Precision and Tolerance dialog box

Sets the precision and tolerance attributes for hole, chamfer, or bend notes.

Access

Ribbon: Manage tab Styles and Standards panel Styles Editor . In the Style and Standard Editor, click to expand the Dimension style in the browser. In the Dimension Style window, click the Notes and Leaders tab, and then click Precision and Tolerance. Click More to expand the dialog box.

To override precision and tolerance parameters for an existing hole or chamfer note, right-click the note and then select Edit Hole Note, Edit Chamfer Note, or Edit Bend Note. In the dialog box, click Precision and Tolerance. Click More to expand the dialog box.

Options depend on which note type is selected on the Units tab of the Dimension style dialog box.

Hole notes

Use Global Precision

Sets parameter precision to the precision defined by the Precision setting on the Units tab of the active dimension style. When selected, individual parameters in the Precision column are not available. Clear the check box to edit individual precision controls.

Has no effect on settings in the Tolerances column.

Use Part Tolerance

Uses format and tolerance information from the model. When selected, individual tolerance values in the Tolerances columns are not available, except tolerance controls for Countersunk Depth and Tap Drill Diameter.

In part modeling, if a limits tolerance is specified for a hole parameter, the Tolerance and Precision dialog box settings are disregarded. The precision of the displayed parameter reflects the setting in part modeling.

Show All Parameters

Displays all hole parameter rows, regardless of the selected hole or thread type. Overrides the default setting, which shows only parameters relevant to the selected hole or thread type.

Unit Precision

Primary sets precision for hole diameter. Click the arrow to select a precision setting from the list. Not available if Use Global Precision is selected.

Alternate sets precision for hole diameter in alternate units. Click the arrow to select a precision setting from the list. Not available if Use Global Precision is selected.

If Linear Format on the Units tab of the Dimension style is set to Fractional, precision settings are shown as fractions. Decimal precisions correspond to fractional values, such as 1/8 is shown as .125. Format is also represented on Tolerances. An exception for hole notes is countersunk angle (always shown as decimal, unless the Angular Format on the Units tab of the Dimension style is set to Deg_Min_Sec).

Tolerances

Sets the tolerance values for the selected hole type. Check the box next to a symbol representing the hole parameter to set precision and tolerance values.

Upper Sets the value for the upper tolerance. Enter the upper tolerance value.

Lower Sets the value for the lower tolerance. Enter the lower tolerance value with a negative sign of operation. Not available if the selected method does not support a tolerance range.

Method Sets the tolerance method. Click the arrow, and then select from the list.

Precision, Precision (Alt)Sets the number of decimal places to display in the hole note. Values are truncated and rounded to the specified precision. Click the arrow, and then select from the list.

Chamfer notes

Use Global Precision

Has no effect on settings in the Tolerances column.

Unit Precision

Primary sets precision for each chamfer parameter. Click the arrow to select a precision setting from the list. Not available if Use Global Precision is selected.

Alternate sets precision for chamfer distance values in alternate units. Click the arrow to select a precision setting from the list. Not available if Use Global Precision is selected.

Tolerances

Sets the tolerance values for the selected parameter type. Check the box next to a symbol representing the parameter to set precision and tolerance values.

Upper Sets the value for the upper tolerance. Enter the upper tolerance value.

Lower Sets the value for the lower tolerance. Enter the lower tolerance value with a negative sign of operation. Not available if the selected method does not support a tolerance range.

Method Sets the tolerance method. Click the arrow, and then select from the list.

Precision, Precision (Alt) Sets the number of decimal places to display in the chamfer note. Values are truncated and rounded to the specified precision. Click the arrow, and then select from the list.

Bend notes

Use Global Precision

Has no effect on settings in the Tolerances column.

Unit Precision

Primary sets precision for each bend parameter. Click the arrow to select a precision setting from the list. Not available if Use Global Precision is selected.

Alternate sets precision for bend radius value in alternate units. Click the arrow to select a precision setting from the list. Not available if Use Global Precision is selected.

Tolerances

Sets the tolerance values for the selected bend parameter. Check the box next to a symbol representing the parameter to set precision and tolerance values.

Upper Sets the value for the upper tolerance. Enter the upper tolerance value.

Lower Sets the value for the lower tolerance. Enter the lower tolerance value with a negative sign of operation. Not available if the selected method does not support a tolerance range.

Method Sets the tolerance method. Click the arrow, and then select from the list.

Precision, Precision (Alt) Sets the number of decimal places to display in the bend note. Values are truncated and rounded to the specified precision. Click the arrow, and then select from the list.
