Automatic Grouping
Precast beams and columns are grouped automatically according to a fixed set of requirements.
In Model Settings > Grouping the user defined maximum length variation is used to control whether elements are sufficiently similar to be considered equivalent for grouping purposes.
Manual/Interactive Grouping
After assessing the design efficiency of each group, you are able to review design groups and make adjustments if required from the Groups tab of the Project Workspace.
See: Manage groups in the Project Workspace
Note: When manually adding members to a group, the order in which they are added will incrementally affect the average length within the group, (which is then compared to the maximum length variation). Therefore, if members are not being added as you expect, try adding them in a different order.
Regroup ALL Model Members
If you have made changes in Design Settings that affect grouping, you can update the groups accordingly from the Groups tab of the Project Workspace by clicking Re-group ALL Model Members.
Note: Any manually applied grouping will be lost if you elect to re-group!
