Undo File Size %

[Anonymous]

The Inventor Undo File Size I believe defaults to something like 1024 MB.

We deal with very large files and most users get the error they need to increase this file size.

The main question I get back is "OK, but to what amount?"

So as to minimize the trial and error of the process, what is the percentage threshold in Inventor for this setting where it doesn't kick back the error? Is it like 10% of the file size? 15%?

I know it may be a major undertaking, but it would be really nice to somehow have Inventor automatically adjust this file size setting per file instead of prompting the user to blindly estimate what they need to set it to. Especially if the user doesn't always deal with large files day in, day out. I.E. no need to have it set to 3000 MB for a small file that is fine with the 1024 MB setting.

Question for you..   How much disk space is the user's temp folder consuming on the hard drive?

C:\Users\<user name>\Appdata\Local\Temp..

Granted I don't usually work in large file but I never remember having to increase my undo file size in Inventor.

@Mark.Lancaster  mine's only set at 279 MB, not sure what the others are defaulted at.

Are you seeing the same message?

Increase size until IV don't complain anymore.

4GB is not a big deal nowadays.

I don't remember if IV delete the file when it quit.

My Pagefile is 64GB.

@Mark.Lancaster, no, I very seldom work in the assemblies the users do, I just manage the Support Group these days and get little chance to actually work in the applications unfortunately.

I typically set it to 2048MB & increase as/when required. Note that certain import/reference operations are tracked by the undo stream so if you're importing very large datasets then you might need to set it to something like 4096MB.

Undo files should always be deleted when Inventor exits (cleanly) but it's always good practice to delete everything from %temp% on a weekly basis anyway.
