Thanks dezmo. Yes, I know how to use #followme with a face and an array of edges. Now I get the data (polyline points and bulges) that exported from AutoCAD. My colleague drew arcs in AutoCAD, and exported them as the data with information for generating pipe. My task is to draw the pipe in Sketchup. I already draw the pipe face, but do not know how to get the path from the data.
If I can convert the data to arcs in Sketchup, add_arc would be a solution.
Hi @Henry12 If you want to find the bulge you can use this formula bulge = Math.tan(( end_angle - start_angle)/4)
where start_angle and end_angle could found on the ArcCurve instance of an edge edge.curve.end_angle. In recreating the bulge take please take into consideration the direction of the bulge if it is left to right or right to left as it would produce the bulge the other way around (instead of pointing north it would point south)
