Radial Dimension

Status: Implemented

Radial dimensions expose radii or diameters of cylindrical faces directly in PMI views. They support associative updates to revolved geometry, holes, and rounds.

Inputs

• annotationID – optional persistent identifier.
• decimals – numeric precision; inherits the PMI mode dimDecimals setting when left blank.
• cylindricalFaceRef – cylindrical face reference used to extract the centerline and radius.
• planeRef – optional face or datum that defines the projection plane.
• displayStyle – choose radius or diameter output.
• alignment – align leader projection to the current view or a principal axis.
• offset – shifts the label outward from the cylindrical surface; dragging the label updates the stored offset.
• isReference – formats the value as a reference dimension.

Behaviour

• Automatically computes center point, radial vector, and arrow geometry for both radius and diameter callouts.
• Maintains associative links to the source cylinder; machining edits update the PMI value on regen.
• Supports interactive label dragging on the projection plane while preserving trace lines and offsets.
• Center markers and arrows scale with screen space to stay readable while orbiting.

Usage Tips

• Supply a projection plane when the default view produces misleading offsets, especially for angled holes.
• Use diameter display style (Ø) for holes and radius display (R) for fillets to match common drawing conventions.
• Pair with linear dimensions to fully define hole patterns and bolt circles in a single PMI view.
