# As-built tolerances

Default as-built tolerances can be defined per project, making it a little easier to check whether something is built within tolerance. These settings can be edited during a session, if the tolerance varies between different surfaces.

There are two things that need to be filled in:

* Tolerance&#x20;
  * Z minimum&#x20;
  * Z maximum
* Colors
  * Color below tolerance (negative value)
  * Color within tolerance&#x20;
  * Color above tolerance (positive value)
