enter image description hereI am trying to create a gothic tracery window, and I've been trying to work from this tutorial https://youtu.be/vXAYt2h_Tto (skipping over anything to do with unwrapping/texturing as I do not need that for this piece) and I cannot seem to get the curve modifier to work no matter what I do... Half the time it won't apply to my curve, and the other half the time, it distorts it and none of the 'fixes' or changes I make seem to solve the problem..

I have been looking on every help post, YouTube troubleshooting tutorial, and thing I can find for days, I've checked normals, rotations, origins,I've re-drawn this a bunch of times and I have only been able to get it working one time, which of course was for nothing as blender crashed immediately after I was able to get it to work- so obviously I am doing something quite wrong and I just cannot seem to figure out what. I have attached a few screenshots of the usual result. Not entirely new to the concept of 3D drawing but quite new to Blender, and I've been trying so many different 'fixes' that I have lost track of all that I've even tried at this point so any suggestions are welcome! Thanks!

**Also should note: I figure this is possibly a large part of why I can't get it working, but I have been making my Arch (the curve I want to conform the trim to) by importing an SVG as a grease pencil, and converting it to a Bézier curve that I make a few adjustments (origin, rotation before converting to a curve, adjusting vertices after converting to a mesh, ect) and same with the Trim piece that I would like to conform to the curve. Does this have an effect the curve modifier?

Would be so grateful for any suggestions or insight! Thanks for reading.

  • $\begingroup$ Sounds like a lot of unnecessary steps. Why import as grease pencil instead of importing SVG directly? Why convert to mesh instead of keeping curve? Why not use a bevel object directly instead of deforming a mesh? $\endgroup$ Jun 29, 2022 at 19:16

To create a mesh of this type, you actually only need two curves:

  • A curve, which should be the profile (cross section) of your mesh.
  • A curve along which the profile should be applied.

So first select your arc. Then under Object Data Properties you will find the option to add a profile curve to create geometry with it.

Under Bevel you then simply add your profile curve.

Note: The profile curve must lie on the X/Y plane.
