在Revit2018以后，修改了Grid的Reference获取办法，需要使用下面的代码进行获取

foreach (Grid grid in grids)
           {
               var reference = new Reference(grid);
               gridReferences.Append(reference);
           }

而在之前是需要获取Grid的Curve.Reference才能进行标注创建

1	gridReferences.Append(grid.Curve.Reference);

改动应该是为了更加安全便捷的获取Grid的Refence而做出的修改。关于这个事情的官方回答详情可以看下面这篇文章

Breaking an Arc into Multiple Segments

The company plugin’s beam-to-slab function has been updated. The designer requested a feature to split arc beams and align them to the top of the slab.

Revit API Ray Method Returns Two Values for Same Element Analysis

Ray intersection is one of the most commonly used nodes for collision calculation and distance measurement in many 3D models. However, when using the ray method and setting target to element, you will find that two identical values appear.Using floor distance as an example, two different values appear in the figure below. After I modified the slab thickness, I found that it was exactly the distance of the slab thickness. It can be guessed that the ray method determines intersection for both f...
