Overhang

Overhang checks how far each part of a layer hangs out over the layer below. Colours come from the magma ramp: in the default class mode segments within the warning angle are deep purple, segments between the warning and the failure angle are red-orange, and segments beyond the failure angle are light orange; colorMode 1 instead colours every segment on a continuous magma ramp from 0° to the failure angle. The default angles of 25° and 45° are placeholders and should be measured for your material with a test print of a stepped cone. The global toggle chooses what the angle is measured from: off, the layer’s own normal (local, the layer-on-layer stagger); on, world Z (global, the lean against gravity). The two agree on planar layers and differ on conical ones. The component has a compute button.

Panel: 5 Analyze. Nickname: Overhang. Compute button: yes (runs only when the button is clicked).

Inputs

Name	Type	Default	Description
contours	Curve (tree)		Sliced contour tree from Slice or Place, one branch per layer, or per object and layer
warnDeg	Number	25	Warning threshold, deg from the build direction. The global input picks the local layer normal or world Z. Calibrate per material
failDeg	Number	45	Critical overhang angle in deg from the selected reference direction, calibrated for the material
tol	Number	0.5	Curve linearization tolerance, mm
colorMode	Integer	0	0 = classes (safe, warning and critical in magma hues), 1 = continuous magma ramp from 0° to failDeg, saturating above
global	Boolean	false	Use world Z for thresholds and colors when true, or the local layer normal when false

Optional group: CSV export input

Right-click the component to switch this group on. The inputs appear only while the group is enabled.

Name	Type	Description
csvPath	Text	Optional .csv file path for the summary per layer, written on compute

Outputs

Name	Type	Description
angles	Number (tree)	Local overhang angle per segment relative to the layer, deg, one branch per contour. Always the local reading, whatever global says
anglesWorld	Number (tree)	Global overhang angle per segment against world Z, deg. Always the global reading
summary	Text (list)	Summary per layer as CSV lines: max overhang and the percentage above each threshold. The percentages follow global
info	Text	Diagnostics
legend	Text	Legend definition text for Legend, matching the selected angle reference, thresholds and colors
colors	Colour (tree)	Color per segment in the active color mode and reference, cut like angles, for a custom preview
