Dimensions that have general tolerances can be temporarily viewed with their tolerance values in the viewport. This "show" function can also be used to remove from display all dimensions other than those selected.
Note that the Show command has no effect on dimensions having different types of tolerances other than general.
To show general tolerances on selected dimensions,
1. Click 3D Documentation and then, in the Display group, click the arrow next to Show.
2. Click Show Default Tolerance. The Show General Tol dialog box opens.
3. Click a dimension having a general tolerance, or use the Select tool to select multiple dimensions. Creo Elements/Direct Modeling highlights the selected dimensions, showing their plus/minus tolerance values.
4. Click the Show only check box to display only the selected dimensions in the viewport. All other dimensions are hidden.
5. Click to complete the Show session.
You can de-select the current annotation selection by clicking Reset, allowing you to select new annos to show. To move between different general-toleranced dimensions in the viewport, click Next and Previous.
