Configuring dimension accuracy and tolerances in Excel

configuring tolerances

W configuration table Tolerances can be controlled as follows:

  • W parts you can control dimension tolerances in sketches and features.
  • W assemblies you can control the so-called dimension tolerances. assembly operation. This includes bindings (angular or distance), assembly feature cuts and holes, and component patterns. You cannot control the dimension tolerances of a component contained in an assembly.

The column header in the tolerance control configuration table uses the following syntax:

$TOLERANCE@parameter name

 

E.g:

  • the depth tolerance of the extrude feature is: $TOLERANCE@W1@Extrude1,
  • distance bond tolerance is:$TOLERANCE@K1@Distance1.

configuring tolerances

When entering values ​​for tolerances in the design table, use the following keywords and the syntax shown.

  • LACK
  • BASIC
  • MIN.
  • MAX

    DOUBLE-SIDED = max_variation;min_variation
    LIMIT = max_variation;min_variation
    SYMMETRIC = max_variation
    FIT = class;hole_match;shaft_match;match_type;max_variation;min_variation
    FIT_WITH_TOLERANCE = class;hole_match;shaft_match;type;max_variation;min_variation
    MATCH_TOLERANCE_ONLY = class;hole_match;shaft_match;type;max_variation;min_variation
    tol_precision

where:

max_variation is positive tolerance.
min_variation is negative tolerance.
class is a general classification.
