QCAD Professional
Win installer 32bit
Version: (
Internet: QCAD.org
Build Date: Nov 18 2020
Revision: 40f4475

Architecture: i386
Compiler: Unknown

Most likely not related to the QCAD version, rather an old sore.

Confirmed by ‘cccplex’ Linux ‘Latest Ubuntu’

Polyline arcs with Width = 2R render as circle segments rather than circle sectors.
As Non-reversed arcs these don’t explode.
As reversed arc these explode to a single arc rather than a circle sector contour.

There is also still the faulty rendering with Z not zero
