2. MODELING

CHAPTER 2 "MODELLING" 67 Also added the Change - Opposite button changes the local from +x to +y and vice versa, while the Rotate 90 command rotates the gyro homophore 90 degrees with each press. ❖ Every time you define a 3D surface grid, to automatically redefine the correct direction of the surface elements, you should ALWAYS select the " Automatically " command. To display the local axes of the surface elements, activate the corresponding option within the Switches . The arcs that appear define the local axes of the surface features, according to the clockwise screw rule. The direction of the arc indicates the x and the point at its edge, the direction. In the new version of the program, the local axes in the surface finite elements are now displayed in 3D for a better overview, following the well-known convention of the right-handed screw and in colours: Red axis (Red) : X Green axis (Green): Y Blue axis (Blue): Z
