I have several scenarios in which I receive errors using rotate_extrude() such as: ERROR: all points for rotate_extrude() must have the same X coordinate sign (range is -10.00 -> 0.50) I understand the error, what it means, and what causes it, but in most cases my model still displays in preview, and renders successfully, so I can still create my stl files & print it. But I am curious as to why, if this really is an error, it does not prevent the rest of my model from rendering (not that I want that to happen, since I am very happy with what does render). Is there a way to "disable" this error for certain parts of my code (since I know they will work)? I think that rotate_extrude() should not require all points to have the same sign (sort of like doing a rotate_extrude() for both sides). I am satisfied with what it does now, but since it does still display the error, I want to make sure that my code doesn't crash if the error does terminate it in a future update.

Why not clip the 2d geometry such as with right_half(planar=true) before rotate_extrude() to eliminate the error?

What library provides "right_half(planar=true)"?

It is a core routine same as rotate_extrude, no libraries needed.

>It is a core routine same as rotate_extrude, no libraries needed. My mistake. Larry is right, it is in BOSL2. I pretty much always have BOSL2 included in my scripts and sometimes lose track of what is in there versus the core.

I think you all misunderstood my question. My question is why is the rotate_extrude() not preventing the rest of my model from the previewer like all the other errors I see? Like I said, I am definitely happy that my model still works, I just think it is strange that this error does not act the same way other errors do.

I don't know the answer to your question. I assume there are potential problems with geometry spanning the axis of rotation such as generating faces with flipped normals. Such issues might not occur in every case but instead of relying on getting lucky it makes more sense to me to address the flagged problem.
