Your are using the iterator wrong. Try this:

AcDbObjectIterator *it = pPolying->vertexIterator(); if (it) { for (it->start(); !it->done(); it->step()) { AcDb3dPolylineVertex* pVertex = AcDb3dPolylineVertex::cast(it->entity()); if (pVertex) es = pVertex->setPosition(pt); // Don't delete pVertex! } delete it; // But delete the iterator when you are done with it }
