Summary	0004638: cannot import name '_ViewProviderDimension' from 'Draft'
Description	Platform: Windows 10 Works with FreeCAD 0.18, not with FreeCAD 0.19 . FreeCAD 0.19's python reports "cannot import name '_ViewProviderDimension' from 'Draft' " .
Steps To Reproduce	Create two files: - test.scad: `text ("Hello", halign = "center", valign = "center", size = 6);` - test.py: `#!/usr/bin/python import FreeCAD import Part # This should read any type of file FreeCAD.loadFile("test.scad")` Then launch (on Windows), using FreeCAD's python: "c:\Program Files\FreeCAD 0.19\bin\python.exe" test.py Compare with FreeCAD 0.18 . "c:\Program Files\FreeCAD 0.18\bin\python.exe" test.py

Kunda1 2021-04-21 18:54 administrator ~0015636	This has been fixed in the 0.20 development version and should be backported to v0.19.2 (we don't have a date for that release yet). Closing ticket.
