Finding the Active Viewports in Model Space
1 // Set some viewport information. 2 AcDbViewportTable* pViewportTable; 3 if (db.getViewportTable(pViewportTable, AcDb::kForRead) 4 == Acad::eOk) 5 { 6 // Find the first viewport and open it for write. 7 AcDbViewportTableRecord *pRecord; 8 if (pViewportTable->getAt( 9 "*ACTIVE", pRecord, 10 AcDb::kForWrite) == Acad::eOk) 11 { 12 pRecord->setCenterPoint(AcGePoint2d(0.5, 0.5)); 13 pRecord->setHeight(1.0); 14 pRecord->setWidth(1.0); 15 pRecord->close(); 16 } 17 pViewportTable->close(); 18 }
1改变实体颜色
1 Acad::ErrorStatus changeColor(AcDbObjectId entId, Adesk::UInt16 newColor) 2 { 3 AcDbEntity *pEntity; 4 acdbOpenObject(pEntity, entId, 5 AcDb::kForWrite); 6 7 pEntity->setColorIndex(newColor); 8 pEntity->close(); 9 10 return Acad::eOk; 11 }
2打开model空间
1 bool OpenWorkingModelSpace() 2 { 3 Acad::ErrorStatus es ; 4 AcDbBlockTable *pBlockTbl ; 5 AcDbBlockTableRecord *pp ; 6 //AcDbObjectId pObjectid; 7 8 // Get the block table 9 if ( (es =acdbHostApplicationServices ()->workingDatabase ()->getBlockTable (pBlockTbl, AcDb::kForRead)) != Acad::eOk ) 10 { 11 acutPrintf ("\nCouldn't open the block table!") ; 12 return false; 13 } 14 // Get the Model Space record and open it for read. 15 if ( (es =pBlockTbl->getAt (ACDB_MODEL_SPACE, pp, AcDb::kForWrite)) != Acad::eOk ) 16 { 17 acutPrintf ("\nCouldn't get Model Space! Drawing corrupt.\n") ; 18 pBlockTbl->close () ; 19 return false; 20 } 21 pBlockTbl->close (); 22 //pp即为model的指针 23 //使用pp 24 pp->close(); 25 return true; 26 }
3创建textstyle
1 bool CreateTextStyle() 2 { 3 Acad::ErrorStatus es; 4 AcDbTextStyleTable * pTextStyleTable; 5 es= acdbHostApplicationServices()->workingDatabase()->getSymbolTable(pTextStyleTable, AcDb::kForWrite); 6 if (es != Acad::eOk) 7 { 8 delete pTextStyleTable; 9 return false; 10 } 11 if(pTextStyleTable->has("textstyle name")) 12 { 13 //delete pTextStyleRecord; 14 pTextStyleTable->close(); 15 return true; 16 } 17 AcDbTextStyleTableRecord * pTextStyleRecord = new AcDbTextStyleTableRecord(); 18 if (pTextStyleRecord == NULL) 19 return false; 20 21 22 es = pTextStyleRecord->setName("Mytablestyle"); 23 //es = pTextStyleRecord->setFont("@宋体",Adesk::kFalse,Adesk::kFalse,936,FIXED_PITCH ); 24 es = pTextStyleRecord->setBigFontFileName("gbcbig.shx"); 25 es = pTextStyleRecord->setFileName("txt.shx"); 26 //es = pTextStyleRecord->setTextSize(2.2); 27 //设置属性 28 if (es != Acad::eOk) 29 { 30 delete pTextStyleRecord; 31 return false; 32 } 33 es = pTextStyleTable->add(pTextStyleRecord); 34 if (es != Acad::eOk) 35 { 36 acutPrintf("not add id"); 37 delete pTextStyleRecord; 38 return false; 39 } 40 pTextStyleTable->close(); 41 pTextStyleRecord->close(); 42 43 44 return true; 45 }
4增加blockref到model
1 bool AddblockrefToModel() 2 { 3 if(pMS == NULL) 4 return false; 5 AcDbBlockTable *pBlockTable ; 6 AcDbObjectId pTitileBlockId; 7 // Open the block table for read 8 Acad::ErrorStatus es ; 9 if ( (es =acdbHostApplicationServices ()->workingDatabase ()->getBlockTable (pBlockTable, AcDb::kForRead)) != Acad::eOk ) 10 return false ; 11 12 if ( pBlockTable->getAt("xxx",pTitileBlockId) == Adesk::kTrue ) 13 { 14 return false ; 15 } 16 pBlockTable->close (); 17 18 19 AcDbBlockReference * pTitileBlockRef = new AcDbBlockReference(AcGePoint3d(xx ,yy,zz),pTitileBlockId); 20 AcGeScale3d pscale(scale); 21 pTitileBlockRef->setScaleFactors(pscale); 22 //设置属性 23 24 pMS->appendAcDbEntity(pTitileBlockRef); 25 pTitileBlockRef->close(); 26 27 return true; 28 }
5遍历block中的属性 //与遍历block中的实体相似
1 AcDbObjectIterator *pBlkRefAttItr=pBlkRef->attributeIterator(); 2 for (pBlkRefAttItr->start(); !pBlkRefAttItr->done();pBlkRefAttItr->step()) 3 { 4 AcDbObjectId attObjId; 5 attObjId = pBlkRefAttItr->objectId(); 6 7 AcDbAttribute *pAtt = NULL; 8 Acad::ErrorStatus es = acdbOpenObject(pAtt, attObjId, AcDb::kForRead); 9 if (es != Acad::eOk) 10 { 11 acutPrintf("\nFailed to open attribute"); 12 delete pBlkRefAttItr; 13 continue; 14 } 15 if (strcmp(pAtt->tag(),"TITLE:") == 0) 16 { 17 CString title = pAtt->textString(); 18 if (strcmp(title,"PROGRESS(D)") == 0) 19 { //操作 20 } 21 else if (strcmp(title,"PROGRESS(P)") == 0) 22 { 23 //操作 24 } 25 } 26 pAtt->close(); 27 }
6公差标注设置函数：
1 void SetDimtpAndDimtm(double tp,double tm) 2 { 3 AcDbDimStyleTable *pDimStyleTbl; 4 acdbCurDwg()->getDimStyleTable(pDimStyleTbl,AcDb::kForRead); 5 AcDbDimStyleTableRecord *pDimStyleTblRcd; 6 pDimStyleTbl->getAt("",pDimStyleTblRcd,AcDb::kForWrite); 7 if (fabs(tp) == fabs(tm)) 8 { 9 pDimStyleTblRcd->setDimtfac(1.0) 10 } 11 else pDimStyleTblRcd->setDimtfac(0.5); 12 if (tp == 0.0 && tm == 0.0) 13 { 14 pDimStyleTblRcd->setDimtol(0); 15 } 16 else 17 { 18 pDimStyleTblRcd->setDimtp(tp); 19 pDimStyleTblRcd->setDimtol(1); 20 pDimStyleTblRcd->setDimtm(tm); 21 } 22 pDimStyleTblRcd->close(); 23 pDimStyleTbl->close(); 24 }
