Summary0004133: Sometimes face / sketch exports to flattened svg or dxf incorrectly
DescriptionI've been seeing this bug very occasionally I believe since 0.16, seemingly at random. Trying to export a particular sketch as a flattened svg or dxf truly flattens the constituent paths such that they lie on top of each other when they should not. It may be that the paths are being projected along the wrong (90deg) axis to produce the exported vector image.
Trying to export a clone or facebinder of the relevant sketch then exporting produces the same results.
Steps To ReproduceOpen attached FCStd file, try to export Sketch002 as Flattened SVG or DXF. View exported file in Inkscape or similar, visually compare to original sketch.

For reference, Sketch001 exports fine. Rotating the body of Sketch002 by 90deg to lie parallel to the plane of Sketch001 does not solve the issue.

Tried in 0.17, 0.18, and 0.19 Daily with the same results.

Workaround is to pad the sketch, export the pad as a STEP file, open the STEP file in a new FreeCAD document, recreate the original sketch by tracing out the face using external geometry, then export the new sketch as SVG or DXF.

This workaround does not support sketches that cannot currently be padded, such as those which would produce multiple solids.

Yep, no worries, I'll make a forum post. I did see the yellow banner, but the text by the Description text field currently reads:
    
Read this before reporting and make a forum thread asking for help first if you aren't sure it's a bug!
I was pretty confident that this is a bug, so I posted without the forum thread. Perhaps the text could be changed if a forum post is always desired.
