C3D-0079 · READ-ONLY: find the curve label style behind the ARC/CHD/RAD labels [CURVE-STYLE-FIND] error

Identifies the style definition behind the four-line ARC/CHD/bearing/RAD curve labels so it can be recreated in another drawing: reports each curve label type, its style name and parent, and enumerates the parcel and general curve label style collections. No changes.

C# payload

// READ-ONLY. Find WHERE the curve label format lives so it can be recreated in another drawing.
//
// The four-line ARC/CHD/bearing/RAD label is an instance of a Civil label STYLE. What has to be
// captured is the style definition - its name, which style collection owns it, and the settings
// that produce the leader. Find the label, then name the style behind it.
//
// Read one curve label and report: its concrete type, its style name, and the owning collection.
// Nothing is modified.
