Get the number of propagation existing on the model of blocks:
np = doc.countPropagation()
Get a propagation of the model of blocks:
propa = doc.getPropagation(index)
Find a propagation by an edge of the model of blocks:
propa = doc.findPropagation(edge)
Get all edges of the propagation and the way in the propagation:
edges = propa.getEdges()
bo = propa.getWay()
Set a law of discretization for a propagation:
propa.setLaw(law)
Get the law of the propagation for a propagation:
law = propa.getLaw()
Set the way where the law is applied on the propagation:
propa.setWay(bo)
GUI command: Discretize on the propagation edges
