Rookie Chamfer issues - Imported DXF from Illustrator

[bwgunner]

I am getting Chamfer errors in several places and I'm not sure what to do about them. 

Old-school Adobe junkie here dipping my toes in the 3D realm. I've created a laptop stand in Illustrator I like and have fabricated in the past from plywood.

I love this with full chamfers, but I can learn to love it with fewer if it's too hard. Right now I've done all the chamfers I can do on one piece, and left the other alone. Any ideas on how I can include the tail and head pieces? I get different results with different exports from Illustrator with no apparent logic. Sometimes the feathers chamfer, but not the spine. Sometimes the spine but not the head. It's wacky, and I'm sure I could set up the starting file better if I knew what I was looking for. 

Thanks!

You model is showing but it cannot be downloaded.  You probably have a Personal Fusion License which makes this impossible.  Please attach your model directly to an Forum reply.

If you do not know how to attach your Fusion 360 model follow these easy steps. Open the model in Fusion 360, select the File menu, then Export and save as a F3D or F3Z file to your hard drive. Then use the Attachments section, of a forum post, to attach it.

Depends on your output requirements.  If sending the non chamfered plate to CAM the chamfer, you will not run into the problem that you are seeing with the modelling Chamfer.

Modelling the Chamfer around sharp corners (the slots etc) should be no trouble.

Chamfers will misbehave where there are near tangency connections in the underlying sketch.  
Curve connections should be made Tangent.  
(Line to curve, curve to curve, and curve or line to Spline.)

Imported sketches are notorious for not following this requirement.

Might help….

Attached, thanks!

Planning to output as STL for 3D printing. Having little to no idea what I need to do for that, of course. 

So inside Fusion I need to select each line and make sure it is set to line, or spline, or curve? This seems like a basic operation I'm not familiar with. Do I need to clean up the model's components and relabel them? Sounds great, how?

Thanks folks!
