The first step is to import a image file of the Smith House Site Plan into a cad file, which I've named Smith House Site Plan. I scale the image to the proper size. ( Fig 2).and rotate the image to True North, so that when I link the site file into Revit the site is at True North (Fig. 3)
With the lines joined I am going to assume that because the Smith House sits next to Long Island Sound that the first contour line is going to be at sea level. So starting with 0' I'm going to raise each contour line 1' until the last contour line which sits at 33'. (Fig. 5) is what the site looks like from the front view.
First, I change the name of Level One to Sea Level. Then opening up an elevation view and delete Level 2. After that I delete any view in the Properties Palette that I don't need in a site file such as the ceiling plans or an elevation. (Don't worry you can always create a new view if you need one.) Then I am going to save the file as a Template called Master Site Template.
Now we are almost ready to Link the file into Revit. I open the Site View and go to the Properties Palette. I change the Orientation to True North then scroll down to the View Range.
The Cut Plane is where the view will cut into geometry, which is typical at 4' in the floor plan views. The Site view it is set by default to 200' which is again fine for this particular project.
The Bottom Plane is the very lowest level of the view range. and is set by default to Level Below. then I click apply.
Import units: feet
Positioning: Auto Origin to Origin, In this case I will chose Origin to Origin. because I positioned the site in cad to 0,0
Place at: Sea Level
Note: Make sure you don't click the current view ( Which Is to the Left) because If you do, you wont be able to create a toposurface later on. Click OK and the cad file is linked into the Revit File.(Fig. 8) In part two I will link the Smith House Project file into the new site File and Publish the coordinates back to the project file.
