动态拖放时的绘制事件：

1 2 3 4 5 6 7 8 9 10 11	`function` `DynWorldDrawMatrix1( pCustomEntity, pWorldDraw, curPt) {` `//与用户交互在图面上提取一个点` `var` `vBasePt = pCustomEntity.GetPoint(``"BasePoint"``);` `//绘制一个直线` `//参数一直线的开始点x坐标，参数二直线的开始点y坐标，参数三直线的结束点x坐标，参数四直线的结束点y坐标` `pWorldDraw.DrawLine (vBasePt.x, vBasePt.y, vBasePt.x, curPt.y);` `pWorldDraw.DrawLine (vBasePt.x, curPt.y, curPt.x, curPt.y);` `pWorldDraw.DrawLine (curPt.x, curPt.y, curPt.x, vBasePt.y);` `pWorldDraw.DrawLine (curPt.x, vBasePt.y, vBasePt.x, vBasePt.y);` `}`
