  1. Parametric Design Principles Benefits Initial thought concepts Design principals Example – Fire Truck Compartment Whole assembly principals Example – Fire Truck body

  2. Benefits to Parametric Design • Time • Money • Reliability • Ease for new users • Easier to copy out Example  Old way = 4hrs./day New way = 4x normal and 1 hour/day In the end; Old way = 200hrs New way = 65hrs

  3. Requirements for parametric design Is this an assembly very similar to previous assemblies? Are the items that change dimensional? Do items need to be added or taken away? Is this a build that varies by customer? Is the design intent stable? Can you reuse the design and make modifications? Are you interested in a general form that someone can fill out and it give you 80-90% of the design? Initial Thought Concepts

  4. Design Principals • Sketches • No more than 5-6 dimensions per sketch • Sketch relations are key… the more you have, the happier you’ll be! • USE THE MAPS for relations • Label everything!

  5. Design Principals • Model Features • Label everything!!! • Relate bosses and cuts to maps or other features related assembly components • Make sure all models are “tied” together with references for easier Pack-and-Go operations

  6. Example Time Let’s take a look at a compartment on a fire truck. Notice how anyone can change every aspect of the compartment by changing any of the 3 dimensions.

  7. You can have multiple maps Multiple maps mean you can have many assemblies that can be turned on and off Tie everything together When you Pack and Go, start with the topmost assembly Label everything! Create a “Master” model that you can derive everything else off of. Take your time to encompass all options. You will forget some things depending on the complexity, so just add it to the Master model. Assembly Design Principals
