Broken body?

[GeneFC]

A recompute of AngleBlade fixes the issue here.

Doh! I guess I should follow my own guidelines, for which the second step is to do a recompute. I thought I had done that earlier, but I guess not.

I just made several tests. Each is from reloaded file, mark feature for recompute, recompute:

I do not think that shows anything very useful. Nobody knows in advance where the unfinished solution might be. If the whole file rebuild works, don't worry about the others.

Shouldn't recompute Body invoke recompute Cylinder which fixes the issue? So why does recompute Body doesn't fix it?

As I said we simply do not know where the problem started. It could be something very early in the setup of the new model. One way to test would be to attempt to recreate the entire model completely from scratch. If the error is reproducible *then* it might be a subject for the experts to dig into.

I suspect that most users find weird things at times; I know I do. However, if a retry works then I simply attribute the weirdness to something I did wrong and move on.

At least before digging, design shall be free of any known trap that can weaken it. Eg. all sketches shall be properly constrained.

This is more for laughs Changing mapping of Cylinder while editing Polar feature or something like that produced this:

As many people discover, there is a large but finite number of ways to do things correctly.

There is an even larger, probably infinite, number of ways to screw up.

To me it seems that the AngelBlade file in the OP was saved when a Recompute was needed, but before the Recompute actually happened. The Force Recompute macro fixed the model for me, and after that I was able to make a PolarPattern from Pocket002 with Occurrences = 4 about either the Vertical Sketch Axis or the Base Z Axis.
