Predefined Application Notes (ISO)
The following are predefined application notes.
Query Requirement
Standard Reference
ISO 16792:2015, 5.1.1(a)
Note Text
ALL UNSPECIFIED DIMENSIONS SHALL BE OBTAINED DIRECTLY FROM THE CAD MODEL
Variable Name
None
Variable Type
Not applicable
Display Status
Optional
Comments
This note should be included for model-based designs (but is not required on drawings).
Model Precision
Standard Reference
ISO 16792:2015, 6.2
Note Text
QUERIED DIMENSIONS SHALL BE RESOLVED TO $PRECISION DECIMAL PLACES
Variable Name
Precision
Variable Type
Integer
Display Status
Optional
Comments
According to ISO 16792:2015, clause 6.2, 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.
Model Condition
Standard Reference
ISO 16792:2015, 6.1
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.
General Profile
Standard Reference
ISO 16792:2015, 8.2
Note Text
UNLESS OTHERWISE SPECIFIED, ALL SURFACES $TOLERANCE
Variable Name
TOLERANCE
Variable Type
Real Number
Display Status
Optional
Comments
Surface Profile 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.
Part Draft Angle
Standard Reference
None
Note Text
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'.
Sheet Metal Thickness
Standard Reference
None
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.
Non-rigid Part
Standard Reference
ISO 10579:2010
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.
