Inventor is freaking out

IV 2017 Windows 7 64 bit

I have several issues all at once. They may or may not be related.

These were occurring before I installed Inventor2017_R2.exe. I think they have been getting worse.

I've attached a screenshot of a sketch with constraints visible. There are two yellow lines. The right line is the projected line (hence the red constraint icon), and the left is the source. The screenshot is shown normal to the sketch plane. It is for a cut extrusion in an assembly. It's been working for months. There's another assembly that has, essentially, the same drawing cutting the same features in other assemblies. It still works just fine.

Backing out of the sketch, the extrusion feature in the feature tree shows up healthy, but the extrusion doesn't happen in the assembly. Other features and parts need this extrusion to work, and they error out.

If I edit the extrusion in question, the closed profile seen in the screen shot highlights as seen. I don't change anything, and hit "OK," and the extrusion cuts away everything it's supposed to, not just the broken sketch. If I edit the sketch again, the projected line works fine.

A part is supposed to mate to one of the cut faces. The mates all appear healthy in the tree, but aren't working correctly. A coincident mate that's supposed to be zero inches apart is over 17 inches. If I change the mate to be 5 inches (just something arbitrary), the part sometimes pops to 5inches away, sometimes 12ish.

This can keep going, chasing down parts that aren't behaving as they should. Everything in the assembly was fully constrained, as simply as possible. It had been working just fine with no issue.

I have closed and reopened the assembly, Inventor, and rebooted the computer. This is still happening.

My CPU usage and Memory usage has gone up. Usually, my 8 core CPU usage is below 10% at rest, and my memory usage is 4-5gigs.

Now, my memory usage is upwards of 8GB at rest. I've been closing everything extra I can handle, but it's not making a difference.

Now, either 4 cores are running around 25%, or all 8 cores skyrocket up to 90-100%

I'm having multiple instances of node.exe running on my computer. Anyone have this issue before??

My apologies for not being able to write something more concise, but I'm out of time for the day, and am hoping someone has experience or insight with this...

Hi eveylynne,

Can you post the related files? I don't think anyone will be able to guess what the issue is without looking at the actual files.

I hope this helps.
Best of luck to you in all of your Inventor pursuits,
Curtis

Alas, everything is proprietary. 😕

Oh, this is happening, too, when I do half section views...

Hello @Anonymous,

It will be difficult to tell whats going on without the files and understand you cannot attach them. If you feel this issue has been caused by R2 you can uninstall it and retest it but this maybe file related.

Best Regards,

Don
