ObjectARX标注公差简单实例

代码

		ads_name ent;
		ads_point pt;
		if (RTNORM != acedEntSel(_T("\n选择对象: "),ent,pt))
		{
			return;
		}
		AcDbObjectId objId;
		acdbGetObjectId(objId,ent);
		AcDbObjectPointer<AcDbDimension>pDim(objId,AcDb::kForWrite);
		Acad::ErrorStatus es=pDim.openStatus();
		if (Acad::eOk != es)
		{
			return;
		}
		//开启公差
		pDim->setDimtol(true);
		//DIMLIM 
		//pDim->setDimlim(true);		
		//居中对齐
		pDim->setDimtolj(1);
		//公差下标
		pDim->setDimtm(0.01);
		//公差上标
		pDim->setDimtp(0.02);
		//公差高度比例
		pDim->setDimtfac(0.7);

效果
