Polyline Diet CAD Tips. Updated in September 2. It has come to the authors attention that the routine fails if there are coincident vertices at the beginning of a polyline. The new file accounts for that possibility. Kent Cooper, with help from others, put together a fairly complex LISP routine used for weeding vertices from polylines. Autocad 3D Polyline To Lwpolyline' title='Autocad 3D Polyline To Lwpolyline' />There are various polyline types in AutoCAD, the most common of which is usually the LWPolyline lightweight polyline. It can be confusing because the LWPolyline. AFAIK, the PLINE command generates the 2D Polyline technically called LWPolyline and as the name indicates, it can be drawn only in 2D. That means, suppose you are. C4F9F74C1AC41?v=1.0' alt='Autocad 3D Polyline To Lwpolyline' title='Autocad 3D Polyline To Lwpolyline' />Only the code is complex, however using this routine is a breeze. Load the LISP file and start the command by entering PLD at the command line. The routine works by eliminating extra polyline vertices based on the distance and angle between them. Extra vertices on collinear segments are deleted regardless of distance, and you have the choice of whether or not to straighten arc segments. Note that this routine only works on LWpolyline entities. Cadalyst tips WEED and WEED2 work on the older heavy polylines. Nice job with good comments, and credit is given to others who helped with this code.
