Ocelote Posted September 11, 2017 Share Posted September 11, 2017 (edited) Hi guys, I wonder if there is a way of selecting some of the edges of a grid I have based on the intersection of those edges with a curve on the same plane.... Hope it's clear, but if not, here is an image for better understanding. Thanks in advance!!!

Noobini Posted September 11, 2017 Share Posted September 11, 2017 got something close...seems if the intersection is too far from the edge centre...it won't pick it up...but if your cutting line cuts it near the centre of the edges most of the time...it might just work... vu_EdgeCurveIntersection.hipnc Quote Link to comment Share on other sites More sharing options...
Noobini Posted September 12, 2017 Share Posted September 12, 2017 (edited) here you are, works for all cases now (even works with curve on curve instead of curve on grid). I have no idea why the viewport display is flaky...the Polywire proves it works...yet group Promote doesn't wanna display nicely......dunno... vu_EdgeCurveIntersections2.hipnc Edited September 12, 2017 by Noobini Quote Link to comment Share on other sites More sharing options...
konstantin magnus Posted September 12, 2017 Share Posted September 12, 2017 You can also use the sourceprim attribute from the intersectionanalysis node. intersect.hipnc 1 Quote Link to comment Share on other sites More sharing options...
Noobini Posted September 12, 2017 Share Posted September 12, 2017 i DID try that, I tried to examine the Geo Spreadsheet to see what it gives me...but couldn't quite make heads or tails of the data...have to have another look.... Quote Link to comment Share on other sites More sharing options...
konstantin magnus Posted September 12, 2017 Share Posted September 12, 2017 Sourceprim contains first the number of the primitive the curve has cut at that point and second the primitive number of the curve responsible for cutting. Quote Link to comment Share on other sites More sharing options...
Ocelote Posted September 12, 2017 Author Share Posted September 12, 2017 Wow, thanks a lot guys! I'll dive into your solutions as soon as finish my work. Noobini and Konstantin Magnus you were so kind, I really appreciate it. Quote Link to comment Share on other sites More sharing options...
