[. . . ] Your cursor will change to , indicating that you are now in Draw a line through the truss web members, as shown below. Click your mouse to begin drawing the line near the leftmost truss web member, and drag past the rightmost web member, then release the mouse. 62 Tutorial 2 ­ Modify Notice the section set for all of your web members is listed as Chord. This is because you only had one Hot Rolled section set available to you when you first drew your truss. All of the truss web members should now be selected. You could now easily modify those selected members, as you will do in the next section. Modify Members In this section, you will use the Modify tools to rotate your columns. On the Drawing toolbar, click Draw New Members Select the Modify Properties tab. This dialog box looks similar to the Draw Members dialog box because, after the members are drawn, this dialog box allows you to change any of those initial parameters. At the top of the Member Material Type and Shape section, select the Use?. 63 Tutorial 2 ­ Modify The dialog box should now look like this: Note: You made your selections prior to opening this dialog box; however, you could have waited until this point to select the members. Just make sure, in either case, that your selections are made before you press Apply. Apply the changes and close the dialog box: Click Apply. Modify the section set for all of the selected members: On the Selection toolbar, click Select All On the Window toolbar, click Isometric Your model should now look like this: to select the entire model. to display an isometric view of the entire structure. 64 Tutorial 2 ­ Modify Model Rendering A powerful graphics tool in RISA-3D is the ability to display a rendered image of the model. A rendered image shows each member plotted using a true scale representation of the shape assigned to the member. A rendered view offers some important benefits: besides producing a very detailed image, it also allows you to easily review member orientations and member connectivity. There are also rendering options (within the Members tab of the Plot Options dialog box) that allow you to adjust pullback length and rendering transparency. Turn on the model rendering: On the Window toolbar, click Rendering . Copying Model Elements RISA-3D allows you to copy selected portions of the model. You will use this feature to turn your twodimensional model into a three-bay structure. On the Drawing toolbar, click Linear Offset Copy to open the Copy Selected Items dialog box. This feature is used to copy the currently selected portion of the model (in increments) in any or all three of the global directions. Notice there are several fields used to specify increments in the X, Y, and Z directions. Click Apply. 65 Tutorial 2 ­ Modify Because your entire frame was selected, all of the frames will be copied. Your structure should look like this: Next you will add a masonry wall panel to the back side of your structure. But before you draw the wall panel, delete the concrete columns from this side of the structure: On the Window toolbar, click Redraw to view the entire model.
