Mr. Toni Klemm 0 Report post Posted March 10, 2015 Hello Everybody, Some questions regarding STL postprocessing. 1. Is there a functionality available to cut a trimesh by something different than a plane, a surface of revolution for instance? 2. After cutting a closed trimesh the body is open. Is there a way to extract the open edges as points? Toni Share this post Link to post Share on other sites
Karsten Wenzke 12 Report post Posted March 10, 2015 Hey Toni, 1) There is no post processor to cut a trimesh with a surface at the moment. 2) It is possible and I have already a Feature Definition finished, but it is very slow...Therefore I will ask some of my colleagues tomorrow. Cheers, Karsten Share this post Link to post Share on other sites

Karsten Wenzke 12 Report post Posted March 11, 2015 Hey Toni, I have created a feature which derives the points of an intersecting face of two solids.I tried to comment all steps of the feature.The feature inputs are a difference and an intersection.The outputs arean objectlist which contains all points of the intersecting surfacean offset and a bsplinecurveA small note: If the solids have a high number of points than it might take 30-60 sec until the feature is finished.Therefore while testing the feature start with small solid with less than 200 points. An idea for cutting your trimesh with the surface is:create a trimesh of your surface use the extrude to plane postprocessor create a new solid for the difference the source should be Surfacetrimesh - originalTrimesh and for the intersection a "*" between set the intersection and difference for the feature arguments see the result :-)I've added an example how to intersect a Brep with a surface. Maybe it is worth a try to build your geometry with brep. If you have any question I am happy to help you.
