I have tried writing a dynamo script that filters out all the duct systems and selects all of the systems with the name SA (supply air). i then want to take this list and apply a value to a parameter called Uniclass_Systems_2015, but only for the systems containing SA. My script doesn’t seem to work and i was hoping someone could give me some advice?
try:
connect output of all ellements of category in to input list.filter boolmask
Ah yes Nico is right 
Also you could remove the list.create and the list.getitematindex node and just plug the ‘in’ port of the FilterByBoolMask straight into the setparameter node
i think list create is not unnecessary
you can remove that node i think
This time T_pover was faster:smiley:
thanks, i tried that out and it doesn’t error, however it also doesn’t push anything into the parameter in revit?
I think you need to plug the “all elements of category” directly to the first ListFilterByBookMask
It should work.
what kind of parameter storage type is uniclass… ?
is it realy a string or number or id?
so Uniclass_Systems_2015 is a project parameter we have set up and it will be populated by a code containing letters and numbers.
Hi Ahmad, thanks i tried your solution and it does work, however it applies the value to all the systems and i only want it to apply to one specific system type.
connect the nodes:
parameter.storagetype
in to
parameter.parameterbyname
in to
element set parameter by name
so you can check what kind of storage type the parameter is
are those nodes from a certain package or pre-built into dynamo?
pre built in
its a string
oke
youre input in element.SetparameterbyName is Right
you can try save and close dynamo and restart dynamo and run again
ok thanks, i’ll give it a go!
could you upload a new image?
you’re welcome
ps
mark this topic as solved
