AcDbText::position Function
AcGePoint3d position() const;

        This function returns the insertion point of the text in WCS coordinates.
        If vertical mode is AcDb::kTextBase and horizontal mode is either AcDb::kTextLeft, AcDb::kTextAlign, or AcDb::kTextFit, then the position point is the insertion point for the text object and, for AcDb::kTextLeft, the alignment point (DXF group code 11) is automatically calculated based on the other parameters in the text object.
        For all other vertical and horizontal mode combinations, the alignment point is used as the insertion point of the text and the position point is automatically calculated based on the other parameters in the text object.
        The position value is the WCS equivalent of DXF group code 10.
大概意思就是:verticalMode() == AcDb::kTextBase时,如果 horizontalMode()== AcDb::kTextLeft 或 horizontalMode()== AcDb::kTextAlign 或 horizontalMode()== AcDb::kTextFit,那么position() 函数就是文字的插入点,否则alignmentPoint ()就是插入点

AcDbText::alignmentPoint Function
AcGePoint3d alignmentPoint() const;

        This function returns the alignment point of the text.
        If vertical mode is AcDb::kTextBase and horizontal mode is either AcDb::kTextLeft, AcDb::kTextAlign, or AcDb::kTextFit, then the position point (DXF group code 10) is the insertion point for the text object and, for AcDb::kTextLeft, the alignment point is automatically calculated based on the other parameters in the text object.
        For all other vertical and horizontal mode combinations, the alignment point is used as the insertion point of the text and the position point is automatically calculated based on the other parameters in the text object.
        The alignment point value is the WCS equivalent of DXF group code 11.

获取文字插入点函数如下
        AcDbText * pEntityPtr;
        AcGePoint3d insertPosition;
        if (pEntityPtr->verticalMode() == AcDb::kTextBase)
        {
                TextHorzMode hzModel = pEntityPtr->horizontalMode();
                if (hzModel == AcDb::kTextLeft ||hzModel == AcDb::kTextAlign || hzModel == AcDb::kTextFit)
                {
                        insertPosition = pEntityPtr->position();
                }else{
                        insertPosition = pEntityPtr->alignmentPoint();
                }
        }else{
                        insertPosition = pEntityPtr->alignmentPoint();
        }
