Missing Features When Editing Another Component

[frogydiak]

I have Multiple Components created for each parts of my project for example:

Component 1

Component 2

Component 3

and so on. I am editing Component 3 but forgot something so I have to update Component 1 and added a feature. Then I go back to Component 3 and edited a Sketch but the new feature that I just added to Component 1 is not visible in the Sketch I am editing which I needed for reference. Is this normal with Fusion 360?

Thanks!

Hi,

1. Compute all

2. Please share the file for reply.

Here is what I mean, if you notice I have something above the Drawer Lock but when I edit the Sketch that feature above it disappears. I already did Compute All but it is still disapper.

Hi,

If a feature is based on a sketch*, it “disappears” when you reactivate this sketch for editing.

I can't tell from your screencast what happens.

*the sketch is in the timeline before the feature

Hi,

When you say you forgot something and went back and fixed it, did you do this by using the timeline or just bang it

in and move on? Fusion is very picky about the order things are done in the timeline and if you don't manipulate it

correctly then it will not work properly. The timeline is very powerful when used as intended.

I also notice that the sketches you have are quite complex. You are far better off using simple sketches to create a

basic piece of geometry and then use the tools to model it correctly. The more complex a sketch is the more likely it

will cause you problems and the easier it is to break. The sketch that is visible is not fully constrained and this is not

a good thing either.

When you say the new feature you added to Component 1 is not visible in the new sketch, did you project the new

geometry into the new sketch?

Are you able to attach the file for us to look at? If it is proprietry can you knock up an example of the behaviour and

post that? Can you give us a screenshot of what is happening? I cannot really see the problem in the screen cast.

Cheers

I'm new to Fusion and still learning. Does it mean that Fusion will only make features in each components visible at the same timeline when that features are created in each component? That doesn't make sense. But I guess I am not doing it right.

What I did is, I moved back to Component 1 (made it active) and added a new Sketch then I activated the new component again and edited the sketch that I am working on but every time I do that, the geometry I just created in Component 1 is not visible so I cannot project. Oh wait, you mentioned project, so when I first created the new component, I did project but since I forgot a feature in Component 1, I went back to it and created it. So, since I projected on the new component earlier on, then a newly added feature should not be visible? If that's the case, then what should I do to update the projection and make the new feature visible?

I am trying to project the new feature I added in Component 1 in the new component geometry sketch but it is not visible. I wonder if there is a setting that could override this behavior and make all the features in sync.

this is the way that Fusion works with multiple components in a single document.  There is only one timeline.  When you edit a sketch or feature at some point in the timeline, the timeline is "rolled back" to that point in history.  Everything to the right of the point of edit will no longer be seen in the model.  It is just the way that history-based designs work.

Hello! Thanks for confirming that. So, if that is the case, then how do you solve that issue that I have? Are you saying with the default Fusion behavior, the top component can't be modified or have to be complete, otherwise, that modification will never be visible to the lower or new components in the tree? I don't get it, so, how do you go back to your design and augment any mistake or make any modification? You have to re-sketch? 😕 

What should be the best workflow in this kind of project? Use 1 component and just create a new body to separate each component?

Time travel is possible, but only in Fusion😁

If you need to add a feature based on something later in the Timeline, you can create a sketch at the top level and project the geometry to it (Uncheck Projection Link).  After saving the sketch, you can move it back in the Timeline. 

The other option is to simply add it to the first component after the referencing geometry was created in another component.  You can't add it to the original sketch except by time traveling.

Yet another option is to edit parameters if you just need to change dimensions or locations.
