Cut depth and remaining web are linked. Minimum cut width is the narrowest groove your available tool can physically make (0 = no minimum). Manufacturing export is blocked if a required cut is narrower than that tool width, or if a segmented radius violates the land / cut-count limits.

Segments

Build the part as straight segments and separate segmented-radius bend segments
SegmentCut sideLength / referenceFinished angle / bendCalculated result
Straight segments carry their own length and sharp bend to the next straight. Segmented Radius is now its own segment between two straights, with its own bend angle, cut side and Inside/Outside radius reference.

Drawing Dimension Options
Adds a same-scale longitudinal side/front section beneath the Top view on the same drawing sheet. The side view only adds section-specific dimensions.
Choose which dimensions are shown on the third-angle flat-pattern drawing. Drawing dimensions use millimetres by default, so individual dimension values do not repeat the unit symbol.
The flat pattern appears when segments are available.
