Profile From Data Points (Tip #2140) by Pedro Ferreira is a civil engineering power tool that generates a cut section along a path as defined by a polyline through a cloud of points. An example drawing is provided with the LISP function for you to try. The data points are 3D and are collected automatically based on the layer name. A polyline represents the XY path through the points. When finished (it could take a few seconds or even minutes depending on your computer power), it draws a profile section. You can exaggerate the Z scale of the profile or just use the default value of one. This is some fine number crunching! |
