Minimum Detail Size (mm)?
Details smaller than this get erased during tracing - a cleanup/aesthetic choice, not tied to what your printer can physically do. Raise it for a simpler result, lower it to keep finer detail.
Edge Softening
?
Smooths pixel-level noise before the black/white cutoff runs, so edges follow the real contour instead of jagged individual pixels.

Minimum Wall Thickness (mm)?
The thinnest wall you've confirmed prints reliably on your setup. This is a number you set yourself from your own testing, not something calculated - enforced as a floor whenever you set a shape's stroke thickness, and checked again at export.
Minimum Gap (mm)?
The smallest space your printer can leave between two separate features before they merge into one blob. A different number from wall thickness: a printer that lays a 0.3mm wall may still need 0.8mm of clearance. Two 0.5mm circles 0.6mm apart print as a peanut, not two circles. Used by Print Check.
Stroke Thickness (mm)?
Used automatically every time you invert a new shape. Still enforced against your minimum wall thickness above - you can always override an individual shape's thickness afterward in the toolbar.
Stroke Thickness (mm)?
Used automatically every time you invert a new shape. Still enforced against your minimum wall thickness above - you can always override an individual shape's thickness afterward in the toolbar.
Grid Spacing (mm)?
By default the grid auto-adjusts its spacing as you zoom, so it never gets too dense or too sparse to read. Uncheck Auto to fix it at an exact spacing of your own instead.

Fusion Scale Correction?
If Fusion imports the wrong size: divide the size you want by the size Fusion actually shows, and enter that number here. Then download again.
