Fill spacing
Fill spacing is the distance between adjacent fill rows. Smaller spacing increases coverage and stitch count. The studio accepts 0.20–2.00 mm spacing, with the original Threadwork default of 0.42 mm. Fabric, thread and stabilizer affect which spacing is appropriate.
Tatami fill
Illustration mode creates alternating fill angles across thread layers. The Threadwork engine routes stitches through connected areas and uses jumps where it needs to travel to a disconnected object.
Underlay
The automatic illustration workflow includes crosshatch underlay from the supplied engine. Underlay can stabilize a filled area, but it does not eliminate the need for the right material setup. Photo mode uses a different fill treatment without this automatic underlay.
Jump stitches
A jump moves the needle between stitch locations without sewing the intermediate path. The Jumps view marks these movements in pink. The exporter inserts trims between separated objects where appropriate, but machine behavior varies.
Tie-in and tie-out
Short securing stitches are included at the start and end of layers. Their physical result depends on the embroidery machine and tension. Inspect the file in your machine software and test-sew.
The limits of a screen preview
The preview draws the generated stitch coordinates and color order. It does not simulate fabric stretch, thread thickness, needle deflection or machine-specific trimming behavior.
