How can I extract the values that I can find after I have used the node Element.GetParameterValuebyName?

Hi everybody! I want to know the longer lenghts and the minor lenghts of every rooms of a house and I want to divide the major value with minor value for each rooms. So I selected the quotes of every roooms but I don’t know I can select the values that I want to do the divisions.dynamo%20problem3

Room.Boundaries might be a better way to start as it won’t require a dimension in every direction.

Once you have the curves, you can make a poly line and then a surface of each and the the X and Y distance aligned to the surfaces coordinate system which can be created a few different ways.

Sort the list by the built in sorting order, transpose the list, and divide the first item (shortest) in the resulting list by the last (longest).
