Hello guys,

I am working in a building of 20.000 sqm with 12000 windows. when I am inserting them in the facade, the program ( Revit Building 8.1) goes so slow!!! and sometimes my computer says to me that I am running out of memory. But I have a 1Gb RAM!!!

It is normal that Revit, for some operations, goes so slow? maybe I am doing something wrong?

Yes, revit consumes a lot of PC resources.

I have 2G Ram and i'm thinking buy another 2G.

The processor and grafic card is also important.

Below are the Autodesk recommended specs to effectively run Revit.

 

System Recommendations:
  • Intel Core® 2 Duo 2.40 GHz, or equivalent AMD Athlon processor
  • Windows XP Professional (SP2 or later)
  • 4 GB RAM
  • 5 GB free disk space
  • Dedicated video card with hardware support for OpenGL® spec 1.3 or later
  • Two-button mouse with scroll wheel

The preceding requirements are recommended for effective use of Revit Architecture software.

Revit can get horribly slow and I've been trying to pin down exactly what does this.

 

I have theories, but one thing you might want to think about is your windows. When you have that many windows, Revit will be generating views with the detailed geometry, and maybe trying to generate all of them. 

 

What I would consider proposing would be to make 2 families of the windows with the same exact name in 2 separate folders. One that has all your detailed geometry in the windows and one with a simple opening and maybe detail lines to show graphically that it's a window. Then when you get ready to print, load the detailed window into your family and overwrite the simple version.

 

This would free Revit up from at least generating views for the windows and you might be able to work a little easier/faster on your project. Large firms, this might not be so welcome of an idea.

 

Check over your loaded families to see if there are any that are large sizes. This may indicate a jpeg was left in the family maybe, or it's a little too detailed.

In addition to the hardware specs, it is how you model and structure things in Revit that are important.  On large projects worksets are a must.  You can selectively open worksets so you do not have to deal with the whole model at once.  In 2008, you have stronger file linking options which need to be explored.  How you create your families is important too.  You should be making them as simple as possible and add detail to medium and fine views via 2D linework in the family that displays when cut in section.
