Curtain walls kill Revit.

[ar00302]

I am working on a school project. The Revit file size was around 250 Mb. The final step was to place some curtail walls. Not some a lot of curtain walls. Suddenly the file went over 2GB. Revit 2020 wasn't able anymore to save or open the file. Fortunately, I have also Revit 2021 which is able to open the file. But then after placing more curtain walls the file surpassed 5 GB. I used curtain walls to simulate build louvers.

My Computer is able to handle it but I understand that this is not good. Also, I receive messages that my file is corrupted and needs repair. I run purge and audit but the warnings remain.

Is this a generic Revit curtain wall problem or is it a specific file project?

Why not use louvers?

Are you using mullions to create your louvres?  If so, you may have thousands of these elements, in which case you can expect a substantial increase in your model size.

Perhaps create a louvre curtain panel and use that, as suggested by RobDraw.

what are your Curtain wall settings?

i use this method all the time for making rooftop and vent louvers all the time. i have seen in my office people forgetting to edit the Vertical Mullion Spacing.  When i check there model it is set to 2' or something like that. this will end up killing your model because it is placing a bunch of 2' long blades to make a 30' louver wall.  i will usually set my vertical mullion setting to None, then go back and manually place any verticals i need, if at all. 

one blade vs 20 blades in a 40' wall makes a big difference. (390 vs 3500 elements)

Instead of model the blades as curtain mullions or as arrayed families, simply use a material with a model pattern.
