C3D-0141 · READ-ONLY: find a text-along-curve command [CMD-SCAN-2] done

Lists loaded assemblies related to survey, express tools or land desktop, and reflects over every loaded type for CommandMethod attributes whose command name mentions TEXT, ARC, CURVE or LABEL, to find what creates an SdskCurvedText entity. Draws nothing.

C# payload

// READ-ONLY. Find a text-along-curve command. Runtime.Utils is not available in this host, so
// probe candidate command names directly: a defined command resolves via the "C:" lisp namespace
// or is reported by the ARX/DEFUN tables. Nothing is drawn.
Log("drawing: " + Db.Filename);

// Which arx/dbx modules are loaded - tells us if the Survey/curved-text module is present.
Log("=== loaded assemblies mentioning survey / express / land ===");

        || n.IndexOf("SDSK") >= 0 || n.IndexOf("AECC") >= 0)
        Log("   " + asm.GetName().Name);
}

// Test whether specific commands EXIST by asking the editor to look them up.
// Ed.GetCommandVersion / command echo is not available; use the documented approach of
// checking the command name against the registered command table via reflection on the
// CommandClass attributes of loaded assemblies.
