'm aware of the rescaling of the shape to compansate for the corner being turned (3D special effects book <g>) If I use a step of 10 the profiles bang into each other when lofted Somehow I need to pull the first interpolated step on the path away from the inflection point. I can only assume this means I must set my own vertices in the shaper for both the arch and trim path and set step to 0? If so what is the best way to station vertices along a curve? If I have snap on, refine the curve, is the vertex put at the snap point or at the math correct point for the curve data? Or should I loft the arch trim seperate from the horiz trim and try booleaning them? Hate to model something and then have the bool fail <g> Again ….Thanks for all the knowledge you guys keep providing. Todd
