DocProperties>Mesh page: render meshes regenerated even if Cancel is pressed

[Helvetosaur]

I am noticing that if I go to Doc Properties > Mesh just to check the current mesh settings - first it shows me the “Render mesh quality” page with Jagged, Smooth and Custom; if Custom is checked I hit the "Details button to see the custom settings. If I then hit the Cancel button without having changed anything, it still regenerates the display meshes for all visible objects - I see “Creating meshes… Press Esc to cancel” in the command line and if the meshes are dense, it takes a few seconds before finishing.

IMO, this is hooked up incorrectly, hitting the Cancel button should not do anything if I have not changed the setttings.

Hi Mitch - thanks, I’ll check it.
Can you verify? Here, I do not see any mesh created if I cancel, only on OK…

Hi Pascal,

It is happening at least with the file posted in this thread:

Odd render meshing with some extrusions and certain settings

Got a file from a client who was bewildered by the fact that his file size was huge and he didn’t understand why. I isolated a few of the elements that were causing this and they are in the file below, saved small (no meshes) - only 2.2 Mb for three extrusions. If I use Open to open the file, the render meshes will be regenerated, if you then save it back, you will see that the file size goes up to… 450Mb!! If you check out the render meshes, they are somewhere between 2 and 4 million polys …

As that file seems to have ‘problem’ objects, perhaps it’s just the file…

Wait, wrong button pressed… here’s the right video:

Nope, not just that file, here is a file with 1K cubes and a custom mesh setting:

1KCubes.zip (1.1 MB)

Also happens with just “smooth and slower” mesh settings - at least I thought it did - can’t reproduce now.

I’m just going to check in a minute, but try with extrusions and non-extrusions…

@pascal

but try with extrusions and non-extrusions

The file posted above (1K cubes) is 100% polysurfaces.

durn.

It appears to be happening only when one has a custom mesh set, but it actually does not seem to matter which settings are used…

[pascal (Pascal Golay)]

Hi Mitch - Here, using your file, once custom mesh is set with an OK (remeshes), reopening the dialog and cancelling does not churn out new meshes…

[Helvetosaur]

So what’s wrong with my installation???

[pascal (Pascal Golay)]

Yeah… just wondering about Bongo - seems unlikely, but what I’d normally say is, you know, disable non-default plug-ins, close, relaunch, and see…

-Pascal

[Helvetosaur]

OK, wow, I went to disable Bongo, just into Options>Plug-ins (not Mesh settings), disabled it and OK, then I got the meshes being recreated… And no, after a Rhino restart, disabling Bongo didn’t help. It looks like every time the Options dialog is closed, it re-meshes if I hit OK. No matter which page it was on. But not if I hit Cancel, remeshing only happens if I am on the Mesh page.
