Precast member design groups
Why use precast design groups?
- For editing purposes - individual design groups can be selected and displayed graphically so that their properties can be changed as a group in the properties window.
- For design - to standardise designs, reduce processing time, and reduce the volume of output created.
A fixed set of rules are used to automatically determine member groups: for example beams must be of similar spans, columns must have the same number of stacks. Members in all member groups must be of similar lengths and cross-section.
Activating precast member design groups
Precast beam and column design groups are activated as follows:
- From the Design tab, click Settings> Design Groups
- Select concrete beams and/or concrete columns to activate precast beam and/or precast column design groups.
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.
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.
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.
