2. Key takeaways

1

Before the first sketch, identify the dimensions that will change: these become global variables.

2

Link dimensions to variables with equations: a single value change updates the whole part.

3

After each change, rebuild and check that every feature has updated correctly.

4

Apply the right material before reading the mass properties: without it, the mass is meaningless.

Tip

Set the document units and number of decimals before you start: you will read the mass directly in the required format.

3. Do the exercise

Model a parametric plate:

  • create three global variables A, B and C for length, width and thickness
  • add a hole, a fillet and a chamfer linked to these variables
  • apply a steel, note the mass, change A and note it again
✓To check: Changing variable A updates the whole part with no rebuild error, and the mass changes in the expected direction.
