Draw a cylinder - got a triangle on Flattened SVG

[MasterDimmy]

FreeCAD 0.18.4
LC interlocking last version till current date

I want to cut a circle diameter 10mm, hole 1mm, so i:

1. create body
2. create scetch
3. draw a circle 10mm and circle 1mm, connect to xyz center
4. create a pad 3mm of it
5. open lc interlocking
6. select pad
7. export
8. select shape2dview (it is still correct, 2 circles of 1 and 10mm)
9. save as Flatenned SVG
10. open it with any picture view software and got TRIANGLE!

It repeats constantly in 2 PC.

Probably you need to set Edit -> Preferences -> Import-Export -> SVG -> Max segment length for discretized arcs to a small non-zero value. Or export as DXF, which does not have that problem.
