This is a tutorial to get you started with using mathematical equations to sketch curves and makes surfaces/solids using them. You will need version 5.0 or newer of DesignSpark Mechanical to access this advanced sketch mode. The video was created in partnership with ANSYS Inc.

Here is the syntax and list of pre-defined functions::

- Parameters include a name and are enclosed in square brackets [L]
- Functions include a function name followed by parenthesis containing any values as arguments
- For example: Sine([t]-[r])

- The table below shows common predefined intrinsic functions included
