martinalex Posted January 2, 2022 Share Posted January 2, 2022 Hi guys, I'm totally a noob at Houdini here. I want to ask that usually when I want to choose some edges from my model, I have this dotted point as if they are not connected. In this scene, I use a group node to choose the edges with delete non-selected, then I applied blast node, then sort node by Y, and used the add node after that. It solved the problem, but I feel that there's a better way to solve this problem. Does anyone know what's the possible cause of this problem? I will provide the hip file in the following attachment. The geometry node is called "big_pillar". Thanks in advance! Week 3.2.hip Quote Link to comment Share on other sites More sharing options...
Sepu Posted January 2, 2022 Share Posted January 2, 2022 I'll point you up to this thread Tomas explains this pretty well here. https://www.sidefx.com/forum/topic/70013/#post-297385 Anyway, if you want a to create a line from edge with one node, use the Labs_edge_Group_to Curve node from the Labs Quote Link to comment Share on other sites More sharing options...

This is what is causing display problems for example: the primitive is there in Shaded mode, but it cannot be displayed because it's degenerate. You can convince yourself of that by dropping a Carve SOP after this node; you will see that it's making a loop. You can however use it with by extending the group to the back of the geo, but this is really contrived at this point One easy solution would be: Boolean Shatter:surface / surface / generate AB-Seams, against a vertical grid..
