Limits and Fits Tolerances

Limits and Fits tolerances are supported for Metric units using the ISO 286-1 and ISO 286-2 standards. Refer to these standards for a complete description of Limits and Fits tolerances.

You can apply Limits and Fits to metric dimensions for Holes, Shafts, and opposing planar faces (that is, face normals point toward each other).

Note: If the dimension is created by selecting an edge, the Limits and Fits tolerance type will be available ONLY IF the system can uniquely determine the parent faces. If there is ambiguity, Limits and Fits may not be available as a tolerance type.

Note: Limits and Fits will NOT be available if the dimension (that is, Basic Size) is outside the range of sizes covered by the standard.

Limits and Fits tolerances are specified with a letter and a number that refer to a table in the standard.
