New to the upcoming Inventor 2009 is an option in the “Angle” assembly constraint called “Explicit Reference Vector”. This allows us to define a direction perpendicular to the rotation direction and thereby enforce the “right hand rule”. Check out this video for an example:
Well help is hear TODAY!! Yes we can insert groups of parts right into the assembly file and then start placing constraints to hold them together.
We can either multi-select from the place component dialogue box or we can also drag and drop from a Windows Explorer file list.

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:

Year after year I still bump into a few Autodesk Mechanical Desktop Users floating around. So I wanted to create a list of features that I thought really makes the jump well worth considering if your still using MDT. Feel free to add some of your own by posting a few comments.
Assembly Modeling – Part 1:
1. Drive Constraints – This command allows you to take your assembly constraints and show them in motion to better understand how your concept will function.
2. Contact Solver – This tool allows you to have your parts physically stop or move as they bump other components.
3. Flexible Status – The ability to have a sub assembly placed multiple times but function as it does in real life independently of the others.
Also down in the file sharing zone below on this blog I have uploaded a white paper on how to move some of your MDT data sets forward into inventor. Link to PDF.
