First time creating schedules.
I have created a schedule to identify my light fixtures.
One thing I can't seem to get to populate is the light fixture lengths.
Not sure if its due to them being dynamic rather than set in the family properties.
My LN2 light fixtures come in numerous different length which are changed in the individual light property.
The parameter is set as a type parameter.
In the family create different types for each length then populate the parameter in each type.
The schedule simply displays the values which are in the family. If there is no entry in the family then there will be no entry in the schedule. If you change the value in the family it changes in the schedule, if you change the value in the schedule it will change the value in the family - they are interactive and inextricably linked.
I think you are maybe not understanding some basic concepts in Revit.
"that value in the properties box must be available somehow as it is in the field"
Your own screenshots show that there is no value in the field in either the schedule view or the family properties. If you enter a value in the family properties it WILL appear in the schedule - that's the whole point of having intelligent interactive schedules.
"My other concern is that I have 20 types across 7 floors with 200+ per floor.
I would need to select each fitting and reassign it which would take ages."
The parameter, as shown by your screenshot, is a TYPE parameter so one value applies to every instance of that type.
You need to edit your family to create the 20 types. Or you can have 20 different families. Whichever suits your workflow.
Once you re-load the types into your project every fixture of that type will get the same parameter value so you don't need to alter the value for each individual fixture (in fact you will get a warning that you are about to change a value which affects all elements of that type).
You can also use the schedule to efficiently alter batches of fittings - sort the schedule by one of the parameters and disable the "Itemise every instance" box, select a line in the schedule and then change all of the selected fixtures at once.
You can also, in the family, tie your Shared Parameter value to the Family parameter value which controls the geometry of the extrusion, using a formula:
Note in the above screenshots that changing the type changes the length value uniquely for that TYPE.
Really appreciate the help with this and the detailed replies.
I think it may be to do with the family and how it sets the Length. I didn't set it up.
The length is drag able rather than being fixed.
I have gone into the family and locked the length to each variable size. as per your last screenshot.
I'm still going to have to change each fitting individually but once its done its done.
Just wish there was a way to select all LN2 with a Light Length of 2606 to then be able to change them to LN2 - 2606
Well that's weird because Family parameters don't appear in schedules.
I did earlier question whether the families which you uploaded were the same families as you originally posted about because in your original post the parameter was Shared and Type whilst the uploaded families had Family and Instance.
This is the fixture which you uploaded and as you can see there is no Light Length field available because the parameter in the family is a Family parameter
Just Curious... this may have been mentioned earlier but I missed it. but it not....
If you go to the Sorting and Grouping tab and Check the itemize every instance, assuming you're sorting by Type, does the Light Length populate for all the lights? I know this isn't what you're looking to do, but you mentioned earlier that the parameter was blank because their different sizes. I'm just verifying they are all filled in and the parameter does display if sorted "properly" (I'm assuming it will 😊).
