In this lesson you create a Toposurface by importing contoured data from a dwg file and using it to create the Project Toposurface. You add a Section Box to the 3D View of the Toposurface to cut the site and view the topography more clearly. Click the Menu Browser and select New, Project. In the New Project dialog click OK. Next we'll take a look at how to import contour data to create a Toposurface. Click the Insert tab and from the Import Panel click Import CAD, then in the Import CAD Format's dialog in the left pane click Training Files and select Common, Site Plan.dwg, and for Colors select Preserve. Make sure that the Current view only checkbox is cleared. You cannot use a drafting item to create a Toposurface. If you select the Current view only option when importing the dwg then the drawing is added as a drafting item and is view-specific. Click Open. Right-click and select Zoom to Fit. The Elevation Markers in the Project Template point to the origin. The drawing needs to be moved to the right to ensure that the building is modeled close to the origin of the Project. In the Drawing Area select the imported Site Plan. On the Modify Site Plan tab from the Modify Panel select Move. Then, click near the center of the building to enter the Move Start Point, then click to the right outside of the building to enter the Move Endpoint. Then click outside of the imported drawing, or press Escape to deselect it. Next, click the View tab and from the Create Panel click the 3D View drop-down and select Default 3D. Then click the Massing and Site tab and from the Model Site Panel click Toposurface. Then when the Edit Surface tab displays from the Tools Panel click the Create from Import drop-down and click Select Import Instance. Then in the Drawing Area select the Site Plan. In the Add Points from Selected Layers dialog click Check None and then select C-TOPO MAJR and C-TOPO-MINR and click OK. Then on the Edit Surface tab from the Surface Panel select Finish Surface. Next, to turn off the visibility of the dwg, in the Project Browser expand 3D Views, right-click 3D, and click Properties. In the Instance Properties dialog for Visibility-Graphics Overrides click Edit. Then click on the Imported Categories tab and under Visibility clear Site Plan.dwg and click OK. Back in the Instance Properties dialog under Extents select Selection Box and click OK. Next, let's look at how to create a Section Edge. In the Drawing Area select the Section Box then drag the controls to just the edges of the Section Box to cut the Toposurface with the box. Exact placement is not important. When the Section Box edge cuts the Toposurface the cut pattern is displayed on the edge of the Toposurface making it easier to see the topography. Now, to view the Toposurface right-click the Section Box and click Hide in view, Elements. Then, on the View Control Bar click Model Graphics Style and select Shading with Edges, then use the View Cube to view it from various angles. Then, close the file without saving it as that concludes this lesson.
