Revit 2018 - Crop Regions not cropping linked files properly...

[jmqrsq]

We are having an issue with our viewports showing a much bigger area than they should. It appears that the crop region is not cropping the linked file properly. Is there a fix for this? Has anyone else come across this in 2018? I have never seen this before. Is there a new setting I am missing per view instance? Some views are fine and normal. Some on the same sheet are not. I am pretty sure it is related to the linked file background...

Thanks

I can tell you that this project is using C4R if that matters

Think I figured it out: I had to go into our view template and set the link to CUSTOM and then click the annotation tab and use the pulldown and select custom. Then I unchecked the SHOW ANNOTATION CATEGORIES IN THIS VIEW option and it worked. I beleive if you just uncheck the GRIDS category that would work as well. My guess is that the viewport is trying to clip out at the links grids. This has fixed the issue 100% of the time I have tried today. FYI106079106079
