You can pattern and mirror structure system members using the
Linear Pattern, Circular Pattern, or
Mirror tools.
In the
Pattern
PropertyManager, under Bodies, you can specify
structure system features or individual members to pattern. You can also mirror members
by specifying structure system features or individual members under Bodies to Mirror in the Mirror PropertyManager.
You can add secondary members as a separate structure system feature between
patterned and mirrored members.
You can also create secondary members as part of a new structure system by
selecting members from existing structure system features.
