I need to extrude edge loop called "contour_01" I create a group "contour_01" then i remesh this circle form then i specify "contour_01" edges in polyextrude node and try to move distance button and get nothing...
I need to extrude up this group "contour_01"
Just learning...

Why is "remesh" done after the "group", isn't it disrupting the "group" ?

juejuezi disrupting
Yes - i check it out and yes - it's my bad!!! Nonetheless the task continues to exist - as you can see on video - i make a group = outer-edge-loop and i wanna extrude it up to may a cylinder but changing distance in polyextrude - edges move away from center to outness but not up direction
Yes - i understand that i can use "transform extruded front" - but it is not what i need - i need real - true extrusion. What am i to do to extrude my outer-edge-loop in up direction?

Have you tried extrusion mode with point normal?

point wrangle after remesh1 ``` v@pexN = {0,-1,0}; ```
and then poly extrude : Extrusion mode - Point Normal - Attribute - "pexN"

Yes!!! The solution - thanks.
As i understand that i can direct extrusion tawards normals then there appear a question: what node allow my control normal direction? (not vex pls)

juejuezi poly extrude : Extrusion mode - Point Normal - Attribute - "pexN"
I couldn't reproduce your method - any suggestion??
PS I just begin to learn houdini

The input box does not need to be green. You should (Ctrl + Shift + Left Click) on this input box to make it black
The input content is "pexN", not "@pexN", I use pexN instead of N just to not occupy N, because the original N will still be useful in the future and I don't want to overwrite the value
"poly frame" ,"orientalongcurve" ,"normal" nodes can control normal direction
For your current needs, using Vex to control normal is better

You can also use attribute transfer node to get normals from another geometry. But as juejuezi mentioned, in fact it can be any vector attribute and VEX has many advantages doing this (creating, manipulating etc ...).

Thanks for detail help!
But pressing (ctrl+shift+left click) destroy result comletely After pressing the field got black color and changing parameter leads only to the previous result After pressing (ctrl+shift+left click) on green field with pexN-parameter - all dissapeared I'm discouraged - nothing changed!
But if to choose extrusion mode/point normal then all works good
""poly frame" ,"orientalongcurve" ,"normal" nodes can control normal direction" -------------- interesting information!!!

Yes, - you are right but i just begin to learn houdini and can't allow to myself to use vex

Extrusion mode - Point Normal - Attribute - "pexN"
Not Distance - "pexN"

All works!!! Thanks!
