EXAMPLE 2: 'DESIGN OF A METAL STRUCTURE' 63 The first step in dimensioning the layer is to define the dimensioning parameters. Because it is possible that for some of the layer members you may want to define different parameters, it is possible that within the same layer you can define different groups of parameters to which the layer members belong. The program has two default parameter groups. In the Configuration window, in the "Group Name" field is the name of the configuration group. If you want to create your own group, enter a new name and press the "Create New Group" button. For this example, select the parameters shown below: In this way the program will calculate as the buckling length ( bending buckling field - direction Y and Z) the length that has been given to the member geometrically (i.e. the length of the member from start node to end node). If instead you chose to set the bend length to an actual value you could enter a value in the "actual" field in meters. Then the programwould take as length what you would arbitrarily set -manual.
