Fill
Fills enclosed geometry with a pattern — lines, crosshatch grid, or concentric insets. Turns outline-only shapes into solid surfaces.

Parameters
pattern- Fill type: lines (parallel), grid (crosshatch), or concentric (inward offsets).
spacing (mm)- Distance between fill lines. Use nozzle width for solid fill, or wider for sparse infill.
angle (deg)- Fill line angle in degrees (lines and grid modes). Ignored for concentric.
How it works
Fill collects all closed geometry from its child blocks, then generates interior fill paths. The lines pattern creates parallel scanlines at the specified angle. Grid runs two perpendicular line passes (crosshatch). Concentric repeatedly offsets the boundary inward by the spacing amount until the shape collapses. The original outline is preserved — fill adds interior paths on top. Use spacing equal to your nozzle/line width for fully solid fill, or increase spacing for a lighter, faster infill.
