Problem with flexible movement in Inventor 2023

lanUKNAP — Fri, 01 Apr 2022 11:25:56 GMT

I hope someone can help me. I have just updated to Inventor 2023 from 2022 and I am having problems with the movement of part in my existing assemblies.

As soon as a part gets a constrain I can not move it freely in the remaining dimensions any more. If I remove the constrain again I can move the part freely in 3 dimensions.

Also all my flexible subassemblies does not work any more. They will not move.

However if I make a completely new assembly flexible subassemblies work fine and I can move part freely with one or more constrains.

What can I do so that do not have do all my assemblies all over again?

I have tried migrating the assembly and the flexible subassemblies.

I have have tried "Rebuild all".

Update: A nonsolution is if I delete all patterns in the assembly. This also affects if I make a new assembly. So I guess there is a bug where patterns and free movements and patterns cannot coexist in the same assembly.

Encountered the same issue today, on making first constraint the part was locked and can not be freely moved in other directions.

Then seemed ok again in another assembly, but hadn't realised the issue was with a previous version assembly?

Ill run some tests to clarify when issue is present.

Confirming the bug is as you state, once a assembly has a component pattern, additional parts loose free movement with the first constrain.

Additional constrains still work but you can not drag parts to position prior to adding them.

Some more comments from users please

I have sent a bug report to Autodesk. With the video in the link below.

It is still quite early in California so we will see if they will answer later.

Confirmed when a pattern is present

Hi Folks,

The behavior looks wrong to me. I tried a very simple case but I could not reproduce it. If possible, please share an example that exhibits the behavior. I would like to understand it better. It should just work.

Many thanks!

I have made a small example.

It contains a pattern and a flexible subassembly and a part with a single contrain.

If i remove the pattern the flexible subassembly works and I can move the part. If I keep the pattern and just remove flexibilty I am also able to move the part but I cannot make them coexist.

However in my real assembly removing flexebility does not help in being able to move my part. Only removing the patterns helps. But I can not share that with you here.

Similar to LanUKNAP

See attached simple assembly & Parts, adding a part (bar) then creating a pattern (x4) is all good. Adding additional parts (5th Bar example) and it locks position when applying the first constraint and can no longer be dragged in the free directions.

Just noticed one of the parts need to either be constrained to origin or grounded for the issue to be present.

Hi! Yes, it is a confirmed defect on 2023.0 (INVGEN-60561). Basically, when the pattern source components have a constraint, the entire component pattern will lock up. This is absolutely wrong. We are actively investigating the issue. Hopefully, we can fix it asap. In the meantime, please use Free Move to relocate the components.

Many thanks!

Good morning Johnson,

perhaps not really the same background, but a similar issue. If the attached fileset is opened with 2022, the wheel can be turned. If opened in 2023, no turning is possible.

Hi Walter,

Many thanks for sharing the files! Yes, this is the same issue. The problem is with component pattern. Whenever there is one, the DOF will be unreasonably restricted. This is the bug. We are working on a fix. We will release 2023.0.1 to address the issue soon. I am very sorry from the trouble.

Thanks again!

Thanks Johnson.

I've informed the user in the German Inventor forum about the cause.

Hi Johnson,

Can you please indicate when this issue will be resolved.

Thanks

Hi! The update is scheduled to be live some time next week. I cannot commit a specific date.

Many thanks!

We're currently Beta testing the 2023.0.1 update build prior to final release. If you would like to try that then you can apply for access using http://Autode.sk/InventorBeta

Thanks

I don't know why this problem has been marked as solved as the issue still persists. What was the solution?

Re: Problem with flexible movement in Inventor 2023

lanUKNAP — Fri, 06 May 2022 10:54:58 GMT

well, I expected it was a bug so when it was said that there was a fix underway I marked it as solved. However I thought that it was going to be released quicker since it was a well described and easily reproduced problem, but appearently it is still in beta.

Re: Problem with flexible movement in Inventor 2023

lancermandc_co_za — Fri, 06 May 2022 11:09:34 GMT

This problem is not just linked to objects constrained on a circular pattern as some people have mentioned, but also singular object that have just one constraint.

I agree with you on the length of time Autodesk are taking to fix this, rather frustrating....

It was that annoying I joined the beta programme...My team now have full constraint freedom again...
