Question: How do I change the geometry of this parametric model?

The model is defined by four variables, that can be changed to generate new variations of the geometry.

  1. Step 1:

    Go to Insert->Tools->Equations to open the dialog box showing equations and variables.

  2. Step 2:

    Here you see the equations I have set-up in this particular model.

  3. Step 3:

    Change any value and observe how the geometry changes when the model rebuilds.

  4. Step 4:

  5. Step 5:

    You can create some pretty groovy variations...

  6. Step 6:

    ...but be aware that some values will destroy the geometry. In that case re-open Equations and change back to the default values.

  7. Step 7:

    The default values are 60 degree angle, 200 mm spacing, 3 blades and 750 mm diameter.

  8. Step 8:

    This is the default model.
