Hi, This is my first post to the forum so hello all. I’ve been reading posts for some time and have found them very helpful. There are some very talented people here!
I’ve been looking at a graph to extract the properties from family parameters into an Excel file. I’ve used the nodes shown below
the FamilyDocument.Current & Family Document Parameters are from the Orchid package. The FamilyParameter.Properties is from the Clockwork package. Package versions are as shown below:
I’m running
The Orchid nodes work fine at extracting the parameters but when the data is fed into the Clockwork node I get null values for all properties. I’ve connected the list via a Flatten and have tried all three types of lacing but still get nulls.
I’ve also tried using the OOTB nodes to extract the parameters & taking 1 parameter from the list to connect to the Clockwork node.
Many thanks for your suggestion. I tried the GeniusLoci nodes and got the same result. All the nodes I’m trying work except the FamilyParameter.Properties node. I’ve also tried this in Revit 2021 and got the same result, nulls output from the #Clockwork node.
I’ve tried installing the latest version of DynamoIronPython but this did not solve my issue either…
Hi @manhgt214 thanks for the plugin link, I’ll give it a go if I cannot get the Clockwork node to work
Try pulling apart the Properties node to run it in your graph directly and see what fails there.
EDIT: It looks like all the parameters are failing at SpecTypeId (line 35). That’s leftover from 2021 but has now been depricated. You can replace it with the updated method:
Hi @Nick_Boyts Many thanks for the suggestion. I pulled apart the custom node as suggested then changed line 35 to your suggestion then ran the graph again.
I got a few errors on the custom node contents, the furthest upstream was on the first Python node:
Node Name: Python Script
Package: Core.Scripting
Dynamo Version: 2.16.1.2727
Host: Dynamo Revit
Messages: PythonEvaluator.Evaluate operation failed.
Traceback (most recent call last):
File “”, line 29, in
AttributeError: ‘FamilyParameter’ object has no attribute ‘Definition’
State: Warning
The line of code reads
pname.append(param.Definition.Name)
I only know the basic concepts of Python so have little idea of how to solve this, I tried deleting Definition in line 29, then got the same error on line 32. I’m guessing the Definition attribute needs to be replaced or removed but I’m not sure with what…
I was looking in the family section and didn’t see it and nothing was coming up when I used the search term ‘parameter’. I noticed the parameter section of the package and it’s in there.
Sorry for overlooking that. I read that, but then got lost in trying to figure out my stuff that I forgot about that. That solved the issue, thanks!
It’s still not exporting the info that is typed in for that parameter? There is the type parameter and it’s showing it’s a double, but not what is entered. Should I use another node to get that info? Similar to using a get name node?
