FF/FL Define test surface

This step helps to define the test surface and the FF/FL values to achieve.


  1. Either define a test surface aligned or not to the current UCS (press SPACE to change the mode): use the scene to draw it.

  2. Define the Specified Overall Flatness and Levelness values: that is to say for the test surface and the test sections.

  3. Optionally, define Minimum Local Flatness and Levelness values: that is to say for each sample line.

Notes

  • The test sections defined in the next step will have to be inside the test surface.

  • In case of a single test section, you can define directly its position in this step.
