Lunchbox 2016.11.10 - Lunchbox Room Element Collector Issue

1

The Lunchbox Room Element Collector is not working on the Revit 2017.1 dynamo 1.20 but works on Revit 2016? Has anyone encounter this?

Hi @Emmanuel_Manago

Alternatively you can try @john_pierson “Rhythms” Package node “Room Element Collector” node.

Thanks Kulkul! I hope the package get updated soon. It is really a great package. I will use the “Rhythms” package for now (also a great package).

If you want to use the Lunchbox node, it just requires a change of one piece of code in line 82.

In the Revit 2017 API, the method changed from “BoundarySegment.Curve” to “BoundarySegment.GetCurve”.

I modified the script to figure out if the Revit version is 2016 or 2017 and use the correct method. Just past this in the python script.

Wow, thanks a lot John. It works now!

Hi Guys

I have a question. I want to know whether can we add the parameters that we defined for the rooms in Revit into “LunchBox Room Element Collector” node in Dynamo. I defined a shared parameter namely " Assignable" which is a yes/no parameter and assigned this parameter to each room in my Revit model. Now I want to put it in my “LunchBox Room Element Collector” node. In fact this node as you know has some predefined parameters such as Element, Name, Number, Area, Level Name, Location, Boundaries, Element ID, and Unique ID. and I cannot add any more parameters to these outputs if I want. Do you know how I can do that? Than you so much in advance.

Quickest way = use a get parameter value by name node on the elements

Replacing the script did the trick for me! Many thanks! :sunglasses:
