3D dimensions in TechDraw

[run_the_race]

Referencing this thread:

Which ends in recommending opening an issue here fior discussion. Basically it seems like 3D dimension style was updated to the ISO standard way in 0.18, then there was regression in 0.19/0.20, as shown below:



Should I open a bug on the tracker, or is this an intentional change?

Good evening!
That seems like a lonog work around, not a long term solution.

Yes, an alternative / temporary solution because it is slow.

Okay, well thanks for providing a work around for in the mean time

Hi to everybody in the community,
I would point out again to the developers of TechDraw the different behavior in 3D dimensions using Freecad v018.x and v0.19.x

This can be considered a regression (at least according to many users, including me): it would help a lot to provide again the option to align the extension lines to the XYZ axes.
Even if the current v0.19 behavior was introduced to cover other user cases, this option could be made selectable in the property window

Please do not blame on me if this fix was already planned for a future release,
Rocco V.

This might be the commit to blame: git commit b75398d76345f3c88e09

QGIViewDimension is the class to handle dimension items in the graphic view and for ISO drawing there were used the functions findIsoDir and findIsoExt
See https://github.com/FreeCAD/FreeCAD/comm ... a9cf50L620

After the changes these functions are not used any more. Here the corresponding PR: https://github.com/FreeCAD/FreeCAD/pull/2552

unfortunately the corresponding issue https://tracker.freecad.org/view.php?id=0004687 has been closed.
Apparently there is a way to reproduce the desired result but I have not found anything.

Does anybody know how to get decent 3d dimensions?

Thank you!

Ok I found it, apparently a new feature in 0.21:
