14 The Construction stages function helps to model and design the different building phases, and it helps to determine the construction process affected displacement/internal force distribution of the finished structure.
15
16 Construction stages can be defined in the Construction Stage [[image:1585148773332-671.png]] . Fill the table to generate custom construction stages, but it can be generated automatically with //Generate by Storeys//. Set the Initial state for every stage. If it is checked in calculation of the stage displacements will be reset, but other results will be kept.
17
18 There are two typical stage definitions:
19
20 1. High-rise buildings, where the stages comes from the storey system.
21 1. Arbitrary construction stage. In this case the whole structure will be assigned to the first stage.
22
23 After setting the stages in the Settings dialog the structural elements needs to reassigned to their respective construction stage – if it’s necessary.

28 There are also two options for **Auto-assigning by Storey:**
29
30 * newly created
31 * moved/modified elements

39 For every structural element the construction stage ID can be shown with Settings/Display/Bar/Construction Stage ID.
