QCAD Professional
Win installer 32bit
Version: 3.25.2.7 (3.25.2.7)
Internet: QCAD.org
Build Date: Dec 16 2020
Revision: e06f230
Qt Version: 5.13.2
Architecture: i386
Compiler: Unknown

Follow up on: FS#2023
The zero crossing at 180° turn is fixed.

Found two very minute Line segments where the Width is set zero.
Revision dxf included.

Referring to the grid they are rendered about 0.0002 long.
They are in the order of 5e-15 and less or simply zero long in this case (<1ULP).
Results may vary in length ... and vary after Save/Revert.
Files included: PolyWidthErrLargeArc_v2.csv (a/b)

Not encountered on a Polyline with line segments.

Regards,

The newer explode functionality for Polylines with widths (Sep 11, 2020)
doesn't exclude null length Lines nor polys.

The simple method excludes shape lengths < 1.0e-5
