Brackets are different from other symbols because they depend heavily on external topology (the structure to which they are bounded), and they need to cover a large variety of topological cases. Brackets fall into two functional categories:

  • Tripping Brackets - Created in the Molded Forms task. Tripping brackets derive the plane of the bracket automatically based on the supports. As a result, a tripping bracket must have at least one support that is an edge.

  • Detailing Brackets - Created in the Structural Detailing task. All supports can be faces, because the plane of the bracket is defined by an additional input.

The topological cases are generally covered by four bracket types. Within a given bracket type, any number of brackets can be developed.

The four bracket type categories are defined by the bracket topology and thus the bracket input geometry. The types are:

  • 2 supports (2S)

  • 3 supports (3S)

  • 4 supports (4S)

  • 5 supports (5S)

Supports refer to the graphical inputs the symbol requires from the software. The number of inputs equals the number of supports. Supports help locate the bracket in the 3D model space. The first two supports define the local U and V axes of the symbol. All supports may be used to bound portions of the bracket geometry, or to constrain the bracket without bounding it. Examples of the latter case are supports used on lapped brackets, or a support on the opposite side of the bracket.

Bracket supports must be numbered in the order that you pick the supports when placing a bracket in the model. Examples for each type are shown:

2S Bracket

3S Bracket

4S Bracket

5S Bracket

Example instructions for 2S bracket creation are provided. Other bracket types are similar.
