McDbAlignedDimension 类

McDbAlignedDimension类用于表示标注空间中任意两点距离的标注类型。标注的法向矢量必须与两点之间的线垂直。两个选择的点也作为两个标注界线的开始的定义点

C++

class McDbAlignedDimension : public McDbDimension;

备注

例如: 控件中绘对齐标注的代码

    void CDrawCommand::DrawAlignedDimension()
    {

        mds_point pt1;
        if(Mx::mcedGetPoint(NULL,_T("n 指定第一条尺寸界线原点:"),pt1) != RTNORM)
        {
            return;
        }

        mds_point pt2;
        if(Mx::mcedGetPoint(pt1,_T("n 指定第二条尺寸界线原点:"),pt2) != RTNORM)
        {
            return;
        }

        Mx::mcutPrintf(_T("指定尺寸线位置:"));

        McGePoint3d xLine1Point = asPnt3d(pt1);
        McGePoint3d xLine2Point = asPnt3d(pt2);
        McGePoint3d dimLinePoint = xLine2Point;

        McDbAlignedDimension* pDim = new McDbAlignedDimension(
            xLine1Point,
            xLine2Point,
            dimLinePoint,
            NULL,
            Mx::mcdbHostApplicationServices()->workingDatabase()->dimstyle() );


        // qjx test
        //pDim->setOblique(MxBase::kPI / 3.0);


        CDrawAlignedDimensionJig jig(pDim);
        if(jig.DoIt() )
        {
            MrxDbgUtils::addToCurrentSpaceAndClose(pDim);
        }
        else
        {
            delete pDim;
        }
    }

例如: 倾斜的尺寸标注的代码

    void CDrawCommand::ObliqueDimension()
    {
        MrxDbgRbList spFilter = Mx::mcutBuildList(RTDXF0,_T("ROTATEDDIMENSION,ALIGNEDDIMENSION"),0);
        McDbObjectId objId1;        
        McGePoint3d  ptPick1;

        if(MrxDbgUtils::selectEnt(_T("选择需要倾斜的尺寸标注:"),spFilter.data(),objId1,ptPick1) != RTNORM)
        {
            return;
        }

        McDbObjectPointer<McDbDimension> spDim(objId1,McDb::kForRead);
        if(spDim.openStatus() != Mcad::eOk)
            return;


        double dAng = 0.0;
        if(McDbAlignedDimension::cast(spDim.object() ) != NULL)
        {
            McDbAlignedDimension* pAlignedDim = McDbAlignedDimension::cast(spDim.object() );
            dAng = pAlignedDim->oblique();
        }
        else if(McDbRotatedDimension::cast(spDim.object() ) != NULL)
        {
            McDbRotatedDimension* pRotatedDim = McDbRotatedDimension::cast(spDim.object() );
            dAng = pRotatedDim->oblique();
        }
        else
        {
            MXASSERT(0);
            return;
        }

        double dRetAng = dAng;
        if(!GetNewAngObliqueDimension(dAng,dRetAng) )
            return;


        if(!MxT::IsEqual(dRetAng,dAng,0.001))
        {
            if(!MxT::IsZero(dRetAng))
            {
                if(dRetAng < MxBase::kPI / 4.0
                    || dRetAng > MxBase::kPI * 3 / 4.0
                    )
                {
                    AfxMessageBox(_T("角度不合理.."));
                    return;
                }
            }

            spDim->upgradeOpen();

            if(McDbAlignedDimension::cast(spDim.object() ) != NULL)
            {
                McDbAlignedDimension* pAlignedDim = McDbAlignedDimension::cast(spDim.object() );
                pAlignedDim->setOblique(dRetAng);
            }
            else if(McDbRotatedDimension::cast(spDim.object() ) != NULL)
            {
                McDbRotatedDimension* pRotatedDim = McDbRotatedDimension::cast(spDim.object() );
                pRotatedDim->setOblique(dRetAng);
            }
        }

    }
