Unknown Performance Issues with Inventor

[548swimmer]

I agree your hardware should be more than enough to run Inventor, but is it possible you're overdrawing still? What color is the RAM bar in the bottom right hand corner? The less full it is the better.

In order to figure out if this is a hardware or software issue, I'd check your performance monitor equivalent. If the CPU load is low, and the RAM is under 50% usage, the problem is with Inventor.

Hope this helps.

The highest I've ever seen my memory usage spike is about 2.5GB. Which seeing as I have 6GB should still be more than enough.

I'll have to get back to you about my CPU usage though.

The most common problem I see in a situation like this is a conflicting assembly constraint. Impossible to diagnose without sitting in front of the machine - but I would make a substantial wager that is the problem. You might be able to isolate it by removing parts or subs one-by-one. When I sit down to find a problem like this I can usually find the suspect part or assembly fairly quickly.

I would rate almost everything I see done in Inventor as garbage. Garbage in - garbage out. There is a real problem with professional level training.

If you can pack and go the assembly and send it to me I'll take a look. (be sure to preserve file/folder structure) jmather_at_pct_dot_edu

There are several constraints I've seen with errors on them. And as you said, they don't seem to be uncommon. I never realized that conflicting constraints could cause such severe performance issues.

I can take a look at them myself over the weekend since I finally have some time and I'll report back my findings. I'm used to having to deal with broken and conflicting constraints with the Unigraphics models I work with at my job.

Thank you for that insight though. I really had no idea that conflicting constraints could do anything to the performance of Inventor except just make it error prone in terms of getting proper movement and proper association.
