CHAPTER 2 "MODELLING" 15 • The button : offers a 3D representation of the beam, with the specific cross-section and angle, which you can modify by selecting a different angle by pressing the buttons with the angles. By pressing and holding the left key and moving the mouse, the plane rotates and you can see the beam around the perimeter ,. • The " R.Offsets " option enables or disables the existence of rigid sections in the beams. The option indicates the way of placing the beam, i.e. which passage will be chosen for its design. KEYBOARD COMMANDS: The positioning of the beam can also be adjusted via the keyboard. TAB to change the beginning and end of the beam SHIFT to change the beginning of the beam's passage CTRL to change the end of beam pass Select the cross-section of the beam and the insertion point (start) by left-clicking on the desktop. Before selecting the end point of the beam, press TAB, SHIFT, or CTRL, depending on how you want to position the beam. • With the " Inverted " option you indicate whether the beam to be placed is inverted. From the list of predefined layers you can select the layer to which the beam to be inserted will belong. The automatic default is the layer "Concrete Beams". • " Register - Select ": the user can create his own cross-section library, through the "Register" command, and call it at any time through the "Select" command, without having to define the same cross-sections each time. • " Info " (Details) : select to see all the geometric and inertial data of the specific cross-section.
