Problem: How do I create a note in a 3D model that is flush with the screen and has a leader
Example code used: Line 9 error

ProNote note;
status = ProSolidNoteCreate(mdl, NULL, pTextArray, &note);
ProNoteAttach noteAttach = nullptr;
status = ProNoteAttachAlloc(&noteAttach);
status = ProAnnotationplaneFlatToScreenCreate((ProSolid)mdl, PRO_B_FALSE, &plane);
status = ProNoteAttachPlaneSet(noteAttach, &annoPlane);
status = ProNoteAttachFreeSet(noteAttach,note_pos[0], note_pos[1], note_pos[2]);
status = ProNoteAttachAddend(noteAttach, selSurfaces[0], PRO_NOTE_ATT_NONE);
status = ProNotePlacementSet(&note, noteAttach);--------// return PRO_TK_BAD_CONTEXT-----------
status = ProNoteAttachRelease(&noteAttach);
status = ProAnnotationShow((ProAnnotation*)&note, NULL, NULL);
status = ProSolidRegenerate((ProSolid)mdl, PRO_REGEN_NO_FLAGS);
