You can use functions to create curves from mathematical relationships that you define.
To create a curve using a function:
- Select Construct tab > Curves panel > Other Methods > Functions to display the
Functions dialog in one of these ways.
- Select the type of
Function you want from the menu.
Note: The variables
a,
r,
t,
x, and
y are local to the
Functions dialog. Any previous values that you have set for these variables are ignored. However, you can use any other previously defined variables. As well as variables, you can use any predefined functions or constants discussed under Equations.
Warning: Trigonometric functions are often used in constructing these functions. Be careful to use
sind(),
cosd(), and so on when using degrees and
sin(),
cos(), and so on when using radians.
