In the attached file, a ChamferEdge on the marked edge fails (I used with 1.5, but it fails with pretty much any value.). Finally I just extended the surface and BooleanSplit the corner off the block…
Thx,

Hi Mitch- I see it, thanks. The problem is that front face with the iso near the edge- it is a degree 1 srf with a knot inserted- if you remove that face and Cap the object, it all works OK. Not sure why the problem though with the srf that is there.
Also, works as is, but nearer the origin.
