To create a parking lot with Site Designer, add a toposurface to represent the parking lot surface, and add features, such as parking islands.
This video demonstrates the following:
Site Designer creates parking lot elements by making modifications to the existing toposurface and then placing a new toposurface on top to represent the parking lot surface material. After creating the main parking lot surface, you can create parking lot features, such as parking islands, by placing curb elements.
In this example, a parking lot is needed in the area defined by the perimeter curb.
Model lines representing the perimeter of the parking lot and the internal parking lot islands have already been added.
On the Site Designer tab, Locate panel, select Parking Lot. In the Locate Parking Lot dialog, select the family and type and give the parking lot a name. Select Use Existing Host Line to use the model lines already placed as the edges of the parking area.
To select the lines, click Insert. When you select one line of the perimeter, the other lines making up the chain are automatically selected. The underlying toposurface is altered to accommodate the parking lot and then the new toposurface is placed. In the Locate Parking Lot dialog, click Close to complete placement or add more parking lot areas, as required.
To add islands to the parking lot, use the Curb tool. Select the family and type, and name the curb. Select the option to use existing model lines as host lines. Click Insert. A site element will be added for the curb. When the Curb tool is used on a closed loop, the internal portion of the loop is filled with a toposurface up to the top of the curb.
Because of the behavior of toposurface elements, the island in the example has been broken into 3 loops to create the overall form. Select a line in one of the loops; the chain of lines is automatically selected. You must then associate the island with a toposurface. If the associated toposurface changes, the island updates accordingly.
In this example, we choose the south parking lot as the associated toposurface. Then we add more islands. Zoom in to see the results. The toposurfaces filling the islands inherited the material properties of their associated toposurfaces. Select the filling toposurface elements, and change them to match the surrounding site area.
