To Specify the Geometric Tolerance Type
Click Annotate > Geometric Tolerance. The Geometric Tolerance ribbon tab opens.
In the Symbol group, click the Geometric Characteristic list. It displays the GTOL symbols available for selection. When you click any of type from the list, the type is applied to the geometric tolerance in the graphics window.
The following table shows the types of tolerances available and the appropriate types of entities that you can reference. Creo Parametric guides you in building a GTOL by limiting your choices to those that make sense in the context of the information already provided. The system also does error checking to help you avoid mistakes in selecting entities and datums.
Start by selecting a tolerance type; then select the reference entity, specify tolerance values, and so on. When you have fully defined the GTOL and placed it, the system informs you that the GTOL is complete.
