Unitless Value Assignment Not Resolving After Manually Adding Units

Question

Hello,

I am having an issue resolving a "unitless value assignment for symbol 'D22' error. I am using Creo 7. The part is a helical sweep to create a spring. The pitch of the spring is defined using parameters. The pitch is a calculated value from the parameter "LENGTH" and "NUMBER_OF_TURNS". I have applied units in the parameters window to "LENGTH", but it has not resolved the error. Annotation 2024-08-15 090239.png Annotation 2024-08-15 090351.png

I have also tried defining the dimension directly in the relations window, but that also does not resolve the issue.

Any ideas as to why this might be?

Thank you,

John

Hi,

Following up, I think I have a work around for now. I commented out the relation for the pitch parameter and then went in to the parameters window and added the units. Upon going back to relations and then uncommenting the relation for pitch, it recomputed the value and maintained the units set in the parameters window. Hopefully, this will continue to work. Thanks for the help.
