I can appreciate the reason for the 20 mile extent for model elements, but surely we can make an exception for 2D CAD links? When modelling civil structures, we use these links on our Arrangement drawings and to collaborate between the different civil infrastructure disciplines. More often than not, the project extents are larger than 20 miles (with various separate Revit projects for each structure) and we end up having to export and crop up these CAD files before linking them into Revit. The time spent on this exercise is substantial with dozens of links being updated weekly, during the design process. Please help us to make Revit more efficient in the civil-structure space.
