Manage sub structures

Manage sub structures

Sub structures are saved user-defined selection groups of any objects which can be of any size and mix of object types, materials etc. They can be viewed in isolation and used as filters for many areas of program operation. Using sub structures has multiple productivity benefits throughout the Tekla Structural Designer workflow, from model organization and editing through to results review, design and output.

Note: In Tekla Structural Designer the term sub structure is specifically used to refer to a collection of elements, either above or below ground level. It is not being used to refer to that part of the structure below ground level (e.g. basements and foundations).

Sub structure characteristics

The basic characteristics of Tekla Structural Designer sub structures are:

  • Elements can be a part of more than one sub structure.

  • Not every element has to be in a sub structure.

  • Deleting a sub structure does not delete the elements within it.

  • Sub structures are distinct from, and should not be confused with sub models.

  • Sub structures themselves are never analyzed.

  • Sub structure groups are simply collections of other sub structures.
