FredoCorner Size Limitation

I am trying to used FredoCorner to make a super complicated detail. I have blown up the piece I am working on to 120: 1 scale. (as in 9.5" turned into 95’) This is a good way to avoid a lot of the problems with sketchup not wanting to work with curves or in small dimensions. Do I have to scale it back down to use FredoCorner?

It keeps telling me that “Offset [7 1/4] is probably too large; Consider reducing it.”

My guess would be that the offset specified to FredoCorner would cause the resulting new edges to self-intersect because of a relatively small curvature in the path to be rounded (rather than the absolute scale of the geometry). Edited to clarify: if a large offset is specified to be applied to a path with small-radius curves, the resulting rounding will hit itself. Think of using a half-inch round-over bit in a router to follow around a corner that has a quarter-inch radius. As the bit shaves off material at the tight corner turn, it will overlap with freshly-cut areas on the upper inside of the newly-formed chamfer.

I have experienced the same error message on scaled up models - I just ignored it and there was no problem.

That might be a good guess. It is not a very curved edge.

I see it now. It does not like that it is running into another face it is not a self contained object. I guess I will have to use follow me or something.
