Hi uffooo,
The attached dxf file, are created with LibreCAD 1.x or with QCad 2.x ?
These tree dimensions have inverted the "defpoints", codes 13,23 & 14,24 of AcDbAlignedDimension
I will try to write a patch to check the order of the points.
Attached a corrected dxf file (simply swapped 13,23 & 14,24 codes with cut&paste in text editor)
