Customizing the General Tolerance File

You can customize the general tolerance file used in DimXpert to conform to your specific design requirements.

To customize the general tolerance file:

  1. In the folder specified in System Options > File Locations > DimXpert General Tolerance File, use Microsoft Excel to open general tolerances.xlsx.
    The file contains the following sections:
    Linear Specifies ranges and tolerances for linear dimensions.
    Broken Edge Specifies ranges and tolerances for chamfer and fillet dimensions.
    Angular Specifies ranges and tolerances for angular dimensions.
    Units Specifies the units of measure for linear and angular values in the table.
  2. Under Units, set the units of measure for values in the table.
    If you use the general tolerance file in a model that uses different units, the values are automatically converted to match the model's units.
  3. Customize values in the file.
    For example:
    1. To modify Custom1 for linear dimensions, locate the Linear section.

    2. Change the values in the Custom1 row.
      For example, to change the tolerance from 0.2 to 0.3 for linear dimensions that are in the range over 6 and up to 30, you change the corresponding Custom1 value from 0.2 to 0.3.

    Formatting in the general tolerance file must be maintained. If you change formatting, the file is not recognized as valid, and default values are used instead. For example, do not rearrange cells or leave cells blank.
  4. Save the Microsoft Excel file.
    You must load the general tolerance file every time you update values in it or change its location.
  5. To load the file:
    1. Click Tools > Options > Document Properties > DimXpert.
    2. Under General tolerance, for Tolerance class, select a custom class.
    3. Click Load Custom, and then click OK to confirm your selection.
