Hi,
QCAD is a 2D program! Your drawing contains 3D entities what leads understandably to unexpected behavior in QCAD.
If you flatten it to 2D (Menu/Misc/Modify), change the Dim settings from Arrow to Tick, reduce the size of the DIM text from 3 to 2.25, remove the double dimensioning then … it will work just fine in QCAD. ![]()
