Hello All,
I have an issue that Inventor 2014 refuses to fully updated drawing views and make them precise if the drawing is of a large assembly. Usually this occurs when going back and updated a drawing already created and the assembly has recently been updated. I'll have high RAM usage at the time (4-7Gbs) but my system has 40 Gbs of DDR4, 2400 Ram installed. I have set the undo file size to be 4095 MB as that is the maximum for Inventor 2014. If I save the assembly and close out of inventor completely to free up the RAM and then reopen the drawing it updates and makes all the views precise very quickly. Is there a way to eliminate the need to constantly exit out of Inventor before updating drawings of large assemblies?
System Details:
Inventor 2014, 64 Bit
Intel Xeon E5-1630 v4 CPU @ 3.70 Ghz
40 Gbs of DDR4 Ram, (2x 4 Gb DIMM, and 1x 32 Gb DIMM)
Nvidia Quadro M5000
NVMe SSD 950, 500 Gb (272 Gb Free)
Hi! The behavior does not sound right to me. Without seeing the actual Inventor files, it is hard to tell where the exact problem is. A few things to try, though I don't have access to Inventor 2014 at the moment to double-check.
1) Make sure all critical Windows updates are installed and graphics driver is up-to-date.
2) Start up Inventor. Go to Tools -> Application Options -> Assembly tab -> uncheck "Enable Express Mode." Open the assembly referenced by the drawing views and save. The iam file should be very small. Try the update workflow.
3) Go to Tools -> Application Options -> Drawing tab -> uncheck "Enable Background Update." Try the update workflow.
4) Download Inventor Pro 2019 and try the exact same workflow.
On Inventor 2016 and earlier, the ability to handle large assembly and its drawing is not optimized. It can certainly build large assemblies with 100K components but you may run into poor performance from time to time. You may want to try Inventor 2018 or 2019 to see it the same issue exists.
Many thanks!
This seems to have helped in the sense of updating drawing views after changing something in the assembly. I still don't think it wants to utilize above a certain amount of RAM which I can't imagine why. regardless I'm getting better performance.
Hi! I suggest you consider upgrading to 2018 or 2019, since there is a lot of improvement targeting large assembly modeling and drawing performance. It should be a lot faster than 2014.
Many thanks!
