Fillet on boolean joins?

john_orr457

I have a complex shape created using a boolean subtract and cannot fillet the edges where the two original objects meet.  Is this expected behavior? Anyone know a work-around so I can fillet those edges?

The entities in Sketch 2 are not lined up causing a small step at the bottom of the J-hook. I would consider re-sketching one j-hook with only the outer profile (not overlapping geometry, with dimensions and correct constraints) - then use extrude remove (rather than extrude new and boolean subtract after) - then pattern the j-hook across the other side.

John,

Can you make your document public and share the link here? If not, maybe post a picture of the area in question.

I would try making a 0.05" radius (or something small relative to your project) Fillet and seeing if that works.

Let us know!

Best,

Jason

Sorry for the delay.  Here it is. I can get none of the corners in the j-hook areas of Part 1 to fillet.

Yep!  That worked great! On to Shapeways!
