Now I've got 498 errors.

mainly unresolved external symbol
eg

__imp__Py_NegativeRefcount freecad-build-windows-12.5.4\src\GuiView3DViewerPy.obj FreeCADGui

Any help would be much appreciated.

I lied! :oops: I hadn't successfully configured in cmake! I missed the red warning regarding Pyside2 To fix that, I had to configure PYTHON to point to the version in the libpack and I had to add an additional entry for PYTHON_EXECUTABLE I'm now running build, its still got errors, but far fewer.

That's weird.

Creating two vertical tubes is something I've done in freecad many time without issue.

Could you post an image of your sketch. I suspect there's something odd within it.

I've been busy on other things so haven't built Freecad for a few months. I've fetched the most recent source, downloaded the latest Libpack (FreeCADLibs_12.5.4_x64_VC17), configured in Cmake (following a 'recipe' thats worked for me in the past) and apparently successfully generated the build files...

If it helps, things like this are quite easy.

Thank you for the suggestion, but if I set number of decimal places to (eg) 7, the rounding remains the same.

After many fruitless recompiling, I've finally proved which commit causes the cube and no doubt many other property errors greater than 1000mm ab247ac Seeing as my enthusiasm has been well and truly drained, I'll have a look tomorrow afternoon to see if I can get a fix without causing a regression ...

OK, I can narrow the commits down to 24719 to 24787 and looking through them, my attention is taken to the commits on April 20th with text 'handle small quantities in Property Editor', there's three of them.

Excellent! I'll have a look too.
