Hello,
I am using INKSCAPE for sewing pattern drawing. I need to use path outset for seam allowance. In INKSCAPE preferences I set "step/ inset/outset by" to 5mm. In document properties I have "scale x " set to 1.
Yet when I draw a circle , objecto to paht, duplicate and path outset, I have a second circle which is 15 mm away from the first circle.
I tried to close inkscape and reopen it in case the outset by whoulc not be applied before restart. Nothing changes. What do I do wrong?
thanks for your help.

Hi

Interesting! I can confirm the same behavior on my system as well.
I use Inkscape 0.92.3 (2405546, 2018-03-11) on Win10.

When I set the outset preferences to 5px (pixels) i get an offset of 5mm.

Might be an "undocumented feature" (bug) in the current version?

Try with units mm and scale set to 3.77953.

Probably the same bug I've been harping about for a year. Inkscape should "ship" with units set to pix and scale set to 1. Then you can change units to mm/in/pt/whatever without issue.
