Dimension text attributes
With Creo Elements/Direct Annotation you can add details to dimension text to further clarify your drawings.
What is a prefix?
Use a prefix to include additional information before the dimension value. Examples of prefixes are: DIA (diameter), TRUE R (true radius), and R (radius).
What is a dimension value?
A dimension value is the numerical value assigned to the geometry feature you are dimensioning. The value can be imperial, metric or angular depending on the geometry feature and the standard units you use.
What is a tolerance?
A tolerance is used to include information about the tolerance allowed in the dimension value. Tolerance is the total amount by which a specific dimension is permitted to vary. Types of tolerances are:
Basic Tolerances
Limit tolerances
Plus and minus tolerances
Upper and lower tolerances
Basic tolerances
Basic tolerances specify zero tolerance.
Limit tolerances
Limit tolerances are used to give the maximum and the minimum dimension values. The high limit (maximum value) is placed over the low limit (minimum value).
Plus and minus tolerances
Plus and minus tolerances are used to place the tolerance to the right of the dimension value.
Upper and lower tolerances
Upper and lower tolerances are used to place the tolerances to the right of the specific dimension value. They appear as upper and lower values of the permissible variation of the size of the feature.
The figure shows examples (from left to right) of limit tolerances, plus and minus tolerances, and upper and lower tolerances and basic tolerances.
The prefix, postfix, superfix and subfix texts can be multiline texts. The prefix and postfix texts of basic dimensions is single line.
What is a postfix?
Use a postfix to include additional information after the dimension value. Examples of postfix information are: 3-HOLES EQUALLY SPACED, and CONC (concentric).
What is superfix?
Superfix is additional information above the dimension value. Examples of superfix information are: 3- HOLES THRU and CONC.
What is subfix?
Subfix is additional information below the dimension value. Examples of subfix information are: 4- HOLES THRU EQUALLY SPACED and CONC.
