Please explain what you are trying to do and why, based on attached flow chart.
NX recognize my feature, but i would like to create a feature process for my feature with a
critera for a roughness value. But first I want to Map my feature with a roughness rule.
I would like to find a type of a Feature with a Roughnessvalue of < 5 for example.
I tried it with the mapping-rule roughness_value(mwf.SIDE_ROUGHNESS_2_ROUGHNESS_VALUE < 5
but it still finds the all features. I set the one feature with an Rz of 0.6.
You can define the mapping rule like in attached picture.
You must use function roughness_value().
This is necessary since the roughness parameters are stored as strings.
In order to do calculations on roughness values, like saying it must be < 5, the numerical value must be extracted. That is why we need this function.
