Ply groups

You can create logically linked ply groups in order to efficiently create and subsequently modify complex layups.

A group can be a child, a parent, or both. A newly created group is automatically a parent until the children are unlinked or it is deleted.

Child groups are linked to parent groups as follows:

• The child group plies cannot be directly deleted or modified.

• When parent group plies are deleted or modified, the same changes are applied to the child group plies.

• A ply cannot be added to a child group.

• When a ply is added to a parent group, it is automatically added to the child groups according to the link rules.

• If a child is both a parent and a child, it cannot be directly modified, any modification must be done to its parent.

Groups may not be nested.

To modify the contents of a child group without modifying the parent group, use the Unlink command to disconnect it from the parent group.

Group labels

Groups are labelled 1, 2, 3, and so on in order of creation.

Parent groups (1) are identified by a blue heading in the ply table.

Child groups (2,3) are identified in two ways:

1. Child group headings contain a description of their link rule in the Composition column of the ply table.

2. Child groups appear under a magenta heading in the ply table, and the plies within the group are shown in red.

Link rules

There are three types of links between a parent and a child group. These are based on which of the three Paste commands was used to create the child group:

1. Paste (2)

2. Paste symmetric

3. Paste anti-symmetric (3)
