The Layout > Joists > Assign Size command in RAM Modeler is used to assign sizes to steel joists.

When that command is invoked, a list of steel joist sizes is listed. The list can show either Standard Joists (e.g., K - Series) or Constant Shear Joists (e.g., KCS - Series). Select the Type of joist desired by selecting Standard or Constant Shear. The displayed list can come from either the Default table or the Alternate table. The tables associated with these are specified in Criteria > Design Steel Tables in RAM Manager and can be modified in the Criteria > Joists command in the RAM Steel Beam module. Select the Table by selecting Default or Alternate. Select the desired size, and assign it to the joist or joists using either the Single or Fence command.

The Layout > Joists > Clear Size command in RAM Modeler and the Process > Clear Sizes command in the RAM Steel Beam module can be used to clear the user-assigned sizes.

The Options > Show Sizes command can be used to display the assigned sizes.
