There are essentially three different methods for creating Topography in Revit:
- Place Points manually
- Create from Important Instance (dwg)
- Create from Points Files (csv or txt)
When working with survey files, the first option obviously is not feasible and the third option usually has less than desirable results. Continue reading
In Revit, Toposurfaces are Mesh elements. By definition, a mesh contains points, edges, and faces. Topos are always more manageable to edit when they have fewer points and edges, but all of those edges can also make them appear unrealistic.
There are a variety of methods you can use to smooth out those edges, but one of the quickest ways to do this is to convert the Topo into a Nurbs Surfaces (in Dynamo, of course).
Have you ever wanted to get GIS mapping data into Revit? Well now you can with Elk for Dynamo, created by Timothy Logan at HKS. Elk was originally available only for Grasshopper, but now it is also available as a Dynamo package, which allows you to create Revit geometry from Terrain data and OSM files.
This is a must-have package for anyone who works in Revit at the urban design and planning scale.
If you’ve ever used Harry Mattison’s (Boost Your BIM) Revit add-in Topo From Lines, you might have noticed that it hasn’t been updated to either 2015 or 2016. But now you can do the same thing in Dynamo, and I have even created a custom node for this in the Landform package.
