Issues rendering Arch labels in TechDraw view

[psadauskas]

I have a Arch plan with TechDraw page with a view of it. I have several Dimension labels, and those render fine. If I try to add a "Text" or "Label", however, it stops rendering the view in the page, and I get errors on the console.

Adding a "Label" gives me:

Code: Select all

16:00:19  DVS::onChanged - ��>j� - SVG for Symbol is not valid. See log.
16:00:19  Error - Could not load Symbol into SVG renderer for ArchView001

Adding a "Text" gives me:

Code: Select all

<class 'UnboundLocalError'>: local variable 'tstroke' referenced before assignment
16:04:51  Recompute failed! Please check report view.

To reproduce, open the file in FreeCAD 0.20, and in the tree view, drag any of the labels to the "New" group. Opening the file in FreeCAD 0.19 and doing the same works as expected.

Confirmed.

This recent commit is the cause I think:

If you try to add an Arch_Axis object to the "New" group there is an error as well:

Code: Select all

Indeed there were cases where this tstroke stayed undefined. With git commit e6b7c0e5f9 both errors should be fixed

Thanks.

Hello,

First of all, thank you for developping FreeCAD!

I have probably a similar Problem with Draft Label in Techdraw.

Adding a Draft_Label gives me:

Code: Select all

18:09:51  Cette fonction sera obsolète. Veuillez utiliser 'get_svg'.
18:09:51  DVS::onChanged - H�T$L�D$L�L$ SUVW�8 - SVG for Symbol is not valid. See log.
18:09:51  Error - Could not load Symbol into SVG renderer for DraftView

to reproduce the error :

Gui.activateWorkbench("BIMWorkbench")
### End command Std_Workbench
Gui.runCommand('Draft_Label',0)
_label_ = Draft.make_label(target_point=FreeCAD.Vector(-1700.9262594208005, -837.9066751926948, 178.25038011410697), placement=FreeCAD.Placement(FreeCAD.Vector(674.7998387378136, 2029.951927218433, 2028.8143436701757), FreeCAD.Rotation(0.44601488682286866, 0.11950894873610823, 0.229574936987557, 0.8567868344100226)), label_type='Custom', direction='Horizontal', distance=-1957.09865195767)
