I am attempting to make a family for an angled wall to enable the use of curtain wall at a slope.  Am attempting to follow a blog from waterman.blogspot.com.au. I have created a metric profile and dimensioned a line and set a parameter a type.  I have then made a generic wall based model into which I have loaded the profile.  I have made a parameter in the host family with the same name as that in the 'child', but as an instance with 'reportable' ticked.  Both are of 'length', stored under 'dimensions'; their attributes appear to be correct.

When I attempt to associate them I receive the msg: 

A reporting parameter can be associated to Element property only if its dimension references Are all to host elements in the family.

and no association can occur. 

I don't understand the error msg and would appreciate assistance.

I think you have it backwards.... The host parameter controls the child - not the other way around.   Can a parameter pass from the child to the host?   I have never checked but all parameters that are passed have to be type based parameters anyway.
