I'm trying to create a simple 8x2 extrusion that will represent an aluminum band on a building elevation. The length varies by instance but needs to be reportable in a schedule (preferably using the "Length" shared parameter name.
I've never used reporting parameters before but have made an attempt at it in the attached file. The parameter of Length displays the stretched length in the properties box but won't appear in a schedule. The Instance Length parameter will appear in a schedule but doesn't always show the correct value.
I'll note that this family was adapted from one already created by someone else and the Length label cannot be deleted. It's as if the file was at one time a template. However, I've tried it from scratch,t oo and can't get it to work, sometimes not even being able to get the family to allow stretching the length.
There's obviously a basic concept for this that I'm not grasping. Any help would be appreciated.
Solved! Go to Solution.
If you want to schedule the length value of a family in a project, you need to associate that length with a shared parameter (instance, length), in the family. Then, in the project, from the schedule, add the shared parameter to the schedule.
Late last night I found an article that suggested to me that what you offered might be the solution. I'll give it a try today. Thanks.
Sorry to bump a post from June, but I have a question about the procedure to associate "length" with a shared paramter.
Any links to how to do this, or could someone point me in the proper direction?
To associate the Shared Parameter to the Reporting Parameter, you only need to enter the exact name of the Reporting Parameter as the formula for the Shared Parameter. This will create a direct dependency to that value.
And bump-away! If the question is directly related to the thread, it's better to add to it than to start a new thread.
Still on the subject of a parameter for length...
In the OOTB Generic Line Based Family Template there is a 'Length' parameter. But it's a family parameter and therefore can't be scheduled. But because there is already a parameter called Length I can't add a proper shared parameter with the same name.
I could just ban the Generic Line Based Family Template and use another one instead, adding the reference line and shared parameter myself ... but that would be silly. What's the right way to fix this silly issue (especially now that our office has quite a few Lines Based Families from that template).
I would suggest not naming Shared Parameters with such names as "Length" or "Voltage" because Revit already uses a lot of the simple names like these. Name your Shared Parameters differently enough to reflect the difference, and then in the Schedule, you can rename the Field to anything you wish. As an example, ALL of the Shared Parameters that I create and include in my Families and Projects are prefixed with a "₪" symbol, for example "₪ Length" or "₪ Voltage". This acts as a clear designator to all that this is a Shared Parameter. This symbol does not appear anywhere in the finished project, as it is removed from the Field names in Schedules.
