C3D-0138 · READ-ONLY: inspect SdskCurvedText [SDSK-CURVEDTEXT] done

SdskCurvedText is a registered runtime class in this session. Reports its RXClass details and parent, searches every loaded assembly for a managed wrapper type for curved or arc-aligned text, and checks whether any such entity already exists in the drawing. Draws nothing.
