My work uses Autocad Inventor so I get them to sent me the odd file so I can see how our Draftsmen make the assemblies up but I can only open the STEP files and not an iam. file.

Have looked on you tube but haven't been able to work it out.

Also I am making a jig for work but after making a part and adding it to assembly mutable times, I go to use the Tab and Slot feature and it adds the Tab/s to the parent part but only slot/s to first part. How do I make slot/s for the other mutable parts in assembly?

Have tried different things but can't work it out.

Thanks for any help you may have. 

I have Student version.
