Derived Objects Export Status Turned Off During Rebuild All

[estringer]

When running the Rebuild All command on assemblies, the Export Status if some derived objects is being turned off. What could be causing this and is there a way to prevent it?

Hello!  A quick search of that error turned up the following Google AI Generated answer.  This has not been vetted against any Autodesk official documentation, but it might help you to narrow down the cause:

In Autodesk Inventor, the "one or more derived objects have had their Export status turned off in the source" message indicates that a derived part or assembly is referencing objects in the base component that are no longer set to be exported. This usually happens when the base component is modified, and objects previously marked for export are no longer marked, or when the base component is opened in a version of Inventor that has a different default export setting for certain objects. 

It goes on to suggest that the Design Doctor will help you to identify which part is causing the issue, so you can attempt to fix it.

@CGBenner ,

Thank you for your response! I have become quite adept at finding and fixing the problem Export Status. I know that no one is changing the export settings or turning off the export status so I am convinced that the Rebuild All is what is causing the issue because I see it happen immediately after I run it.

@estringer 🤔

I wonder if the Rebuild All could be reaching down to those components and changing the Export status?  @johnsonshiue is this possible?

It happens to me on occasion - usually hundreds of parts need to be opened and have their derived link edited and closed to fix.

To shortcut this tedious & time consuming annoyance I have found that if you deliberately make further changes such as adding additional geometry or altering dimensions to the master part sketch that is no-longer marked for export, then when you rebuild the parent assembly it will often be cleared.

Hi Ed,

I am not aware that Rebuild All can cause an exported object to become not exported. If there is a repeatable workflow,  it will be a bug. Please let me know asap.

I guess one possibility is that the export status was not saved back to the derived source file. Although it appears working, the link may have been broken because of lack of the export status. Rebuild All simply reflects the fact.

Please let me know if you have reproducible steps.

Many thanks!

Hi Johnson,

It is not reliably reproducible - you can press rebuild all many time in a row and nothing will happen.  I suspect it is some occasional issue related to the read/write availability status of the master part causing derive status flipping- possibly due to using cloud backup software on the inventor project folder (dropbox in my case).

Fortunately if you make large enough changes high enough in the master part model tree then that can 'reset' the derive status in the child parts.

Interestingly this can also solve problems with child parts not updating derived geometry including 'hung' block definitions and the dreaded stuck rebuild 'lightning' symbol on the block definition that can crash inventor if you try and update the child parts directly.

[estringer]

We aren't using any cloud based backup software and it is also not reliably reproducible for us. I just know that it happens enough to cause frustration.

I wonder if it occurs for you when you have pressed rebuild all on a large assembly & windows is still saving files to disk & then you press it again before it finishes?  Also if you have the master part open in inventor or have thumbnails being regenerated in windows explorer?  It just has the feel of some kind of access limitiation on the file itself causing the frustrating randomness of the problem and thus the inablility to reliably reproduce.

[estringer]

It happens immediately after I press rebuild all one time.

@estringer 

Hi, were you able to get this resolved or do you still need some help?  If it can be repeated within one specific assembly maybe share that Pack and Go so @johnsonshiue can examine it?

[estringer]

@CGBenner,

I was unable to get it resolved. The problem is that it does not occur consistently so I have no way of tracking what may have caused it or the steps it took to get there. As far as I can tell, I just push Rebuild All and it happens.

@estringer 

That can be so frustrating.  We all know something is going on, but until we can reliably reproduce it it's near impossible to nail it down.  We can keep an eye on this thread and if anyone is able to find a project where it can be predictably reproduced then we may have something.  I had this happen to me a lot of times when I was on your side of the wall.  😞
