Bracket Plate System creates plate systems for primary structural brackets that can be stiffened, penetrated by stiffeners on the bounding structure, and split with design seams. Use the following best practices when working with the command. For more information, see Bracket Plate System.

Backside support

When a support is on the backside of another plate, select the edge of the support. Selecting the system results in an error.

The following example shows a bracket with the backside edge of a plate as one of the supports.

  1. Select the deck plate system as Support 1.

  2. The second support is a bulkhead on the backside of another bulkhead. Using QuickPick, select the edge of second support as Support 2. Do not select the plate system.

Length value and bracket parameters

When the supports are non-linear or non-planer, select a value for Length that is closest to or greater than bracket height and width parameters.

Ambiguity in a bracket support

When a bracket support has an ambiguity, select the correct side of the ambiguity.

The following example shows a bracket that is on the far side of the bulkhead.

  1. Select the bulkhead plate system as Support 1.

  2. Select the far side of the profile system as Support 2.

Bracket thickness

When modifying the secondary orientation of a lapped bracket profile support, also modify the bracket thickness direction so that the bracket is properly lapped.

In the following example, a lapped bracket is placed on a profile system, and the secondary orientation of the profile system is modified.

  1. Select the profile system you want to modify and click Properties .

  2. Select Section Orientation and modify Secondary Orientation as needed.

  3. Click Finish.

    The orientation of the profile system is modified.

  4. Check if the lapped bracket thickness direction is correct.

  5. If the lapped bracket thickness direction is incorrect, select the bracket and click Properties .

  6. Select Molded Conventions and modify the Thickness Direction as needed.

Molded Forms brackets versus Structural Detailing brackets

When a bracket must be penetrated, split, stiffened, or is needed for strength calculations (in an external analysis tool) or class drawings, use Bracket Plate System in Molded Forms instead of Place Bracket Parts in Structural Detailing.

Bracket symbols

Use a bracket symbol instead of a sketched bracket when a profile is a support and minimum height of the bracket nose is important. The nose height is not maintained on a sketched bracket when the profile height is modified.

Create multiple brackets using Auto Finish Mode

When you want to create multiple brackets with the same symbol and common supports, use Auto Finish Mode .

The following example shows a plate system with multiple two-support and three-support brackets created using Auto Finish Mode .

1 - Two-support bracket

2 - Three-support bracket

  1. For a two-support bracket, select the plate system as Support 1.

  2. Select Support 2 and click Auto Finish Mode to create two-support brackets each time you select a similar Support 2.

  3. For a three-support bracket, use Bracket Shape.

  4. Select the plate system as Support 1.

  5. Select similar Support 2 and Support 3 each time you want to create a three-support bracket.

1 - Support 2 for two-support bracket

2 - Support 2 for three-support bracket

3 - Support 3 for three-support bracket

Logical connection

When the bracket supports are not loaded in the workspace, you can identify the supports by the bracket logical connections in the Workspace Explorer.
