Description
Allows testing of the function used to define a scripted surface by iterating a ray with a given direction to a specified point, (X,Y,Z). The value of the function and its derivatives are presented for verification.
Navigation
This command can be accessed by clicking on the "Test" button on the Implicit Script Surface dialog box.
