Workers Of Wood

Has anyone used this software before? Someone told me that it was good for designing intricate parts as I am trying to do on a replacement part for an antique wall clock to match the part that was broken. If you have used this before, is the learning curve steep? Does it have any advantage over Aspire? I saw on one of the Aspire videos that they designed something in Rhino and imported it into Aspire. Just curious.
