[. . . ] This tool will help you quickly create all of your secondary members: On the Drawing toolbar, click Generate Beams . 35 Tutorial 2 ­ Modeling Beams Click once inside each open bay to fill in (as shown in the image below) until the upper left side of model looks like this: If you zoom out to view a larger portion of your model, you can generate secondary beams in multiple bays at once. Draw a box around the area between grid lines F5 and J10 to select the entire area. 36 Tutorial 2 ­ Modeling Beams When finished, your model should look similar to the one shown below: You can also use this tool to generate infill beams that are parallel to an adjacent member. Under Beam Orientation, click Angle to a Beam, then enter an angle of 0. First click on the bay you want to fill in and then click on the member that the new beams should be parallel to, as shown in the diagrams below. 1st Click 2nd Click 37 Tutorial 2 ­ Modeling Beams Continue with other bays until the radial portion of your model is similar to that shown below: Terminate the drawing tool using the right mouse button (rightclick) or press ESC. 38 Tutorial 2 ­ Modeling Beams Additional Beam Drawing Tips (optional) Before moving on, we recommend exploring some of the other beam modeling tools provided in RISAFloor. The steps in the remainder of this tutorial are optional, but you may find them very helpful to master. The first tool will demonstrate how to add ten members by simply clicking on two end points. On the Drawing toolbar, click the Draw or Modify Beams button again. Click the Draw Beams tab, make sure that the Keep spans continuous (as drawn) check box is NOT checked, then click Apply. Click at the start of the first beam (C2) and drag to the end of the last beam (C5). The single span beams will be automatically broken at the supports for you. Since these members should not be a part of your completed model, click the Undo button to undo the creation of the beams. Note: When drawing new members, you may create either single or continuous span members. If the Keep spans continuous check box had been selected, RISAFloor would have created a continuous beam that spanned from C2 to C5. 39 Tutorial 2 ­ Modeling Beams Another useful tool is the ability to offset beams from the end of another parallel beam: On the Drawing toolbar, click the Draw or Modify Beams button Draw Beams dialog box. to again open the Under Drawing Options, click Draw Beam to Beam. In both the 1st Offset and 2nd Offset boxes, enter 5 ft, and then click Apply. Experiment with this tool by clicking to create members parallel to the diagonal beam between D4 and C5, as shown in the image below. These offsets are automatically taken from the end of the beam that is closest to where you clicked.
