I sent it to George, and he reports that it works for him. This month's solution is PLINE-3D-2D.LSP. Several routines he downloaded from the Internet claimed to perform this function, but all failed to set the z coordinate to zero. Autocad 3d Polyline To Polyline Draw Longsection From 3d Polyline Lisp To SayĬonvert 3D Polylines to 2D 1 Sep, 2003 By: AutoLISP Solutions: See how Visual LISP saves serious coding time.George Anderson of Eugene, Oregon, e-mailed a request to turn 3D polylines into 2D polylines. You can create annotations in several ways - either at each vertex of the polyline (Source) or at a fixed regular distance (Interpolate) along polyline, or both Source and Interpolate. In addition, there are options to create named sections, segmental distance annotation, X and Y coordinates annotation as well.The What to annotate section determines the points along the 3d polyline where the profile annotation is done. The elevation values (heights) are displayed along the Y axis while the chainages (distances) are displayed along the X axis. The GTPROFILE command is used to create cross-sectional (longitudinal) profiles from 3d polylines. Draw Longsection From 3d Polyline Lisp To Say.
