Krass..let me show you a simple example about fillet in a situation with-without seam

A simple polyline 20x20mm:CENTER= corner filleted 10mm,RIGHT= corner filleted 10mm then REBUILDED



extrude now both:rebuilded curve on the left don't have seams,right curve show origin of the seams



now put two cylinders in a particular position





select both edge loops



Fillet both



Now you know,before fillet always check the area,if you detect seams crossing each other and so,rebuild surfaces avoiding that.

For further advanced situations check this:

Mauro - Interesting demo.

I would have thought the simpler polyline would give the least trouble.

Guess I have a lot to learn, especially regarding seams.

It would be helpful to know why seams get created in the first example, and not on the rebuilt curve. And why do seams interfere with fillet?

Hi Ed,

re:
> And why do seams interfere with fillet?

The filleter basically follows edges when it constructs fillet surfaces. The more complex the edge structure, the larger number of fillet segments have to be created and one of the things that tends to be difficult is dealing with the juncture areas where fillet pieces meet each other.
