Hi!
To retrieve a shared parameter value called EZ_LINE NO for your list of elements (NK_CATEGORIES), you can use the Parameter property of an element to access its parameters and then get the value of your shared parameter. Since you’re dealing with shared parameters, you may need to use the GetParameter method with the parameter name as a string.
Here’s how you can iterate through your list of elements and try to retrieve the value of the EZ_LINE NO shared parameter for each element. Note that this code checks if the parameter exists for an element before trying to access its value to avoid errors:
# Function to get parameter value by name
def get_param_value_by_name(element, param_name):
# Attempt to get the parameter value
param = element.LookupParameter(param_name)
if param and param.HasValue:
# Check the storage type to ensure correct value retrieval
if param.StorageType == StorageType.String:
return param.AsString()
elif param.StorageType == StorageType.Integer:
return param.AsInteger()
elif param.StorageType == StorageType.Double:
# Optionally, format the Double value as needed
return param.AsDouble()
elif param.StorageType == StorageType.ElementId:
# Optionally, handle the ElementId type as needed
return param.AsElementId()
return None
# Parameter name to look for
param_name = "EZ_LINE NO"
# Iterate through each element in the NK_CATEGORIES list
for element in NK_CATEGORIES:
# Get the parameter value
param_value = get_param_value_by_name(element, param_name)
# Do something with the parameter value, e.g., print it
if param_value is not None:
print("Element ID: {0}, {1}: {2}".format(element.Id, param_name, param_value))
else:
print("Element ID: {0}, {1} not found".format(element.Id, param_name))
This script defines a function get_param_value_by_name that attempts to retrieve a parameter by its name and return its value depending on the parameter’s storage type. It then iterates through each element in your NK_CATEGORIES list, retrieves the value of the EZ_LINE NO parameter, and prints it out. Note that the print statements are just placeholders, and you should replace them with your own logic, such as storing these values or further processing them.
