批量计算封闭对象的总面积，并标注于图中指定位置-Batch computing the total area of closed objects, and mark the location specified in Figure

在进行桥梁后张法预应力施工时，需对钢绞线理论伸长量进行计算，以便在施工中与实际伸长量对比，复核混凝土中钢绞线是否正常拉伸。本工具可在CAD中画好钢绞线形状，选取后输入张拉参数，可在excel中生成结果报表。方便施工计算，特别是有不规则梁体时。-After conducting tensioned prestressed bridge construction, the need for theoretical strand elongation is calculated to compare
