Tech assistance requiring AECOsim : Slicing levels from a merged model

We require an urgent tech support for a query in AECOsim as we are finding difficulties to segregate individual levels from the merged AECOsim model. We just need to segregate individual levels from the entire model consisting of 5 levels as shown in the snap.

Can somebody suggest a solution to the same so that we may output DWG/PDF of individual levels.
