Great instruction, thanks. Object mode, I assign bevel modifier, bevel does not respond, I move on to limit method, back to edit, select, increase bevel weight, no response. Workaround, scaling in bevels manually.
In the Bevel Modifier, under Geometry, disable Clamp Overlap. That should get it working. (It already works, but you can't see it, because some Edges are too small, so the Bevel is clamped too soon.)
