Assignment – Parametric Fuel Tank
Create a model of a rectangular fuel tank. Use the expressions editor to create the variables that will contain the following dimensions:
- These variables will be determined by the customer:
- LENGTH (in inches)
- WIDTH (in inches)
- CAPACITY (in gallons)
- The height will be calculated from the volume of the tank:
- VOLUME (in cubic inches)
- HEIGHT (in inches, calculated from the volume)
