2. MODELING

CHAPTER 2 "MODELLING" 43 EXAMPLE: For example, if you want to modify the thickness of the "PLEGMA 3D" mesh from 50 to 60 cm, first select the grid and then type the new value in the corresponding field. You then press and the grid now has the new value its thickness. A similar procedure is used to change any other geometric or physical attribute of the mesh. • "Steel Armouring and Coating": is the field where you select the quality of steel with which to reinforce your mesh. is the field where you select the thickness of the overlay. There is now also the possibility of defining the overlap by surface subgroup. • " Delete ": delete the grid or grids you have already created. From the "Grid Group Descriptions" section, select the grid and press the "Delete" button. OBSERVATION: The grid does not disappear from the list, but the word "Delete" is added to its name to indicate that it has been deleted. This fact allows you to restore a grid that you have already deleted by simply selecting it and pressing the "Delete" button. The word "Delete" from its name disappears and the grid becomes active again. To permanently delete a grid, after the "Delete" command, make a study entry via the OBSERVATION: Right-clicking inside the grid opens a list of commands related to the grid. The Delete Surface command allows you to delete both the mathematical model (if it exists) and its calculation, and the mesh itself from the list.
