Saving facets created using Convex Hull and memorized selections

General discussion
1

Hello and thanks for the great support so far.

I created a number of facets using the Vertex->Create Facet from Selected->Convex Hull. That worked fine and I saved the file, but when I read the file back in, it would seem that the newly created facets were no longer there. Also all the created facets were memorized using Selection->Memorize selection to, but the memorized selection was also not saved. Have I made a mistake?

I am currently using version 2.8.7.

Thanks
Chris

Hello Chris,

Is it a one-off or is it reproducible?
Are you sure that it wasn’t a file saving error (maybe the timestamp could tell that the file wasn’t saved, after all)?

I tried now (on my home Mac, not on Windows though), and it worked as expected with 2.8.7:

Hello Marton,
Thanks for the video. I tried it myself and it worked with simple test example. After a little further work, I see for my initial problem, there is a message which says:
1 null polygon(s) found !
These polygons have all vertices in a single line, thus they do nothing !
Delete them ?

If I click OK, the newly created facet is removed (it is circular). However, if I click cancel, the facet is still there - so I guess I should just click cancel - but it seems that the message in the dialog box isn’t quite right ?

Best Wishes
Chris

This is interesting, as the facet you manually created should NOT be identified as NULL.
I recently changed the detection threshold, and maybe it’s a bug.
Could you please attach here the file with the facet that pops up the message?
I’ll check the code why it’s misidentified.
Thank you very much, Marton

Hi Marton, Attached is a simplified version of my model. The circular features were previously turned into facets.

Many thanks for noticing and reporting this.
As suspected, this was caused by a faulty collienarity detection condition.
I’ve fixed it and released 2.8.8, if you encounter the bug again, let me know.
Cheers, Marton

Hi Marton,
If I click on the download link from the webpage, it still seems to download version 2.8.7.

Thanks

Indeed, I made a copy-paste mistake, but thankfully you caught it right away :slight_smile: Fixed now!
