Learning Objectives
At the end of this class, you will be able to:
• Identify the differences between Bottom Up, Top Down and In Place modelling techniques.
• Communicate the benefits of using derived assembly techniques, over the ‘standard’ constraint based assembly technique.
• Understand how to choose which technique (or combination of techniques) to use on your project.
• Understand how to use ‘alternative’ assembly techniques to build constraint free Assembly models.

Before you can model your designyou must design your model
Design Intent
We want assembly models that are:Quick to buildReliablePredictableEasy and quick to edit

Bottom up
Let’s try it…
© 2012 Autodesk #AU2012
Cons:• No relationships between parts• Not easy to build or edit large assemblies
Pros:• No relationships to manage between parts• Easy to create your BOM/Parts list
Bottom up (Traditional)

In Place
Let’s try it…
© 2012 Autodesk #AU2012
Cons:• Adaptive references can be tricky to manage• Not easy to build or edit large assemblies
Pros:• Works with surfaces & neutral format parts• Quick to build – great for goal finding
In Place (Adaptive)
© 2012 Autodesk #AU2012
Let’s try it…
Top Down: Skeletal modeling
© 2012 Autodesk #AU2012
Cons:•Working with just the geometry is not very intuitive•Building part models can be time consuming•Building parts without context = lots to coordinate Pros:•The derived parts are very lightweight•Assemblies can quickly be laid out in 2D to see how they function before time is invested in 3D modeling.

Top Down: Multi body design parts
© 2012 Autodesk #AU2012
Cons:• Must be built in a structured manner – design
intent• Lots of relationships between parts to manage
Pros:• Quick and easy to design complex models• Quick and easy to make parametric edits

The Hybrid approach
© 2012 Autodesk #AU2012
Cons:•Your whole team needs to work in a structured and methodical manner
Pros:•The workload can be shared across the whole department

Modeling Workflow tips
• Plan your assembly (Design intent)• Add your known parameters• Create sketch blocks• Create work features as required• Create geometry to define your design• Name your geometry• Derive geometry out – if appropriate• Model the 3D features/solids• Derive your solids out into assemblies
© 2012 Autodesk #AU2012
Assembly Workflow tips
• Don’t go Multibody mad• Use feature based parametric design sparingly• Keep it simple• Use Inventor for what it’s good at• Faster updates
