1. Linear Vertex - Help

Hello, Can someone please explain to me what a linear vertex is properly? I thought I understood it when I was initially trying with lines but once I applied the function on the grid, everything seems wrong. I understood it as, primvertex points to the point number, so vertex 2 of primitive 1 should return 2 but instead it is returning 6. Not sure why? The same function with lines give me the correct answer.
2. Run over parameter - Attribute Wrangle

Hi, can someone please explain to me, why we would set the run over parameter in a wrangle node to detail or points? What is the difference between these two? I know that run over points means that the vex code is run over each point in parallel, but what exactly is run over details? Thank you
3. Store and Restore Prims

Hi Everyone, i am new to houdini and i am looking for a solution in vex for that trivial problem: 1. create a grid 2. store the prims in a wrangle (primid, points assigned to primnum or whatever is needed to restore the topology) 3. use an add sop to delete all prims - keep points 4. restore prims in a wrangle - voila the grid is back i allready had a look at this and tried alot whitout no luck http://www.tokeru.com/cgwiki/index.php?title=Points_and_Verts_and_Prims#Store_point_order_of_prims_via_vex unfortunately, in this example he splits the prims before he stores them - i dont want this - there must be a solution with a loop going through the shared points and generating a new Prim from that. Maybe you can push me in the right direction.. Cheers Cruzifer maybe you can push me in the right direction
