Different width of the Chamfer after Boolean operations

Hello! Have a problem with continues chamfer on the edges after Boolean operation. On the screen you can see the different width, can't solve it for days, the only way I found is to create first chamfer shape (3rd screen) with Loft and after vertical edges will Chamfer ok, but it is a very tedious way. I tried to connect vertices on 2nd screen with Bridge Curve, but Chamfer is not considering it either.
Thank you for any help!

Hey @alexander_novikov722,
I can think of using a loft to do this: https://cad.onshape.com/documents/6602bfbd29c639087a03c5d2/w/4569d2862c0c11e3125f8d5d/e/c4a52348ffb88993febf35f6
Hello today encountered the same problem, is it possible to chamfer on top of chamfer or not in onshape?
Any reason your not doing all three chamfers in the same feature?
In my experience, it has never been a good idea to apply a chamfer which completely removes an adjacent face, like in this case. That only means asking for trouble downstream.
Anyway, in this case, the chamfer only APPEARS to be a different width, while it is mathematically correct and the same width: The chamfer at the angled 'pyramid' part has the same distance to the original edge like the others. It is only not measured in any of the orthogonal directions, but perpendicularily to the reference edge, which is at an angle, in this case. To math the two visually , we'd need in fact different width chamfers!
Since Onshape has no chamfer by width or chamfer up to boundary curve, we'll have to do this one manually.

You could use a "move face" to adjust the chamfered face after the fact.
Or you could use a face blend to apply a chamfer defined by width but that might be more trouble than it's worth…
Another option would be to sweep a cutting profile along the chain of edges.
