#### 2.1.2.4. Sublaminates

A sublaminate is a sequence of plies defined by fabrics and stackups with relative angles. This sublaminate can be used later in the lay-up definition. As with stackups, the sequence direction and symmetry can be chosen. Refer to Symmetries for more information. Sublaminates can be exported to an ESAComp XML file format and are converted to laminates in the process.

The Analysis tab is exactly the same as for a stackup. Refer to Analysis for information on the content of this tab.

Important: If stackups and symmetry are used in the sublaminate definition, the stackup is be reversed in the ply sequence. For example, for a stackup S1 defined as [45,-45,0], and a sub-laminate defined with even symmetry and the stackup ([S1]s), the sub-laminate sequence is [45,-45,0,45,-45,0], not [45,-45,0,0,-45,45].
