Colour schemes

[Alien]

These colour schemes are the category “Rooms”

But I don’t seem to be able to find that parameter in Dynamo:

Can’t do this either…

Basically I’m trying to filter by “Rooms”.

@Alien

the issue is you are looking for KeySchedule.Parameters

#📦 Variables
p_key_name   = 'Room Style' # Write Your Key-Param Name!
key_schedule = None

#1️⃣ Get all Schedules
all_schedules = FilteredElementCollector(doc)\
                .OfCategory(BuiltInCategory.OST_Schedules)\
                .ToElements()

#2️⃣ Get Key-Schedule            
for schedule in all_schedules:
    try:
        if schedule.KeyScheduleParameterName == p_key_name:
            key_schedule = schedule
            break
    except: 
        pass

#💡 Ensure you found matching schedule
if not key_schedule:
    forms.alert("Can't find matching Schedule.\nPlease Try Again.",
                                                    exitscript=True)
    
#3️⃣ Get Possible Key-Parameter Values
key_values = FilteredElementCollector(doc, key_schedule.Id).ToElements()
dict_key_values = {key.Name : key.Id for key in key_values}

#👀 Display Key-Parameter Values {Names: Id}
print('Key Parameter: {}'.format(p_key_name))
print('Matching Schedule: {}'.format(key_schedule.Name))
for k,v in dict_key_values.items():
    print(k,v)

this is a pyRevit Script. I think you can modify it. KeyScheduleParameterName Property

No luck. I can’t extract that

I tried with the set and with the individual items in the set:

i was too courious!
it works look

#2️⃣ Get Key-Schedule

[Alien]

That’s schedules not colour fill schemes?

[Draxl_Andreas]

@Alien

ok, i thought you wanted to get the related parameter. I think this schemes are not exposed to the Revit API…

[jacob.small]

It’s there as of 2022 I believe.

ColorFillScheme Methods

[Alien]

I did look at that… And I tried, “Cateogry” but no joy.
Even though category is listed in properties.

ColorFillScheme Properties

I have filtered by name atm as we’re using Room Name schemes… but I’d like to be able to filter by the main category.

[Nick_Boyts]

The Category property will always represent the element’s own category.
In this case, you want the CategoryId.

[Alban_de_Chasteigner]

Hi,

For information, there are several nodes in the Genius Loci package for color schemes.
But it will be less fun than digging into the API.

[Alien]

That’s a bit hard work innit!

Weird how I can’s just search for category name of the colour fill!

[Alien]

I am using some

But I wanted to do something specific with the other bit that I don’t think your package does?

EDIT:
OMG… I just saw… it DOES!!!

Oh dear… All that work. sighs
Well, at least I’ve learned something.

Well you kinda can. Remember, it’s an element parameter, so the value is an element/id. We can always get the category name from the category itself.
