Some that are using the new 2010 have noticed that new Solid bodies folder in the part modeling browser. This tool allows us to specify different features inside a single part as unique solids. Before Inventor 2010 all features that were modeled in a single part existed to create that sinlge part. Mass properties and inertial properties were calcualted on all the geometry in that part file. With the New Solid option inside of the common 3d features like Extrusion, Revolve, Loft, Sweep, etc you can specify multiple solid bodies in one part file, instead of them automatically joining as they have in the past. Also new is the the Make Components command that works great with the Solid Bodies feature. You can use the Make Components command to take all those solid bodies from the single part and turn them into parts of an actual assembly. Imagine a combination of some of the more complex derived component and skeletal modeling approahces that some of us have taken in the past. I am currently talking to a number of users about how this will help in creating some of their more complex assembly designs. For a quick example of the workflow required. Take a look at the video below.

This past week I was ask by a company who does some mold design and also a lot of part cradles, what functionality inside of Inventor would allow me to do this. Well the answer is using derived components. My example is very simple consisting of a upper and lower portion of a mold and an item I would like to create a mold from. Of course this is just a couple simple blocks that don’t have all the detail as a proper mold would like dowel holes etc…

The following link contains an example of the new capabilities Inventor 2008 provides with its new “Export Geometry” tool used in conjunction with the updated “Derived Component” command. These tools enable a Skeletal Modeling workflow in which a change to the Skeleton will only affect the components using a specific set of derived geometry or parameters from it.
You could hypothetically have a skeleton with hundreds of parameters in it, and have hundreds of parts linked to these parameters in an assembly. When the skeleton is changed, only a small number of parts would need to “Update” in Inventor. This allows the technique to be used with much larger assemblies, and makes them much easier to manage in Autodesk Vault. Check out the example in this link:
