My models exploded

Anonymous
Not applicable

I have had so much troubles with Fusion 360 lately. 

 

Insert into current design is causing terrible problems.

 

When I update the inserted model everything explode on the model it was inserted into. The same thing if I delete it.

 

Then I just hide it, save the model to be inserted on a different name so that it can be inserted again, and it does not insert correctly. the parts do not stay on their places and some parts are missing.

 

It tries to compute heavily and long and always with unwanted results. What is going on

 

I am using Latest MacOS on 15" 2017 MacPro.

and I can not export the model on my local disk on the .f3z format, it fails. Exporting as STEP worked and it opens ok. 

 

Saving as STEP and loading back has saved me many times, but it is really inconvenient and causes other problems, like loosing the names of the bodies, and many features, and the history is generated on wrong place.

 

Is there a better way to get rid of the history using native Fusion 360 format. That really is the feature I have been missing long. I just can not understand how deleting a scetch, or previously inserted model can destroy my hole model, and this is normal and expected???

 

And now al these problems deleting the inserted models. or even trying to update them. I do not remember having this problem before, at least not so bad. 

 

How do I get rid of all the history and delete old unused sketches and inserted models without making a total mesh. Preferably a better way than converting first to STEP and then back.

I think that you would be better off figuring out the root causes of your issues.

I would (generally) never do this, but since you asked...

From my point of view the root cause is that Fusion 360 is not stabile, each update brings new problems and the get long time to get fixed.

 

But it probably is also that I use the Fusion 360 wrong. The Sketches are for me mostly single use, unless it is something right now working on, but next day I rarely search for the old sketches, but just great a new one. So I end up easily 100 sketches and really would like to delete the old unused ones. The only way I have found safely to do this is to store as STEP and then back.

 

The problems with the links between the inserted models is something new. It started some time at this spring. It is something to do with capturing the positions. the work around I found was to go to the inserted model and do a scetsh so that it captures the positions and save it, after the parts stayed on the places they should, but that does not work any more, and it also breaks the model where it is inserted to the updating or removing. it. This could be as some parts might have been created with sketches that where drawn on the inserted model, but I do not remember this being problem before. 

 

Very rarely I modified a just created sketch and that can be useful, the the model is updated according to the changes, but other than that I newer use the history related functions other than undo. They are just pain int the... causing so many problems.

 

What practical use could the history functional have, how could it be manageable to go to delete some step in middle of history??

 

The above proposed solution is not working, it just moves the history from bottom of the screen to the side bar, and over time causes terrible amount of scrolling as that can not even be collapsed. So that is even less managable than having it at the bottom and not using it.

 

But thanks, that was actually one of the problems I had with the STEP files, the history is by default disable on a model that was imported as a STEP, causing the problem of uncuttable history on the side bar. 

 

I really hope there would be a button that deletes all the history, without going trough storing as STEP and importing back. I also really hope there would be a way to completely disable the history functionality just keeping undo, with out the side effect the history on the side bar, or what ever that is.

Hi,

The history can be disabled in the browser as @TheCADWhisperer has shown.

You can also set this setting as default in the preferences.
But I think that the described problems will not be solved with this.
Therefore it would be useful if you create a screencast of your approach, which then serves as a basis for hints. Furthermore a shared example design would help.

Well, going trough STEP solved it for now agin, but that took couple of hours totally unnecessary work. 

 

The original I can not export as f3z it fails, so I do not know how I would share it. Anyway will not publicly share it could share with Autodesk.

 

If I disable the history, it starts collecting the garbage on the side bar, that is even worse than having history wasting screen at the bottom. The bigger problem with history though is, it always causes problems at the end, or then something else is broken on the Fusion 360. This is not the first model I had problems with.

This is what happens. This time it hanged completely the I tried to get more info about the error. I had to shut the computer from button as Fusion 360 prevented the shutdown though the process was killed?

Normally the linked model goes a way, but the main model breaks.

 

Here is what normally happens. First updating try linked model. The upper part of the main model reverts to some older version and some things are broken. The update does not give errors, but it is not updated to the latest. the battery is 90 degrees of and probably other minor things. the version on the main model of the linked file is V9 and currently it is V11. Then trying to remove the linked file, once again it takes long time. the main model is clearly broken. At then end undoing the previous and hiding the linked model to show how the main model is.

Key to everything I do.

A good portion of my career was direct modeling - I am very good at it, but I would not want to go back, especially when I have to work with other people's work.

Maybe, if I would trust the history functionality I would learn to use it, now I just feel it is the source of all my problems with Fusion 360, and there is a lot, it is not stabile at all, and every update brings new problems.

 

In any case I think there should be a command to clear all history, like happens when saving to STEP and loading back, but without need to fix everything STEP format did not support. And there should be a way to delete selected sketches, without destroying the model.

2 things.

 

Make your model without sketch.

Do not delete sketch!!!!

 

Might help.....

If you can share your design we can look into the root causes.  You can easily share the public link to your design directly by clicking by right-clicking onto the design in the data panel and choosing the appropriate menu entry. Make sure to enable download.

Trust? I don’t use “trust” in my work, only logic.

If it does not work as expected and causes problems I do not trust it, it is a toy for mee and I use tools for work. Sadly I have used a lot of time an money for Fusion 360, and it would be just too inconvenient to look for other alternative and transfer everything to it.

 

So I keep saving as STEP to get rid of the crap. Really sad functionality.

 

You can see on the above videos what happens, this is happening for me so systematically that I have hard time believing others are not having this kind of problems.

 

The file I will not share publicly

Hi,

If it is a general problem, as an experienced user you certainly have no problem to recreate and share the situation.

Oh, others occasionally do have that problem. However, in the vast majority of cases once we've had a chance to inspect a model it turns out that the problems sits in front of the keyboard.

 

 

I've inspected hundreds of Fusion 360 designs including some complex assemblies.  I can see a number of things of concern in the timeline.

 

  1. There is no joints folder in the top level of that design indicating something is not properly joined.
  2. I see a bodies folder in the top-level which indicates structural problems that will become apparent during assembly. 
  3. The timeline contains too many capture positions, move, and offset features.
  4. The timeline seem excessively long for the little bit of geometry visible in the viewport given that a number of assemblies are linked it.
  5. Also, there is at least one red highlighted error right at the beginning of the timeline.

 

If you don't want to share your design, however, you are on your own as there is no further assistance we can provide.

First of all, I do not use Fusion 360 as a modelling tool, I use it a design tool to make first prototypes, test ideas. Subcontractor usually does the actual modelling and at the same time takes care it is well suited for the manufacturing.  So there is plenty of moving, reshaping, deleting objects. Also there is no joints. and I keep plenty of stuff in bodies as it is just much more easier to access the bodies there. 

 

"5. Also, there is at least one red highlighted error right at the beginning of the timeline." I have no idea what that is, why Fusion 360 generated such error.

 

I would like to keep subassemblies as separate files, but there is so much problems related.

 

My question however is, why would any of this cause the problems I have. So do I really have to use joint, not bodies on bodies folder, limit the number of capture positions, move, and offset features on bodies folder, somehow keep timeline short (how, now I save as STEP and reload to empty it, I hope there would be more user friendly way) etc. for Fusion 360 work properly, Is this really the reason a task like updating a linked file or deleting fails so miserably as one the above videos. And this is called user error by Autodesk.

 

Why is so difficult to give in addition to delete a remove tool for Sketch, that just would remove the sketch, not trying to change every thing it was used for. Tool to empty history (Timeline), without saving first as STEP and then loading back. I think this would solve most of my problems.

There is plenty of other irritations too, that distract me when designing with Fusion 360, like the new selection feature. In general it always wants to select some non visible line, and on the latest versions it has been very focused inserted models, not selecting the very obvious main model line in front, but rather anything from the linked file, until hiding it. Is there some idea with this kind of feature?

 

It seems you are always confused with the selection tool, always some changes to it, except the very obvious. Select only visible lines or faces and select the closest.

I understand where you are coming from. The disconnect is that you don't appear to understand where the majority of other users in this thread are coming from!

 

You are not using the functionality of Fusion 360 the way it was intended to use and make a number of statements that lead me to believe that you have not taken advantage of the tutorial courses in the Learn & Support section. I would strongly urge you to do so.

 

I wonder where you draw the distinction between "design" and "modeling". One can certainly create designs without any digital modeling. That might involve various forms of hand drawings or physical models but as soon as you start using CAD software that starts with modeling. Most of your timeline features are modeling features.

 

Also, you clearly don't understand the distinction between bodies and components, which is a key essential when working with Fusion 360. As soon as you insert another design into the current design you are inserting a component. Unless you ground every component, using assembly joints is essential to properly locate and orient the individual components and sub-assemblies. Not doing that and relying entirely on move and capture position features is also the reason that your designs "explode".

 

You can, of course, turn off the timeline and that will eliminate some of these issues, but has other ramifications. Before continuing, again,  I would strongly recommend going through the tutorials in the Learn & Support section. 

 

The other "distraction" you describe is called "through selection" and is usually very helpful. However, that can be turned off in the selection filters. That, by the way, is not a new feature. Fusion 360 has functioned this way for years!

Kim, dont try too hard to make it work. I spent over a year working with Autodesk support on similar problems, and they just scratch their head and say "We dont know what happened" The problem is that Fusion 360 is really still in Beta test, so your designs are always going to be at risk of falling apart at anytime, for any reason, and no one will be able to help. The best help I get is from these guys here on the forum (seriously they are way better than Autodesk support) so hopefully they can get you on the right track. I just want you to be aware that your problem unfortunately may never be solved.

Before making more inflammatory posts, at the very least you need to read the entire thread and try to understand what the problem at hand is, which you clearly have not done.

 

The problems you are experiencing with your design are not the same at all and dissuading another user who hasn't even begun to understand how parametric modeling works from using Fusion 360 is really uncalled for!
