Lenght parameter for generic model

[JEL_PLH]

Hi

I have created a generic model for facade drainage with a profile and a sweep. 

How do I ad a length parameter, so I can get a total length in a generic model schedule?

Thanks

Thank you. 

I've tried you solution, but I still cannot create a Generic model Schedule with Length as a field.

Make Length2 as Shared Parameter.
