Visualization

Engrave regions render through a shader that draws scanlines in world space at your actual line interval and scan angle — change the spacing or angle in Operation parameters and the fill updates in real time, with cross-hatch showing its second pass at 90 degrees. Preview lines are a fixed 0.001 in wide for a laser-like density, so 100 LPI looks like 100 LPI, not a cartoon. Overlays respect the operation enable toggle, and mixed cut/engrave parts stack the fill correctly using even-odd nesting (see Cut vs engrave).

After generation, cut toolpaths draw in green with direction arrows, lead-ins in blue, lead-outs in red, and rapids as dashed grey lines — the same language as Plasma. Engrave operations would be unreadable (and slow) drawn row by row, so the overlay summarizes each engrave sequence as a bounding box with its entry and exit points: one box per region when the fill link mode is shapes-individually, one box per operation when it's all-shapes-once. You can see the machine's travel order at a glance without rendering ten thousand scanlines.

Locked parts render in the standard locked colors, disabled operations grey out just their layer's geometry, and parts that collide or fall outside the sheet turn red and are auto-selected after generation — identical styling to Plasma, so nothing needs relearning between workspaces.
