Can't Additive Pipe a shape

Post by Steve76063 »

I've been trying to 'sweep' a shape around the outline of another shape (I actually did this on an older project). Now, whenever I select the small shape and select Additive Pipe, I immediately get a 'Recompute failed! Please check report view' error!
ps. I can do a Pad with the small shape, so I think it's a closed shape.

I'm not so much looking for someone to fix it for me, but I'd like to know just how to track down the cause of the error and fix it myself (so I can use that skill in the future).

Any enlightenment?

Excellent...I was selecting the shape, then hit Additive Pipe and hit the error.
Using your method, I selected the shape, Ctrl-selected a portion of the path, and got part of my sweep. Under Object, I selected another part of the sweep path and it filled it in all the way.
I'll have to remember your method - again, thanks.

This was discussed in the past (and I thought it had been fixed :? ): The error is a false positive, shown because you haven't selected a path yet. If you simply ignore it, and you select a path in the panel, then it works. I could understand a warning, but it is definitely no error, because there isn't anything really wrong yet.
If you would confirm the sweep without having selected a path, then of course an error should be shown.

This is indeed a regression. In this version ...

OCC version: 7.4.0

... I can select just a section and invoke the sweep without an error.

Thanks, that explains how I did a sweep before without seeing this 'error'...I was using 0.19.
