(0.8mm等于&32分之一英寸). 导致很多小的短线无法绘制.在轻钢薄壁构件里,其厚度有的只有0.5, 有的是0.7, 均无法绘制. 这给Revit的工作带来一些局限性.这里有一个用编程的办法来绕弯路创建小于0.8mm, 其用法确实有点难以想到.首先我们创建一个长度放大100倍的长线. 然后给这个线添加尺寸约束,并绑定到一个参数上. 最后指定参数的值为实际长度. 最后删除标准和临时参数. 这样就可以绘制出来长度小于0.8mm的线.下面是代码演示. 大家可以自己看下.[Autodesk.Revit.Attributes.Transaction(Autodesk.Revit.Attributes.TransactionMode.Manual)]
