How To Save A Drawing Thru Proxy Object

Yes, dwgOutFields() will only save the objects data, not the class type information. I suppose this is taken from the virtual methods declared and implemented by the ACRX_DEFINE_MEMBERS / ACRX_DECLARE_MEMBERS macros. And so you would have a hard fourth dimension to change this.

Yous could endeavor to use an AcEditorReactor and implementbeginSave() and saveComplete(). In beginSave() you supplant your objects with a temporary base-form clone and in saveComplete() you switch back. To do this yous can use AcDbObject::handOverTo():

          class MyEdReact : public AcEditorReactor { public: 	virtual void beginSave(AcDbDatabase *db, const ACHAR* pIntendedName) 	{ 		AcDbObjectIdArray allMyPlines; 		getAllMyPlines(db, allMyPlines); //            Write this yourself!                        int i, nCount = allMyPlines.length(); 		Acad::ErrorStatus es; 		AcDbPolyline *pline = 0; 		for (i = 0; i < nCount; ++i) 		{ 			if ((es = acdbOpenObject(pline, allMyPlines[i], AcDb::kForWrite)) == Acad::eOk) 			{ 				AcDbPolyline *plineTemp = static_cast<AcDbPolyline*>(pline->AcDbPolyline::clone()); 				// plineTemp->setColorIndex(1); // Merely            my            test 				es = pline->handOverTo(plineTemp); 				if (es == Acad::eObjectToBeDeleted) 				{ 					m_TempPlines.append(plineTemp->objectId()); 					m_ReplacedPlines.append(pline); // don't close pLine. Store it for later 					plineTemp->shut();             // but this 				} 				else 				{ 					delete plineTemp; // failed 					pline->close(); 				} 			} 		} 	}  	virtual void saveComplete(AcDbDatabase*, const ACHAR* pActualName) 	{ 		Acad::ErrorStatus es; 		int i, nCount = m_ReplacedPlines.length(); 		for (i = 0; i<nCount; ++i) 		{ 			AcDbPolyline *pline = 0; 			AcDbPolyline *plineBackup = 0; 			if ( (es=acdbOpenObject(pline, m_TempPlines[i], AcDb::kForWrite)) == Acad::eOk ) 			{ 				plineBackup = static_cast<AcDbPolyline*>(m_ReplacedPlines[i]); 				es = pline->handOverTo(plineBackup); 				if (es == Acad::eObjectToBeDeleted) 				{ 					delete pline; 					plineBackup; 				} 				else 					pline->close(); // failed 			} 		} 		m_ReplacedPlines.setLogicalLength(0); 		m_TempPlines.setLogicalLength(0); 	}  private: 	AcDbVoidPtrArray m_ReplacedPlines; 	AcDbObjectIdArray m_TempPlines; };        

By the way: Do yous know the AcRxOverrule classes? If you want to create portable DWGs, yous should consider to stay with the build-in classes, add your awarding data as XData, XRecord or whatsoever and apply an appropriateAcRxOverrule if you want custom behaviour.
