I learned that you can create diameter dimensions in sketch mode by clicking back and forth between the symmetry line and the line that you want your dimension on for two times. However, in my case, it does not work, I get an error message:My sketchThe error message that I get.

Does somebody maybe know what is wrong, why this situation occured or what can be done about it to avoid it? Thanks for any replies!

Make sure you are selecting the centerline and not the reference.

Selection has to be centerline - geometry line - center line

-or-

geometry line - centerline - geometry line

you can't pick the geometry line twice and the pick the centerline or pick the centerline twice and then pick the geometry line.

What is your version and release of Creo?

It could be a release bug.

The mouse move has indeed to go back and forth between your first and second selections to be succesful like described in the documentation: https://support.ptc.com/help/creo/creo_pma/r9.0/usascii/#page/part_modeling/sketcher/To_Create_Diameter_Dimensions.html#
