Creating A Toposurface By Picking Points; Creating A Toposurface From Imported 3D Data - Autodesk 24000-000000-9860 - Revit Architecture - PC User Manual

Sample topographical surface defined by picking points in a site plan view

Creating a Toposurface by Picking Points

1 Open a 3D or site plan view.
2 Click Site menu
3 On the Toposurface tab of the Design Bar, click Point.
4 On the Options Bar, set a value for Elevation.
5 Next to the Elevation text box, select one of the following:
6 Click in the drawing area to place points. If needed, change the elevation on the Options Bar
7 To complete the surface, click Finish Surface.

Creating a Toposurface from Imported 3D Data

You can automatically generate a toposurface based on 3D contour data imported in DWG, DXF, or DGN
formats. Revit Architecture analyzes the 3D contour data and places a series of elevation points along the
contour lines.
You must import the 3D contour data before creating the surface. See
on page 1307.
NOTE When you import data with the Current View Only option selected, you cannot use the data to create a
toposurface.
To create a toposurface from imported 3D data:
1 Open a 3D view of the site plan.
2 Click Site menu

Toposurface, or on the Site tab of the Design Bar, click Toposurface.
Revit Architecture enters Sketch mode. The Design Bar displays the Toposurface tab.
This value determines the elevation of the point being placed. (The points and their elevations
are used to create the surface.)
Absolute Elevation: Points display at the specified elevation. You can place points anywhere
in the active drawing area.
Relative to Surface: Allows you to edit an existing toposurface by placing points on it at the
elevation you specify. To use this option effectively, you may want to work in a shaded 3D
view.
