When creating a new level in Concept Mode, you are now afforded the option of copying all the beams, columns, joists , walls and and loads from another level when creating a new level. Unlike Shearwalls, which can only extend the first level upwards, this feature allows for insertion of levels in between existing levels or as a ground floor level.
To ensure members are supported on the new level, the program can only insert adjacent levels, for example, it cannot copy level 1 and place it on level 3, as there is no guarantee the members on level 2 would properly support level 3. Two identical levels will always be supported if they are adjacent.
This feature revives and improves upon the copying of levels that existed in Version 1 of Sizer, but was thence dropped.
Operation
A checkbox reading Copy selected level when adding has been placed in the Floor and Roof Levels dialog, which is accessed via the Change Level button in the Concept mode toolbar.
If you click the Add button in the Floor and Roof Levels dialog with this checkbox selected, a level is added at a position defined by the value of the Elevation entered. It includes duplicates of all members and loads from the selected level.
Member names
The new members are named by the default naming mechanism as if they were entered by hand, that is, if the columns on floor 1 are c1, c2, c3 and c4, those on the copied level on floor 2 are c5, c6, c7 and c8.
Roof joists vs floor joists
The program does not attempt to convert roof joists to floor joists if a roof level is copied from below, or floor joists to roof joists if a level from below is copied to the roof. The best approach is to create a ground level, create a roof, and then copy the ground level to the intermediate levels.
Grid point elevations
Grid point elevations are not copied, so that a sloped beam on one level will become flat when copied to another level. However, there are few if any practical circumstances where one would want to copy sloped members or surfaces.
Live roof loads
A live roof load copied to a level below remains a live roof load and must be changed manually.
