Draw Plan

plan_2d = Cluster.ByTopologies(
    Wire.ByVertices([Vertex.ByCoordinates(*list(x) + [z0]) for x in hall_plan]),
    Wire.ByVertices([Vertex.ByCoordinates(*list(x) + [z0]) for x in stairs_plan]),
    Wire.ByVertices([Vertex.ByCoordinates(*list(x) + [z0]) for x in kitchen_plan]),
    Wire.ByVertices([Vertex.ByCoordinates(*list(x) + [z0]) for x in frontLR_plan]),
    Wire.ByVertices([Vertex.ByCoordinates(*list(x) + [z0]) for x in backLR_plan]),
)
Topology.Show(plan_2d)

Draw 3D Cells

def cell_from_plan(plan, z0, z1):
    return Cell.ByWires([
        Wire.ByVertices([Vertex.ByCoordinates(*list(x) + [z0]) for x in plan]),
        Wire.ByVertices([Vertex.ByCoordinates(*list(x) + [z1]) for x in plan]),
    ])

    
hall = cell_from_plan(hall_plan, z0, z1)
stairs = cell_from_plan(stairs_plan, z0, z2)
kitchen = cell_from_plan(kitchen_plan, z0, z1)
frontLR = cell_from_plan(frontLR_plan, z0, z1)
backLR = cell_from_plan(backLR_plan, z0, z1)
plan = Cluster.ByTopologies(stairs, hall, kitchen, frontLR, backLR)
Topology.Show(plan)

Add windows

… I think I’ve approached this wrong… the walls must be made up of walls and windows…
