I have created 9 parametric families which each contain multpile mass objects with variable lengths.

I need to display the cut lengths and quantities required for the entire project in a schedule. So far i have only been able to display the total stud length required.

Is there a way of using a shared reporting parameter multiple times in the one family?

Alternativly can when scheduling can i combine multiple parameters into one column?

I have attached one of the families for reference.

Any suggestions would be appritiated.

In order to schedule sub components that are in a family, they need to be seperate shared families.

You can only use a parameter once in a family, although each nested shared family can have the same Length (or whatever) shared parameters. 

In Revit schedules, columns are created when you add parameters to the schedule, so each column corresponds to an inidividual parameter. You can't put more than one parameter in a column, but you can group parameter headings- for example, you might have Length, Width, and Height parameters, which can be grouped under a heading called Dimensions.

If you want to know how many 8', 10' and 12' studs you need, you will need to create a family with 8', 10' and 12' stud types and nest it into your stud panel family, and use them where needed. They will need an instance Length parameter if you want to get a cut list. But you can't cut Revit studs into several pieces as you could in the real world, so you may end up using an entire new 8' Revit stud for each small cut that you need. I think you'll need to export your schedule and do some math to figure out how many quantities of each length you'll need.

Thanks for the suggestions and quick responses.

I think I will go for the export to excel option.

It obviously would have been nice to get it working all live. but I am worried using separate nested families would over complicate the family (I haven’t used nested families much). I would be happy to do this however would it require the end user to fill in more parameters each time a family type is added in the project? Or is it possible to have nested families answer to the same parameters I already have compiled?

Thanks for your help.

Not sure what you are asking in your last question.  Nested families are controlled by the host family so editable parameters are passed through it.

I must be doing something wrong I will persist with the nested families and do some research. I have not been able to get the nested families to adjust from the original family yet

is it posible the length parameter of the nested families could conflict with the main family parameters?

"...is it posible the length parameter of the nested families could conflict with the main family parameters?..."

Only if you use a length parameter in the host to control the family.  A parameter called sublength (or whatever) could contol a nested family's length parameter.....It is just a "variable" name so don't use the same parameter as what is required in the host, unless it is the same.
