DIY - Large Address Aware SketchUp (Make SU use the 3GB switch)

[thomthom]

NOTE: Read all the information and warning before you attempt any of this.

I came across this article at Microsoft: http://www.microsoft.com/whdc/system...AE/PAEmem.mspx

Application Changes. No APIs are required to support application memory tuning. However, it would be ineffective to automatically provide every application with a 3-GB address space.

Executables that can use the 3-GB address space are required to have the bit IMAGE_FILE_LARGE_ADDRESS_AWARE set in their image header. If you are the developer of the executable, you can specify a linker flag (/LARGEADDRESSAWARE).

To set this bit, you must use Microsoft Visual Studio Version 6.0 or later and the Editbin.exe utility, which has the ability to modify the image header (/LARGEADDRESSAWARE) flag. For more information on setting this flag, see the Microsoft Visual Studio documentation.

Some manufacturers preconfigure their applications to use application memory tuning, making it unnecessary for you to make this change. For more information, see your application documentation and contact your application vendor to determine whether they support Large Address Awareness or whether you can enable it in their application.

This means it's possible for us to make SketchUp make use of the 3GB switch.

Here's an How-To that describes how to make Poser make use of the 3GB switch, same procedure applies to SU. http://www.keindesign.de/stefan/poser/3gb.html

Be very careful when you do this...make sure you've backed up your files and be prepared to reinstall windows if things get out of hand. Thats worse case scenario and there most likely won't be any issues, but you can never be too certain in the world of computers.
