Chamfer dimesioning & tolerancing

[Atlas_8850]

As per the original post. 

Is there any way to use the existing model annotation and add a tolerance to its angle? Surely it should be this easy: https://www.youtube.com/watch?v=8fzz2cMiAZc

Using Angle x D chamfer, you can add a tolerance to the angle.

Can this tolerance be edited on the drawing (where all the other tolerances are usually edited)? Or are chamfer tolerances "trapped" in the .PRT file and can only be edited there? 

[StephenW]

As with all shown dimensions, you can edit the dimension value or tolerance value in the model or drawing using the ribbon or by double clicking the value.

Ah, my apologies, I should have clarified: is there any way to do this in a single dimension? E.g. a single leader line which points to the chamfer and says 0.030 x 45°? Can you add that kind of chamfer callout (like in the video I linked) and adjust its tolerances from the drawing?

[StephenW]

The notation for a 45° chamfer is a special case based on ASME Y14.5. It can only be used because "the linear value applies in either direction".

My interpretation of this based on ASME is the linear value would be measured in both directions and must meet tolerance for the linear dimension. The

Tolerancing the angle in this instance doesn't apply since you don't know what direction you are measuring from (horizontal or vertical surface).

Explicitly specifying the angle on the drawing as a separate dimension allows you to add a tolerance because you are explicit in showing what surface you are measuring from.

Creo does not create that specific dimension type.  You can create a note similar to it by placing the dimensions, setting the tolerance, and adding the dimensions to a leader note.  Once in the note, you will need to go to the model to modify tolerances.
