will deleting old files improve performance?

conjured2018 — Wed, 15 Dec 2021 14:13:12 GMT

I am hurting bad with slow speed. wondering if deleting old files will help?

Please tell me if I can send file via private email for review. I can not post to forum.

If the files are in the Cloud, Autodesk is carrying the performance load. If you are saving locally, perhaps but not likely.

@conjured2018 - slow speed doing what kind of thing? If the slowness is in, say the data panel, or in the Open dialog, then, maybe deleting old designs can help. But, if you are dealing with graphics performance, or modeling performance, or sketch performance, then no, that has nothing to do with the number of projects/designs in your hub.

Jeff, I have done all this many times without problems. I am trying to move parts both x y and trying to rotate. the flat move works slow but ok, the rotate just locks me up. In addition, I have used align many times in past to get parts on a single plane for machining. Now just opening align locks up and does not allow selection.

when i say locks up, Iam talking about excess of 10 minutes to do op. I am using a derived file with 5 sketchs and just a few bodies. I have done clean uninstall and re install. My computer is set to performance and is i5 quad with 32 gigs of mem. graphics card is new and is 4gig mem and open gl.

while typing this I am trying to open a file, this is taking over 20 minutes. Please see screen shot.

A couple of comments:

an i5 is a bit underpowered for Fusion. I'm not sure whether that is the source of the problem, or if there is something else. Would have to see the design to be sure.
pure number of bodies or sketches does not necessarily relate to performance. Certainly, lots of bodies or sketches can lead to bad performance, but a few sketches or bodies can still result in bad performance, if those bodies or sketches, themselves, are complex. Especially sketches - it is easy to end up with a complex sketch that, by itself, can kill performance.
interesting to see your comments on move - just to be clear, you are using Move, with the type set to Components? And are seeing differences between translation and rotation. I have not seen any cases where this is the case. Would be interested in seeing that.
an open of 20 mins is certainly very slow. If you export this design to disk, how large is it in MB?

I sent a 5.6mb file to your email address

Yes move moves ok with same plane move but the rotation locks for several minutes. I set at bodies. altho all top level parts are components

Jeff what is best way to align several parts to x y plane?. One fellow told me I use align too much.

I just had no issues with same PC doing move, align etc. align is a complete lock

I am in other files now on same PC and all is OK. JR

OK, that is good information. If you want to share the problem design with me privately, see my response to your DM. I would like to see what is in that design that might be causing issues. Thanks.

thanks for sharing the design with me, @conjured2018 - I can definitely verify that something weird is going on with this design. I think it is geometry-related. I can verify that translate is smooth, while initial rotate is slow (though subsequent rotate seems OK - it's just that first one).

One observation - there are no components in this design, only a set of bodies. That is not a problem, but it does mean that the problem is in body Move, not Component move (which is a much different operation internally), so having the design is valuable for us to debug it.

Open is slow for me, but definitely under 20 mins. That could be the i5 vs i7 processor speed, however.

The bodies in this design are certainly a bit messy (small sliver faces, lots of what appear to be "extra" faces, etc). Where did the geometry for these bodies initially come from? The design is a Direct Modeling design, which makes me think that this data is imported. If so, do you have the original design available?

Finally, until we figure out what is slow in this design, I did find that export to STEP and re-import helps a lot. As a short term workaround, you might try that. I will email you the STEP design.

Jeff, thank you and merry Christmas.

Please see attached file for look at my process.

1. i free form sketch, dont know how to constrain so I dont.

2.I extrude on base design say the bucket and then use extrude and spline or arc to trim. I use many planes, both types. I there are only 5 base parts which I duplicate, then use align to join.

3 to cut curves i use sweep both to cut and to add. I use alot of extrude to cut if fits part. I want parts smooth no artifacts,

4. I use loft to build some parts.

5.cam process is to split body into 1.5 inch parts and lay out on 4ft by 4ft plane. I use align to get parts on plane, now align does not work.

thanks JR
