Background
Hi. I'm new to Autodesk Inventor and I was using freecad in the past.
I made parts of the robot I want in freecad and exported to obj. I then imported to autodesk inventor and tried doing assembly and I noticed an error in my original freecad design. I fixed the error and tried reimporting the obj but it keeps the past obj file that was imported unless I change the name of the obj file. The current solution I have is to create a new assembly project each time I noticed a mistake in the design.
Question
Is there a way to import an updated obj file with the same name without creating a new assembly file each time?

It sounds like you would like the OBJ file to update the Inventor model. (If you simply "import" then Inventor will treat each import as a completely new part/assembly.)
Inventor can link (as opposed to import) certain 3rd party file formats - unfortunately OBJ isn't one of them.
If you export a STEP file from freecad, then when you bring it into Inventor you will be presented with the option to link the file. This means you can go back and edit the model in freecad - export over the old STEP file - and the Inventor model will show the update.
Hi. I exported to .step file and imported both the old and new versions of the step file but I didn't get asked for the option to link and I got the old file instead. This also happened for the file that I previously imported as a .obj with the same name. Is there something I'm missing?
When you first import the Step file, you select this:
The step file appears as a part/assembly - but the browser icon indicates that it is a "Reference Model".
Modify the original model. Save the changes to the same Step file (so you overwrite it - don't create a new one).
Switch back to Inventor and you'll see this lightening strike beside the reference model indicating there is an update available:
Update the model (lightening strike icon on the toolbar right at the top of the screen), and the modified step file appears:
