Original report text

Hello,

Example were padding do not work in prebuild 24212 Linux version but works on Windows, compiled from git 24489.
Test file in http://jhelmine.kapsi.fi/3D/LedKehysVaunuun_test.FCStd (same included to report also).

Additional information

Padding tested in:
FreeCAD_0.19-24212-Linux-Conda_glibc2.12-x86_64.AppImage
FreeCAD_0.19-23578-Linux-Conda_glibc2.12-x86_64.AppImage

Steps to reproduce

To repeat error open file LedKehysVaunuun_test.FCStd.
First use "Part Design" then activate Body001Yläpallo.
Click Sketch006RuuvinRunko and click Pad this sketch.
Padding to normal direction do not show anything else than outlines in already made body. Reverse direction padding adds structure.

Windows version (0.20 from master) works as expected and I can continue. Before error situation parameters in spreadsheet ("data") was changed and paddings and pockets removed. Changing data.PallonD (text "Pallon halkaisija") to small value like 50 or less makes error situation, multiple bodies. This was done before error but correcting to back do not help.

Per looo this looks like a discrepancy between OCCT 7.4.0 and 7.5.0

[adrianinsaval]

can reproduce here:

OS: Linux 5.16.8-arch1-1 (KDE/plasma)

but not here:

I don't believe this is a bundle issue, most likely an actual FreeCAD issue, possibly related to inverted faces, I can now reproduce in all of these:

Note that in my previous report I did not even test the appimage

[adrianinsaval]

aditionally the base shape is displayed differently depending on the pad length, very weird:

[adrianinsaval]

Also doesn't work on archlinux's 0.19.4:

OS: Linux 5.18.9-arch1-1 (KDE/plasma)

Coin version: 4.0.1
OCC version: 7.5.3
Locale: English/United Kingdom (en_GB)

Of all my test it only worked in the 0.19 flatpak when it used occt 7.3 so it could be a regression upstream

@adrianinsaval : can you retest it? For me it works flawless.

I add the file direct here.

I still experience this, might be fixed in occt 7.7.1, will try a version with 7.7.1 later today

Thanks. Note, that OCCT have created a 7.7.2 head, which means that in a certain time (normally some days) they release an update.

[adrianinsaval]

Indeed, works without issue with occt 7.7.1:

OS: KDE Flatpak runtime
Word size of FreeCAD: 64-bit
Version: 0.21.0.33439 (Git)
Build type: Release
Branch: (HEAD detached at 976ecb3)

[adrianinsaval]

I'll close the issue since this is an upstream issue so not actionable by us, and it's fixed upstream so it will eventually make it's way to our releases once we get full 7.7.1 compatibility

[luzpaz]

Maybe we should add this as a 'Known Issue' that is solved upstream ? (especially for the distros that don't keep OCC as up to date as we do?)

[adrianinsaval]

Where do we have such a list?

I think we use that for different general usage problems, mentioning specific opencascade coplanar-like problems seems like it will quickly fill the page with noise
