Creating a SubStructure

The square plate model (consisting of 4 Points, 4 Lines, and 2 Surface Triangles) can be defined as a SubStructure.

NOTE:  SubStructures only reference drawing Objects. Objects referenced by SubStructures still exist as unique Objects in the Structure file. Multiple SubStructures can reference the same Objects.

• Choose Points in the Edit | Current Objects List to display the Points spreadsheet

• Execute Edit | Select Objects | Select All to select all Points

• Execute Draw | SubStructures | Add Objects to SubStructure

• Press the New SubStructure button in the dialog box that opens, and click on OK to create a new SubStructure

• The selected Points, (plus the Lines & Surfaces that reference the Points), are now referenced by the new SubStructure

• Notice also that SubStructures is chosen from the Edit | Current Objects List, and that the SubStructure spreadsheet contains the new SubStructure.
