Importing Assemblies and Maintaining Association with Individual Parts

Anonymous
Not applicable

I have searched the forums for an answer to the below question but have not found it:

 

I have been working in ProE/Creo for the past decade and for personal use have started using Fusion 360. I have done considerable design work I would like to start migrating over to Fusion 360 that is my own; however, importing into Fusion 360 does not function as I would expect (i.e., the same as ProE does).

 

When I import a step file into ProE, it creates the assemblies and it also creates the parts with their association to the assembly. That way, if I open the individual part and modify it, it is modified in the assembly.

 

When I import a native ProE assembly or STP file into Fusion 360, I get the choice of importing the assembly or the individual parts. If I import the assembly, it creates the assembly, but not the individual parts (i.e., they are not in my data panel) and it appears I cannot open the individual parts from the assembly without doing a save copy. After doing the save copy, you lose the association with the assembly but it is then available in the data panel.

 

Am I missing something here?

 

I want to be able to import the assembly and have the parts available in the data panel so I can open them, modify them, and see the update in the assembly after I open it.

 

Thank you,

Graham

Yes, you are missing something 😉

 

In Fusion 360 you can create a complete assembly in a single file. As such, when you import STEP assemblies all components and the assembly structure are created in a single Fusion 360 file/design. It is also created in Direct Modeling mode by default and if you want to record the design history you'l have to enable it.

New designs are created with the timeline (design history) enabled by default.

 

Having that said, I've worked in many CAD systems over the last 30 years. One mistake I see many experienced CAD folks do is to start using a new CAD system that seems to resemble their old system and start working based on the expectation that it'll work out.

But often that leads to problems that could have been prevented by watching the 60 minutes or so of introductory tutorials in the Support and Lerning section.

Your reply confirms my concern. Having everything come in as a single file without creating the subsequent piece parts individually in the data center is not a positive. Additionally, thank you for implying I did not research before asking the question and then not provide a meaningful response. Hopefully, your thirty years of experience can be helpful somewhere else.

Why is that a concern and not positive ?

1. No, you are not missing anything - that is the way Fusion 360 works.

 

2. Autodesk Inventor works the way you describe.

30 yrs CAD experience and you don't understand why that is a concern and not a positive?

Just saying!

Peter, I respectfully disagree. We already had some private conversations about that topic and I would like to continue in public because here is another typical case.

 

In my opinion, the approach of Autodesk and the Community is giving a misleading impression: "download Fusion 360, read some learning stuff, watch some videos and start a project". Fusion 360 is soooo easy to use. 

 

You know about my background and experience. It did not work for me. It took me more time until I really understood the concept and philosophy (addendum/edit: and the current limitations!) and how to use it efficiently. Much more time.

 

The concept of Fusion 360 is great, it´s a versatile tool. But versatile software tools need a basic amount of training and experience. A couple of videos are not enough.

 

But maybe my brain is just too old and stupid.

@Anonymous my apologies for my snotty mouth! I am also getting older and maybe more stupid  by the minute 😉

 

@Anonymous Agreed!

I actually started watching some of the introductory material myself, in particular the Fusion 360 mastery course.

I wonder what audience this is aimed at, but it is clearly not professionals. the first 10-15 minutes are so laced with marketing hyperbole that I have to take a break in between. Then there are a few good segments and then it continues with marketing.

Very few of the tutorials actually provide explanation of basic concepts. That slack is usually left for others to explain. The materials that explain transitioning from Solid Works are leaving out some of the first steps I see so many people step right into.

It forces me to work on the piece parts in the assembly. If I want access to the piece parts outside of the assembly with the modifications I made while in the assembly, I need to do a "Save Copy As". After I have created a copy of the part outside of the model and make changes to it, I would have to delete the old part and reassemble the copied part back into the assembly to see those changes. This is inefficient, especially with a model composed of 193 parts and that is one of my smaller assemblies. Essentially, it forces me to reassemble the entire model so I can have a link between the individual parts and the assembly. From experience, I know this does not have to be the case but apparently, with this product it is.

I downloaded and use the PDF manuals. They are better.

Yes,  that won't work and I can see that in larger assemblies this is not a workable solution.

 

Fusion 360 started as a direct modeling software and the timeline was added later. Back then it was advertised as "design differently" mostly to connect (product) design, mechanical engineering and CAM, so the workflow from ideation to making that is usually very disconnected with each of the disciplines working with their own software solution.

 

But AD had discovered that mechanical engineering and machine design are a large market segment and have changed direction, so now competing with Solid Works in that market segment is pursued very aggressively.

 

Fusion 360 strength is top down design. I use it very effectively to create concept models for manufacturing automation solutions. I don't have to provide a lot of detailed mechanical design, but convey a concept, so the ability to quickly create acceptable concept models in single file is great.

 

However, there is no way Fusion 360 would be able to replace Solid Works , or Autodesk inventor - at least not now - for creating a "real" machine design in that industry. In my experience machine design, particularly automation solutions are 90%+ bottom up. That is really NOT Fusion 360's strongest suit.

 

Why it's being advertised as such remains a mystery to me!

 

If you have a assembly of 193 parts and that is one of your smaller assemblies, then Fusion 360 might not be for you. The usual rule of thumb is that Fusion 360 will get sluggish past 1000 components.

 

May I ask what sort of designs you create for personal use that have that many parts ?

Ok so 360 software has a different base code logic than solidworks or inventor.  What's the work around For 360 to simulate SW or inventor associated files?  My circumstances have changed.  I had access to SW for personal projects and now I don't.  360 is the best alternative to continue my project.  There must be a design process within 360 to maintain the file association, even if it's a manual process.

Can you be more specific as to what you want to do ?

What do you mean specifically with "file association" ?

Do you want to import assemblies from SW to Fusion 360 ?

Just curious. Why is 360 the “best alternative” for you?

Have you found workarounds, because I have exactly the same issues? 

If you have linked files in your assembly Fusion 360 does not allow you to modify them in the assembly so you have no visual reference to get ex. holes, screws.... to line up and there are no constraint tools to line things up dynamically. Then the total miss comes in when you want things to be manufactured.

If you want to be able to design, modify and test your assemblies and sub-assemblies you need to break all links, and then you cannot establish linked files between the assemblies and manufacturing work spaces. 

A save body as linked component is a desperate need.

That you cannot go from working on an assembly to making a fixture for producing the parts removes SO much of the promise that this application has of an integrated design and manufacturing environment, or rather you can only do so by creating islands of unconnected components, version and revision history

Is there an easy to import assemblies, modify parts in Fusion and get them into manufacturing while maintaining links?

That can be done with "Derive". This allows you to derive a component out of the assembly into the data panel.

The derived component will maintain its links to the assembly, so every change to mea o the component in that assembly will be reflected in the derived component.

 

Then in that derived component you can change into the manufacturing workspace and create you set-ups and tool paths. Thus you won't have your assembly file overloaded with all of he manufacturing related data.

Thanks! 

That seem to help a lot, though I cannot get a proper grip on whether it creates 2 way sync or just one way

I believe one way: Assembly->Derived Component.

@ryan.bales can you confirm ?

Yes one way. It can be explained by this:

 

DesignA is the assembly, Design B is the "derive"

 

We Derive in Design B into A and any changes in the Derived model (Model A) are not sent back.

Just so all parties are aware - Edit in Place is coming for linked designs and those changes ARE two way. Very cool if used wisely.
