Hi,
Learning VEX since a few days and I can't find a way to solve a simple polyextrude using VEX attributes.
As a sample I generate some polylines from scatter points. Then trying to extrude the polylines using VEX distance attribute values that I generate for each polyline.
For some reason the polyextrude doesn't work - it seems the polyextrude doesn't “read” the attribute..
I spent a lot of time trying to solve it without success. The file is very simple and pretty clear, any help will be very appreciated.
Thanks!

Hello,
it work if you make the attribute a point attribute
i know that with mesh it has to be a primitive attribute but as you are doing it on polyline …

here is the file

I think this should give you what you're looking for. On ramp_extrusion_values:
  • set “Run Over” to Points

On polyextrude1:
  • set “Extrusion Mode” to Points (and Existing for the second dropdown that appears when you set it to Points)
  • turn off “Ouput Back”
  • turn on “Output Front” and “Output Sides”

Understood. Thanks guys for the help.
I noticed Polyextrude Node with “Extrusion Mode” set to “Primitive/EdgeNormal” works well with Polygon curve. Is there any way to convert polyline to polygon curve?
