13. OPTIMIZATION

CHAPTER 13 'OPTIMISATION' 19 Defining the elements of a group can be done either all at once the first time, or by adding elements to an existing group afterwards. You select the existing group from the list and use the "Pick-Select" command to select the elements you want to add. With the option when checked, all the poles of a column row can be automatically selected by graphically selecting any of them. This procedure allows only one element to be selected. For the dimensional domain apply the same as described above for the cross-section dialogue box. Finally, the following commands apply to all modules and apply to all sections: • The "Delete All" command deletes all groups that have already been entered. • The "Delete" command deletes the specific group you have selected. • The "Initialize" command restores the limits to their original values as specified in the General Parameters. • Finally, the "Show" command displays the selected group items in red. 2) For the " Beams " section, exactly the same applies as previously mentioned for the poles. 3) For the next two sections 2D and 3D Surface the following applies: The group or groups you create can consist of one or more surface elements. It is recalled that in the surface the only parameter that can be determined is the thickness. So you define a new group and with the graphical selection tools (individual, windowed, etc.) you select the surfaces that will make up the group you create.
