C3D-0140 · READ-ONLY: find a text-along-curve command [CMD-SCAN] error

Enumerates every registered command group and command name in the live session, reporting those whose name mentions TEXT, ARC, CURV or LABEL, to find the command that creates an SdskCurvedText entity. Draws nothing.

C# payload

// READ-ONLY. Enumerate every registered command whose name suggests text-on-a-curve, so the
// SdskCurvedText entity can be created via Ed.Command instead of the per-character workaround.
// Nothing is drawn.
Log("drawing: " + Db.Filename);
