Hi，I’m a new learner ，form China
And the question is “How to Combine multiple floors（same level） into a single”
I’ve searched in the forum or other place many times，but there is no right way.
it is easy to Decompose the floor（which Composed of several blocks） into many blocks：once get the outline of the floor，we can use the node “Floor.ByOutlineTypeAndLevel” to rebuild new Separate floors。
But how to reverse operation by Dynamo?
