Notice that as each station is displayed on the grid, its location in the plan and profile viewports is identified by a perpendicular line. Experiment with the zoom modes 1 Zoom in to the lane on the right-hand side of the assembly. Click Go To Next Station. Notice that the view zooms back out to the grid extents. There are three zoom modes in the view/edit corridor section tools. These modes control the behavior of the grid when you navigate to another station: ■ Zoom To Extents-View zooms out to the extents of the assembly, plus the view scale factor. This is the default zoom mode. ■ Zoom To An Offset And Elevation-View remains zoomed in on the current offset and elevation. As you navigate to other sections, the current offset and elevation remains at the center of the viewport. ■ Zoom To A Subassembly-View remains zoomed in on a selected subassembly. As you navigate to other sections, the selected subassembly remains at the center of the viewport. 2 In the Select A Station list, select 3+00.00. 3 On the View Tools panel, click Zoom To Subassembly. 4 In the Pick Subassembly dialog box, select Daylight (Right). Click OK. The view zooms in to the Daylight (Right) subassembly at station 3+00.00. Notice the shape, elevation, and offset of the subassembly. 5 In the Select A Station list, select 9+00.00. The view zooms in to the Daylight (Right) subassembly at station 9+00.00. Notice that the shape, elevation, and offset of the subassembly is quite different from station 3+00.00. The subassembly remains at the center of the grid and at the same zoom factor as you navigate to other stations. 6 On the View Tools panel, click Zoom To An Offset And Elevation. 7 Click Go To Next Station several times.
