Tolerances 

This page deals with the options concerning:

New Size Tolerances Creation

Propose the last created tolerance values

Defines whether the last tolerance type and values defined in a command should be proposed as default for the next command in the Limit of Size Definition dialog box available via Tolerancing Advisor.
By default, this option is not selected.

Angular Size

Defines the angular size options:

Default upper tolerance value

Defines the default upper tolerance value for angular size.
By default, the upper tolerance is 0.1deg.

Symmetric lower limit

Defines whether the default lower tolerance value is symmetric in relation to the default upper tolerance value.
By default, this option is selected.

Default lower tolerance value

Defines the default lower tolerance value for angular size, enable when Symmetric lower limit is not selected.
By default, the lower tolerance is -0.1deg.

Numerical value increment

Defines the increment for angular size numerical value.
By default, the increment is 0.1deg.

General tolerance class

Defines the general tolerance class for angular size, according to the standard of annotation set.
  • If the standard of annotation set is ASME or ANSI, then ASME general tolerance class value will be considered, else ISO tolerance class value will be considered.
  • Based on the selected conventional standard, customized tolerances (ISO, ANSI-ASME, or JIS) appear in the General Tolerance list in the Limit of Size Definition dialog box.
By default, the general tolerance class for ISO is ISO 2768 - f.
By default, the general tolerance class for ASME is ANSI B4.3-1978-f.

Chamfer Size

Defines the chamfer tolerance options:

Default upper tolerance value

Defines the default upper tolerance value for chamfer size.
By default, the upper tolerance is 0.1 mm.

Symmetric lower limit

Defines whether the default lower tolerance value is symmetric in relation to the default upper tolerance value.
By default, this option is selected.

Default lower tolerance value

Defines the default lower tolerance value for chamfer size, and is enabled when Symmetric lower limit is not selected.
By default, the lower tolerance is -0.1 mm.

Numerical value increment

Defines the increment for chamfer size numerical value.
By default, the increment is 0.1 mm.

General tolerance class

Defines the general tolerance class for chamfer size, according to the standard of annotation set.
Note: If the standard of annotation set is ASME or ANSI, then ASME general tolerance class value will be considered, else ISO tolerance class value will be considered.
By default, the general tolerance class for ISO is ISO 2768 - f.
By default, the general tolerance class for ASME is ANSI B4.3-1978-f.

Linear Size

Defines the linear size options:

Default upper tolerance value

Defines the default upper tolerance value for linear size.
By default, the upper tolerance is 0.1mm.

Symmetric lower limit

Defines whether the default lower tolerance value is symmetric in relation to the default upper tolerance value.
By default, this option is selected.

Default lower tolerance value

Defines the default lower tolerance value for linear size, enable when Symmetric lower limit is not selected.
By default, the lower tolerance is -0.1mm.

Numerical value increment

Defines the increment for linear size numerical value.
By default, the increment is 0.01mm.

Default tabulated value

Defines the default tabulated for linear size. While creating dimensions, upper case and lower case letters of tabulated values appear based on the selected element, hole or shaft.
By default, the tabulated value is H7.

General tolerance class

Defines the general tolerance class for linear size, according to the standard of annotation set.
Note: If the standard of annotation set is ASME or ANSI, then ASME general tolerance class value will be considered, else ISO tolerance class value will be considered.
By default, the general tolerance class for ISO is ISO 2768 - f.
By default, the general tolerance class for ASME is ANSI B4.3-1978-f.

Geometrical Tolerance, Datum Target and Datum System

Defines the default numerical values for geometrical tolerance and datum target.

Description

Lets you specify the description of the numeric display. Based on the unit specified in the Description list, the values are displayed for datum targets and semantic geometrical tolerances.
By default, NUM.DIMM is selected.

Display

Lets you specify the number of units in which the values needs to be displayed.
For example, if you select FEET-INC in the Description list, based on the number of units selected in the Display list, the numerical values will appear as below:
  • 1 factor: Numerical values will be displayed in feet only.
  • 2 factor: Numerical values will be displayed in feet and inch.

Precision

Defines the geometrical tolerance and datum target precisions after the numerical separator.
By default, the precision is 0.01.

Separator

Defines the geometrical tolerance and datum target symbols used as numerical separator.
By default, the separator is a dot ".".

Default numerical value

Defines the default numerical for geometrical tolerance.
By default, the numerical value is 0.1mm.

Numerical value increment

Defines the increment for the geometrical tolerance and datum target numerical values.
By default, the numerical increment value is 0.01mm.

Display trailing zeros

Defines whether "0"s complete the number of digit displayed after the separator, according to the precision.
By default, this option is not selected.

Display leading zero

Defines whether the "0" before the numerical separator, when value is less than 1, is displayed.
By default, this option is selected.
