A bracket system can have a plane that is in line with one of its selected supports. This type of bracket is created when Plane by Selected Supports is selected for Select Plane. You can select a bracket symbol or sketch the free edge of the bracket. You can create two-support (2S) and three-support (3S).brackets.

The supports are used to define the plane of the bracket as well as its boundaries. The first two supports must intersect in a manner that allows the plane to be defined. Bracket orientation is driven by the orientation of one of the supports, such as a plate system or the web of a profile system.

The default bracket orientation is parallel to the first selected support having a plane usable to drive the orientation.

A flange can be added to the free edge of the bracket.

A bracket can be supported on the flange side of one or more profiles. It is created in the same way as other brackets except that the plane of the bracket is usually offset so that it can be fillet welded to the supporting profile flange.

A bracket by supports can be lapped to one or more supports.

A bracket by supports can use two intersecting profiles on the same plate as supports. The bracket can be supported by the web, or both the web and profile of the second profile.

A bracket is classified by its number of supports. The support object type selected affects the available support object types available for succeeding supports. The following examples show the general support selection sequence and the available combinations of supports:

2 Support (2S) Bracket

Support Order when Supports are Unconnected

Bracket supports are usually connected to each other, either by bounding or intersecting. There are some circumstances where supports are not connected. The supports must be linear (for profiles) and planar (for plates) so that the intersection of the unbounded landing curves and/or unbounded definition planes are unique.
