[SasView Users] Model building in sasview

[Paul Butler via users]

Hi Harrison,

I cannot say that I've every tried that but note that the
documentation does suggest (or at least imply) it is possible. So I tried
and failed. I've forwarded your message to the developers mailing list.
Hopefully somebody will know the answer?

Cheers
Paul
