Hello,

Which configuration in cfg.xml file controls “Crack width load combinations”?

In examples in API docs only attribute for second order effect is shown, but not for other settings.

`<CONFIG s2ndOrder=“0” type=“ECRCCONFIG”>`

I have found solution in the documentation:

```auto
using (var conn = new FemDesignConnection())

{
var concreteDesignConfig = new ConcreteDesignConfig(ConcreteDesignConfig.CalculationMethod.NominalCurvature, true, true, false, false, false);

conn.SetConfig(concreteDesignConfig);
…
}

```

Correct 🙂

We have implemented the most important config options into a proper object class. I am glad you have found it!
