✱ Creating Revit Toposurfaces from Civil Survey Drawings - A Definitive Guide

Have you ever wondered if you can create a 3d topography model from the CAD survey data you have? Watch this video and you’ll see that we can use just about anything as long as it has proper height parameters.

I cover most of the scenarios encountered when you get a survey file from a civil engineer, which could be just about anything! We start with three different survey files in AutoCAD and distill the data down to just what we need, and then take it into Revit to make our 3d model using its Toposurface tools.

✱ Terrain Part Deux: Taking Your Terrain Model from Bonzai3d to Revit & More

Continuing from our last session where we made a terrain model in Bonzai3d from Google Earth and SketchUp, we take the next step by learning how to export varying densities of meshes out to Revit to create a parametric Toposurface. Then we start talking about additional Toposurface tools available to create and manipulate terrain as well as create a schedule that shows us how much cut and fill we moved around.

Topics I cover in Revit include creating the Toposurface from Imported Instance, adjusting contour distance, adjusting contour display, Split Surface, and how to set up a Cut & Fill Schedule after doing a Graded Region.
