Hello

Sorry for this simple question, I've searched a lot and can't figure it out how It works.

a simple box, a simple face selection, and extrude along a curve, but the extrusion doesn't go along the curve and the Distance factor should be 1 but I need to crank it up to 3 and more.
please look at the picture.

It is confusing. What you need to do is:
1. Set extrusion distance to zero.
2. Set Spline shape to: Curve from second input
3. Set divisions high enough to follow your curve.
4. Enable 'Transform extruded front'
5. With point snapping enabled drag the front transform gizmo to snap to the end of your curve.

I don't think they could have made it any simpler (cough )

thank you Mike!
I know about this workflow and I use it.

but I believe the old workflow was like this:

- set extrusion to 1
- Set Spline shape to: Curve from second input
- Set divisions high enough to follow your curve.
more manageable right?


I'm trying to do a procedural extrusion with different curve lengths, so It is more convenient to do it this way. otherwise, I have to loop the curves and snap the transform to the tip of the curve.

My honest feeling is that the method you want to use is broken / bugged. I should have reported this, but haven't. I'll do so.

You'll see there is a video in the help docs where this seems to work - but in my informal analysis it only works for a specific case: when a straight line drawn between the start point and end point of the curve is normal to the extruded poly. Otherwise the extrusion is offset in angle as in your first image above.

I suggest you report this and I will do the same.
