# Create Member Timeline
When considering the construction stages of a model, particularly when creep and shrinkage are a concern it is useful to be able to assign a timeline to a member or set of members. This is not used directly by GSA at present.
# Definition
Members
Select the list of members to be updated. Any existing timeline for these members will be overwritten.
Timeline
The timeline specifies when the seleced members are created, and for concrete members when they start drying and age at which they are loaded.
