Please reopen this thread from 2013, it was marked as SOLVED. As of 2021, 8 years later, there has not been made one single improvement in working with assiciative floor plans.
The automatic generation of complete associative floor plans in form of a hidden line section including all necessary symbols (stair arrow, door opening symbols...) from the underlying 3d model is the most important feature of any cad system.
Actually ALLPLAN is lacking this most basic of all functions.

A serious functionality lack should not be marked as solved only because developement has no interest in solving the problem. (Numerous threads complaining about this issue can be found at german forums, all lacking a serious response from the dev-repartment)
