Rounding angles < 90° with predetermined radius - Professional

@jwr.rom, thanks for the instance.
I believe I see what the issue is. In my instance above I had solely edges for SketchUp to take care of, not 100% like what you’re employed with.
In your instance SketchUp wants to mix ‘“tangent” with one edge and one final phase of an arc.

Cut up of the final phase of your arc by drawing a short lived edge from the final however one endpoint.
Then explode that separate final endpoint (which remains to be an arc). now you might have two edges operating to a mutual endpoint and the operation sick work on sharp edges.

Then delete that briefly drawn edge.

So in brief, the issue isn’t (sharp) angles. The issue is making an attempt to attract tangent to an edge and a phase of an arc.

I waited for this affirmation

with arc (or exploded arc)

with line

I made the primary video from the earlier publish with traces as an alternative of the arc/exploded arc, that’s why I put the icon

You may as well prolong a line from the following to final level of the arc previous the intersection, double click on to create the fillet, and delete the surplus geometry by hand. Your technique routinely deletes undesirable geometry which is extra environment friendly.

I can do two corners directly. However then there are additionally the additional steps to blow up these separated “one phase” arcs. I’ll should examine your technique to see if that explodes the final arc phase immediately. That might be extra/equally environment friendly for rounding only one nook at a time.

Not less than we now know what the issue was.
