Feature Mapping roughness

Builder

Hi, 

 

I would like to MAP my roughness which I give the model with PMI's.

I am using the Teach Feature Mapping box in NX 10. 

 

But I dont know the functions or the definition.

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.
