P Retondo Posted January 14, 2003 Share Posted January 14, 2003 The trim tool does not work properly. Place a line over a polygon, and attempt to trim away a portion. An incorrect portion is often trimmed away, and the object being trimmed can sometimes just disappear. Quote Link to comment
MikeN Posted January 14, 2003 Share Posted January 14, 2003 I've found that the trim tool is basically for lines. Use 'Clip Surface' for trimming away segments of polys....much better. Quote Link to comment
P Retondo Posted January 14, 2003 Author Share Posted January 14, 2003 Thanks, runtime. I am pointing this out because the trim tool used to work (I'm talking about the tool, not the menu command), and doesn't anymore. I think it didn't work in version 9.5 either. It's a lot faster to trim a polygon with a line as opposed to drawing another polygon and clipping. Quote Link to comment
Herman Posted January 14, 2003 Share Posted January 14, 2003 use the "split tool" either by points or by line. Quote Link to comment
Guest Posted January 14, 2003 Share Posted January 14, 2003 P - Are you trimming an open or closed polygon? Is it a polyGON or polyLINE? Quote Link to comment
P Retondo Posted January 14, 2003 Author Share Posted January 14, 2003 Hi Katie, The problem occurs on closed polygons, and happens frequently. Quote Link to comment
Guest Posted January 15, 2003 Share Posted January 15, 2003 Can you send a simple or complex example of this to me, please? tech@nemetschek.net attn katie Make sure you note it's VW 10.0.1 in the email. Quote Link to comment
P Retondo Posted January 15, 2003 Author Share Posted January 15, 2003 Katie, In trying to recreate the problem for you, I think I discovered that it only occurs when one or both ends of the cutting line lie precisely on the boundary of the polygon to be cut. I'll send you an example. Quote Link to comment
P Retondo Posted January 15, 2003 Author Share Posted January 15, 2003 I take that back. I just sent you a second file where the line goes beyond the polygon boundaries, and the trim tool doesn't work. Quote Link to comment
Guest Posted January 15, 2003 Share Posted January 15, 2003 I have the files. I'll take a look at them as soon as I can. Quote Link to comment
Guest Posted January 21, 2003 Share Posted January 21, 2003 It looks like when the line used as the trim line intersects a 90d or right angle corner on a polygon, the trim doesn't know how to split that corner and deletes the entire polygon. This is currently being investigated as a bug. If you are trimming at a corner of a polyline that is other than a 90d corner, the trim line must extend PAST that corner point a few pixels in order to get the trim to work. Quote Link to comment
TiTaNiuM sAMuRai Posted January 22, 2003 Share Posted January 22, 2003 Please don't tell me that this is actually an unkown... I thought that the trim tool was designed to work on only certain things. I've noticed for half a year that certain things (e.g. polygons) can't be trimmed, but can be split.
