Prepare a 3D DWG Contour File for Revit


In this video, we investigate how we should prepare a 3D DWG contour file so that we can easily create our typography within Revit. We notice how Southern hemisphere coordinate systems are sometimes mapped X to Y, and how it is possible for the coordinates to be increasing in a negative sense instead of a positive sense. Quite often the easting and northing are notated in meters while the actual eastings and northings are drawn in millimeters and similarly the elevations of the contours are also in millimeters.

Furthermore, the easting northings and elevations reflect the real-world distances from the origin. With the exception of a civil 3D surface must be linked in, the file can just be linked in using the center to center a setting in Revit.
