Properties

cutLines

cutLines: Vec3[][]

Section cut edges where the cutting plane intersects geometry.

featureEdges

featureEdges: Vec3[][]

Feature edges (creases, folds).

hiddenLines

hiddenLines: Vec3[][]

Hidden geometry lines (occluded by other geometry).

outlineHidden

outlineHidden: Vec3[][]

Hidden outline edges for non-structural elements.

outlineVisible

outlineVisible: Vec3[][]

Visible outline edges for non-structural elements.

silhouettesHidden

silhouettesHidden: Vec3[][]

Occluded silhouette / apparent-contour traces — style like hiddenLines.

silhouettesVisible

silhouettesVisible: Vec3[][]

Visible silhouette / apparent-contour traces. Split from the hidden half so renderers can honour drafting convention — an occluded contour must be able to draw dashed, not inherit the visible outline's heavy solid stroke.

stairArrows

stairArrows: Vec3[][]

Directional arrows for stairs and ramps.

visibleLines

visibleLines: Vec3[][]

Visible geometry lines (non-occluded).
