When I do a part model check, there are relation errors " Unitless value assignment for symbol"
How can this issue be resolved?
What version of Creo?
What check is issuing that error?
There are hundreds of settings in the check file and the start file that can be configured to check what you want.
when you search the error message you will find this article: https://www.ptc.com/en/support/article/cs216904
it's related wit h option relations_num_const_units and definition of your parameter.
