How do I select a single body?

[Anonymous]

Hi, I'm very new to Inventor and have a simple question. I have a document with two bodies. I would like to move one of the bodies from its current location, but I'm unable to. If I click the green botton on top, in the option 'Select bodies', both of the parts are selected. If I click on 'Modify' > 'Move Bodies', it also selects both bodies, and the cursor to manually select the bodies is disabled. Could this be because I have constraints that I'm not aware of? I'm attaching the file. Thanks!

Looking in your history tree - you have only a single disjointed body.

Right click on the Revolution1 and select Edit Feature.

Select the New Body option.

In Inventor a part is a part (just like the real world) - file format *.ipt (Inventor Part).

In Inventor an assembly is a collection of parts (or sub-assemblies) as components (just like the real world) - file format *.iam (Inventor Assembly).

It looks to me like you really intended for this to be an assembly of two (or more) parts, so I would create these as separate parts (just like the real world).

You could do this as multi-body solids in one part file, but I don't think that is your true Design Intent.

edit: Ha ha.. I see JD modified his post and now I'm like a Parrot... 

As stated your part only has a single body (even though it looks like 2 you modeled them all under the single body.. disjointed).. (see the solid bodies folder in the top of the model browser) 

I think you may be going about this incorrectly though.. 

While multiple solid bodies is something Inventor can accomplish and is used often I would think that as a new user what you really wanted to do was model 2 parts (ipt files) and then create an assembly (iam file) of those parts vs trying to do everything in a single part file. 

Multibody modeling techniques are a more advanced functionality in Inventor and not something I would recommend a new user start with..

Each "real world" part should get its own "part/ipt" file in Inventor and then you place those parts into an assembly file and constrain them just like in the real world..
