Sketching and extruding on curved surface

[Anonymous]

I have a slightly contoured surfacte that I would like to have a pattern of decorative milling lines on that follow the contour of the surface and that are a constant depth. I could use a flat, offset plane for the sketch, but I was wondering how to evely extrude from the sketch to the curved surface I want it projected onto. Is this even possible?

Hi @Anonymous,

Fusion today does not have a proper Wrap or Emboss feature.  If your surface is not too curved, you can get away with using Project Curve to Surface to map the curves from a planar sketch onto the curved surface.  Then you can use Split Face to split the face along those curves, and use Press/Pull to create a pseudo-Emboss on the curved surface.

I'll put together a little screencast showing how to do this.

Here is my pseudo-emboss workflow.  I skipped the Project Curve to Surface step in this one, because it wasn't strictly necessary.

Hope it helps

That looks like exactly what I needed. sorry it took so long for me to respond.

I was going to ask this question and you already answered it!  One thing though and I imagine you can extrude outward or away?

Hi Jeff, could you please help me with this? How can I do a "split face" of the whole sketch? I can only do it from a skecth. I'm new to Fusion 360. Saludos

@santituerca , unfortunately, you cannot do a split of the entire sketch - you have to do one loop at a time.  Further complicating things is that Fusion does not have a proper "wrap" capability.  The closest you can get is to use "closest point" mode in Project Curve to Surface.  So, in this video I:

1. create a new sketch
2. project curves to surface (this you can do all in one go)
3. use Split Faces to split one loop at a time (I only do 3 in the example)
4. (this is just to clean things up) - select and delete the split faces from the "back side"
5. use Press/Pull, in New Offset mode to emboss each shape into the cylinder

hope this helps
