Emboss: selecting & assigning materials

[david_feldmanFBCUV]

I'm relatively new to Fusion here, and can't figure out how to do something that I would expect to be easy. I've attached a screenshot of the project, which is a 3D-printed container for some letter tiles for a game.

The raised lines above the letters need to be in a different material (filament) from the main body of the container. They run along a curved surface so I can't just sketch and Extrude. Emboss works well here for the geometry, but then I run into a problem: I can't find a way to easily select the embossed geometry to assign a material to it, short of dragging the material onto one face at a time. I'd expect to be able to do any of the following:

1. Define a Selection Set and apply the material to it. I can define the Selection Set but as far as I can tell there's no way to use it when applying materials.
2. Project the sketch onto the relevant faces and then Extrude to a new body.
3. Tell Emboss to generate a new body.
4. Select the newly-embossed geometry and easily separate it from the main body. (This is technically possible but then involves a bunch of work closing holes.)

Some version of this issue (identifying/separating pieces of geometry when the separation involves more than a planar surface or single face) keeps coming up for me and I've not found an answer. What am I missing?

Thanks!

If you still can't figure it out - 

Can you File>Export your *.f3d file to your local drive and then Attach it here to a Reply?

@g-andresen This worked perfectly, thank you! Quick summary for anyone else who stumbles on this thread:

1. Before you do your Emboss (or rewind the timeline), go to Surface → Create → Offset.
   1. Select the face(s) at which you'll want to separate (i.e., those on which the new geometry will be embossed).
   2. Offset by 0, creating a new body with a copy of those faces.
2. Hide the new body if necessary.
3. Emboss as before.
4. Solid → Modify → Split Body
   1. Body to Split: The original body (with newly-embossed geometry)
   2. Splitting Tool: The new body
5. Done.

I need to do something very slightly different, namely I want the debossed form. I need the characters to be a separate object that I can assign a different filament color to, so it fills in the characters but leaves the upper surface smooth. The split Body doesn't seem to handle this case.

Hi,

something like this?

Here is another variation on @g-andresen technique...

Thank you! I thought I had to do a Paste New to make an independent copy, and that option wasn't there.

I hadn't realized that bodies can be copied and pasted like normal! That will help now and then.

Problem solved!

Thank you!

I really appreciate your explanation, and good ideas!
