Pattern editing results in Unidentified bodies

[Anonymous]

I have patterned a body so that It can be used as a buttoned keypad. I wish to change the dimensions of the parent button body but when I'm rolling back the history marker, there are some entities from the patterned bodies that are misbehaving. I have tried rolling the history marker all the way to the beginning of the timeline but the said bodies are still shown in the file and there are multiple unidentified bodies in the browser. Unable to solve this issue. Please suggest. I'm attaching the files as well.

Hi @Anonymous, 

The first thing I would try is within the rectangular feature- change the pattern type from features to bodies, and then select that one body that you are trying to pattern. This will help the pattern become a more simple feature within your design. If you also need to pattern the hole, I would pattern it directly in the sketch and then cut them before you are patterning the body. 

I do see that there's something strange going on when you roll the timeline back, but let me know if this helps at all. It could be due to the workflow of the design. 

Thanks,

@julia.paganucci Thanks.

@Anonymous I took a look at the file and there are some bodies that do not belong. The file is attached to a bug report to hopefully help keep this happening in the future. I will ask if there is a way to clean the file but I can't guarantee anything can be done.

Sorry for the inconvenience.

@julia.paganucci  Thanks for the reply.

I'm trying your suggestion but I haven't noticed any performance or behaviour improvement but I'm going to keep this in mind for future. Any suggestion on how to solve the unusual behaviour of the additional bodies that get created when I roll back the timeline? I'm really struggling because of that.

Also when I followed your suggestion, I still had some unidentified bodies from the previous pattern operation.

They just don't seem to get resolved.

Thanks a lot Phil.

I'm facing this issue with all other designs where I have patterned bodies. Whenever I roll back the history marker, I still see the bodies in the browser and sometimes in the 3D model as well. Really hoping to find a solution or I'll have to model each design change in a new file.

If there is anything I can do to help, please let me know.

P.S.: I have tried clean uninstall and reinstalling fusion 360 as well as exported the said design as .f3d on the hard drive, uploaded back to fusion360 and trying to work on the newly uploaded file, but this file also as the unidentified bodies.

Unfortunately the issue lies in the data, not your installation. That's why I need help from a developer to know if the file can be cleaned. I'll post that to you as soon as I know one way or the other. I cannot promise anything now.

What would really help is to know your workflow that produces this result. It's one thing to have your file (thanks!) but that doesn't really tell us how you the issue is happening. If I can get your workflow steps and they can be repeated to create a simple file with this result, the developer can analyze "where" the steps need to be corrected in the code, which is called debugging. You are doing nothing wrong, but I need to know what you are doing. The idea is to allow your workflow without producing this bad result. 

If you can try again your workflow, using simple shapes, and get this result, please let me know what those steps are. You can post them in an IM to me or I can connect with you via email. A simple numbered list will work. I'm sorry for the inconvenience, but this is the fastest way to get this fixed, and you'll be helping not only yourself but other users that may use your workflow. 

Thanks,

I have this problem as well, exactly. I suppose there's no way to fix it. The ones I put in the bug bodies folder. These don't correlate to anything in my timeline. I can move the timeline all the way to the start and they remain. I cannot delete them.

The best I can remember, they appeared after I did a circular pattern of a feature (specifically a feature, not bodies or components). I've since removed this feature because it didn't give me a desired result, but then these unidentified bodies appeared.

@Anonymous As I posted above, I believe this can be fixed if we can figure out how to repeat it. Do you recall the steps you took? 

Another way to tell what happened is to see a version of the file prior and after the phantom bodies showed up.

Thanks,

It first appears in v22, it's not in v21. Between the 2 versions I did a few hours of work recreating the sketches and bodies to a larger scale, but again as I said earlier, the stage in which I remember these unidentified bodies appearing was after I did a circular pattern of a feature that consisted of extrusion and chamfers.

When deleting one of these bodies I get an error... See the screenshot.

[Phil.E]

Yes that is expected. 

Can you possibly export and send me, or post, those two versions? That would probably help us solve this once and for all. If you can't do that, can you invite me to the project so I can gather the two versions privately? phil dot eichmiller at autodesk dot com.

v21 doesn't have the problem, v22 does. They're attached.

It is difficult to reproduce. I've been going through a few ideas, but the original model was pretty complex so it's hard to nail down the issue that caused it. Is there not some way the data can be manipulated and these bodies can get removed?

[Phil.E]

Thanks for the models. 

At this time I don't know of a way to remove the bodies. I have asked if that's possible. One possibility is promoting v21 and redoing the work of v22. This might cause the problem again, which would be good I suppose, if you captured the exact steps, but then I don't want you to waste your time. Hopefully we can figure it out. Let us know if you spot any key info that will help here. 

Thanks again,

That would be starting over since between those 2 versions I actually completely remade the sketches so that the model was double the size. I'm tempted to do just that, with a new model, and save more often just in case this happens again.
