Select All Sketch Segments Example (C++ COM)

This example shows how to use the IEnumSketchSegments interface to select all sketch segments in the active sketch. Nearly identical code could be used to also select all the sketch points in the active sketch by replacing IEnumSketchSegments with IEnumSketchPoints.



 hres = UserApp->getSWApp()->get_IActiveDoc(&pModelDoc);

 if (pModelDoc == NULL) return;



 hres = pModelDoc->IGetActiveSketch2(&pSketch);


 // No Active Sketch

 if (pSketch == NULL) return;    



 hres = pSketch->IEnumSketchSegments(&pSketchSegEnum);


 // No Sketch segments exist

 if (pSketchSegEnum == NULL) return; 


 int segNum = 0;


 long skReturned = -1

 hres = pSketchSegEnum->Next(1, &pSketchSegment, &skReturned);

 while (S_OK == hres)




  // Select the SketchSegment object

  hres = pSketchSegment->Select(TRUE, &ok); 


  if (!ok) AfxMessageBox (_T("Error Selecting Sketch Segment! Continuing..."));



  pSketchSegment = NULL;

  hres = pSketchSegEnum->Next(1, &pSketchSegment, &skReturned);



 if (pSketchSegEnum != NULL) pSketchSegEnum->Release();
