I am using Rhino 5.
I was able to properly assign the Location and Materials and to run Radiation Map and Visualization...
Then I assign the Nodes by selecting the Plane of the floor that I have created in Rhino by using the command "Plane" and by accepting the default values for the height and distance of the Nodes... But when I try to run the Climate-Based simulation, I receive the error: "No nodes have been assigned to this simulation. Please set them with the Nodes button".
I tried several times and I even tried to turn off some of the existing layers, in my perspective view... but still the Nodes cannot be assigned.... I was wondering if this is a problem that someone else had wt Rhino 5.
