QUERIED DIMENSIONS SHALL BE RESOLVED TO $PRECISION DECIMAL PLACES

Variable Name

Precision

Variable Type

Integer

Display Status

Optional

Comments

According to ASME Y14.41-2012, par. 6.1.1.c, you must provide a note that indicates the precision of the data set. The number of decimal places required for the design cannot exceed the precision of the design model. Typically, a value of 2 is used for parts modeled in millimeter units, and a value of 3 is used for the parts modeled in inch units.

Note Text

UNLESS OTHERWISE SPECIFIED, PART IS MODELED AT $CONDITION

Variable Name

CONDITION

Variable Type

String

Display Status

Optional

Comments

This note should be included for model-based designs (but is not required on drawings). Possible values include minimum, maximum, mean, or midpoint. This note is intended to clarify the state of dimensions that are specified with limit values. In most cases 'dimension midpoint' is probably the best value for the CONDITION string since the nominal dimension is assumed to be the midpoint of the specified limit values in Creo.

UNLESS OTHERWISE SPECIFIED, $GENERAL_PROFILE_TOL APPLIES TO ALL SURFACES

Variable Name

TOLERANCE

Variable Type

Real Number

Display Status

Optional

Comments

Profile of a Surface tolerance with the indicated value with respect to the predominant DRF is specified in the note. This note fully constrains all surfaces that are not referenced by any of the specified features.

UNLESS OTHERWISE SPECIFIED, DRAFT ANGLES ARE $DRAFT

Variable Name

DRAFT

Variable Type

Parameter ID

Display Status

Optional

Comments

When this note is displayed, if the draft angle of a feature matches the value of the specified parameter or dimension, the value is not shown in the dimension annotation. For example, a Tapered Hole feature with a 'Draft Size' scheme in which the draft angle of the feature matches the value in the note will have an annotation of the form 'Ø10±0.1 +DFT'.

Note Text

SHEET METAL STOCK THICKNESS IS $THICKNESS

Variable Name

THICKNESS

Variable Type

Parameter ID

Display Status

Required for sheet metal parts

Comments

This note is required for sheet metal parts. You should specify the ID of the sheet metal thickness dimension for the THICKNESS variable.

Note Text

UNLESS OTHERWISE SPECIFIED, TOLERANCES APPLY IN RESTRAINED STATE AS SPECIFIED: \ $RESTRAINED_STATE

Variable Name

RESTRAINED_STATE

Variable Type

String

Display Status

Required if 'Non-rigid' option is selected

Comments

The value for RESTRAINED STATE should include a brief description of the restraint condition. Typically, the restrained state description references notations on the model that indicate clamping locations and may include specifications for minimum clamping forces.
