I am trialing Lightburn at the moment, but I am pulling my hair out importing my Inkscape SVG files. See below screenshot, I do a rectangle that is 30 x 3 mm
It is because of the line width in Inkscape. LightBurn is using the center of the line in the SVG (In lightBurn, lines do not have a width) Try making the line as narrow as you can in Inkscape
I’ll second G_O_M’s suggestion. I’ve noticed you’ll get different dimensions in Inkscape when using different line widths. I’ve taken to using 0.001 mm for the line widths, which are too thin to see, but using View, Display Mode, Outline, provides a visible line with a nearly zero line width. They translate to LB perfectly. One cannot use the dimensions in Inkscape with full certainty due to that aspect of the program.
Even if I create a rectangle of 20 mm x 20 mm, it will display dimensions of 20.001 on the tool bar.
Hmm ok, i took the extreme to make it visible on screen, but i usuallyl use .02mm with no fill and still get a variance.
Tried the .001 suggestion and it gets to a gnats leg difference which is better.
Thanks the tips.
Just tested, create shapes to desired size using fill and no stroke in InkScape, saved as SVG, produces exact same size shapes when opened in LightBurn.
