Dynamo is not recognizing the height or width parameter? There are multiple different door types in the model and we are trying to get all the heights and widths to help us create quick door elevations but due to the difference in types they have different parameters. The only parameters which we can use that are consistent are the “Height” & “Width” parameters yet they do not seem to be picked up by dynamo.

In the future, please try searching for similar questions before posting. This question has been asked and answered many times already.

Width and Height are `TypeParameters` which means they exist in the `FamilyType`, not the `FamilyInstance`. You need to get the `FamilyTypes` of each door first.

@neil.mackennon , use archilab package Get Type Parameter

Hi Draxl\_Andreas

I tried that already but the value comes back null.  
I have looked at lots of other examples of people having similar issues but height always seems to appear yet it does not seems to be working for me

Thanks

@neil.mackennon , @Nick_Boyts

I slowly understand this lenguage that noone can speak 🙂

```auto
import clr
clr.AddReference('RevitServices')
from RevitServices.Persistence import DocumentManager

clr.AddReference('RevitAPI')
from Autodesk.Revit.DB import *

doc = DocumentManager.Instance.CurrentDBDocument

def familyInstance(x,list):
	if isinstance(x,list):
		return x
	else:
		return [x]

elements = UnwrapElement(IN[0])
vals = []

for i in familyInstance(elements,list):
    # Get ElementId of ElementType
    tipo_id = elements.GetTypeId()
    # Get actual Element from Document
    tipo = doc.GetElement(tipo_id)
    if tipo:
        i = tipo.LookupParameter(IN[1])
        if i:
            param = i.AsDouble()
            metricvals = UnitUtils.ConvertFromInternalUnits(param,UnitTypeId.Meters)
            vals.append(metricvals)
    else:
        vals.append()

OUT = vals

```

@neil.mackennon , if it works you can mark it as solution… … so noone will ask anymore about calling typeparameters 😉

Thanks everyone, and I’ve seen I have annoyed some people with my question sorry. I then had to try to make it work with linked files doors but with a couple of packages and your advice I got it working. so thank you!
