Improved lift introduction

As of version 2023.d, when a lift is entered in the model (available in the “Connections” tool of the “Building elements” group in the “Architecture” tab), the program detects the floor slabs it crosses and will add an opening in them automatically. It also detects any walls next to the lift door and, in that case, it also adds an opening to them automatically.

It should be noted that, if the lift is deleted, the lift openings that have been created will remain in the model and must be manually deleted if they are no longer needed in the model.
