13. OPTIMIZATION

CHAPTER 13 'OPTIMISATION' 12 By pressing the "OK" button the selected cross-section or cross-sections are inserted in the "Groups" field. The other way to select the cross-sections is by pressing the "Pick-Select" button and then selecting a physical cross-section of a pole with the mouse. Then this cross-section is also entered in the "Groups" field. ATTENTION! The option here applies only to physical cross-sections of poles, therefore the display of physical cross-sections must be activated in the 3D model By selecting the corresponding group, the dimensions of the cross-section are displayed in the "Dimensions" field according to the graph. More specifically, the first column contains the initial dimensions, the second the minimum dimension limit, the third the maximum dimension limit, and the fourth the step of variation. The "Lock" column locks the dimension in order for it to remain unchanged at its original value. By pressing the "Lock" button all dimensions are checked, i.e. the whole cross-section is locked. The default values in the boundary and Step columns are those defined in the General Design Parameters and which all elements initially obey. By using the "Delete All" button, all the cross sections that have been defined are deleted, while by using the "Delete" button, the selected cross section is deleted. Using the "Initialize" button, the original limits are restored to the dimensions of the cross-section. Finally, by selecting the "Show" button, the elements that have the specific cross-section are displayed in red.
