Import Inventor files (.iam, .ipt) and design history

[Anonymous]

Hello,

I've been evaluating Fusion 360 and OnShape to our engineering needs (along with traditional MCAD packages). Although Fusion 360 takes a slightly different approach to assemblies and constraints, I am starting to get used to the workflow.

One question I have is related to importing IAM and IPT files. There's no issue bringing them in but I am noticing that they import with design operations history in the browser (extrude, fillet, shell etc..). Unfortunately these seem to be artifacts from the Inventor file as they are not editable (some items like fillets are editable but not extrudes etc.). When I turn on 'Capture Design History' the operations are absorbed into a Base Feature which is normal.

Is it possible to import IAM and IPT files with editable design history?

If not, what is the reason for the history being imported if they are not editable?

Thanks for any insight!

I don't think Fusion is reading the history from the file it's just making a direct modeling version of the import and running Find Features as it imports.

Have you tried modeling in Fusion with Capture Design History off it might give you a bit more idea of what possible or not in direct mode.

I, too, have noticed some quirks when importing files from Inventor.

While I did not create the original parts or assembly, there were significant differences between the location of components in the original Inventor model and the one Fusion imported.  In the end I re-created the models and assembly.  Not ideal, but it worked.

Interesting. So import IAM/IPT files seems to invoke the 'Find Features' automatically. I did the same import with a Solidworks file and had to use the 'Find Features' command to create the features. This was all done in direct mode as imports start in that mode by default (unless there's a way to default to history mode).

On that note, the features in the browser are not really a history but more of a 'feature identification'? I thought they may have been features from the original model built in Inventor and could be modified. This would be awesome but I realize the 2 products aren't that tightly syncronized 😉

To the poster above: When you say Inventor assembly locations don't match, do you mean component tree locations or actual physical location?

Thanks for your help.
