Tolerance Type |
You can choose from the following types for showing Fit tolerances:
- Fit
- Fit with tolerance
- Fit (tolerance only)
If a value of zero (0) appears for a fit tolerance, it indicates that the dimension is outside of the range covered by the applicable standard. For example, the ISO standard for G9 and G10 fit tolerances does not provide tolerance values for dimensions greater than 50 mm.

| Within range |
Out of range |

Classification |
You can choose from the following classifications. The shaft and hole tolerances available are filtered to correspond to the classification.- User Defined
- Clearance
- Transitional
- Press
|
  |
Hole Fit and Shaft Fit |
You can choose standard Fit tolerances from the hole and shaft lists. The software automatically verifies whether the standard is appropriate for the dimension. When you select either a hole or a shaft Fit tolerance, the list for the other type is filtered to present only corresponding tolerances. The bilateral tolerances are also calculated automatically. The Classification aid for selecting an appropriate Fit designation is either Hole Basis or Shaft Basis, depending on which Fit designation you choose first. As Hole Basis and Shaft Basis Fit classifications in the international standards are not fully bidirectional, you may get a different list of suggested Fit choices (or an empty list) depending on the order in which you choose your designations. Hole Basis is preferred for most manufacturing processes.

Automatic Versus User Defined Tolerance: The advantage of letting the SOLIDWORKS software calculate the bilateral tolerance values for you is that if the dimension changes, the tolerances are updated automatically. To specify tolerances manually, click the Hole Fit or Shaft Fit icon and type values in the Maximum Variation  and Minimum Variation  boxes. Select Show parenthesis to insert parenthesis around the tolerance values (Fit with tolerance only).

Fit Tolerance Display |
For Fit or Fit with tolerance with both hole and shaft tolerances, you can select a display style.- Stacked with line display
- Stacked without line display
- Linear display
With Fit (tolerance only), the Fit standards are not displayed.
