Reducing the file size

Revit

1

Hi there,

I am building a model for roads currently. Attached are the Dynamo that I had been used. However, it had already generated 800MB for my Revit model, given that I still had two more roads to go. This file size had already made my Revit slower. Any suggestions for reducing the file size or any ideas why the file size surged to this big?

Thanks

What’s the Size of your CAD Link?

They are in total 400kb
Does it matter? Or any simplification can be done to the dynamo code?
