I recently started a new project file at the office, and looking back over the archives, I figured it was a good time to revisit some of my workflows for file set up. At some point since I last posted about establishing coordinates, I discovered on Revit OpEd that you can actually acquire coordinates from a dwg file. Acquiring coordinates is by far the superior method for establishing coordinates. Not only is it more efficient but it is also more accurate and leaves less room for human error.
Steve’s post goes into some good detail about how to clean up your dwg file and also how you can link subsequent CAD files via Shared Coordinates once you establish coordinates. So I would definitely recommend reading his post, but if you are unfamiliar with either the Survey Point or Shared Coordinates, here is the step by step process. Continue reading →
If you have to model an existing landscape in Revit, Dynamo can be an excellent tool to automate that process. Not only can you quickly create existing hardscape (that follows Topo), but you can also automatically place and size existing trees using survey data.
In fact, you can use this process to automatically place any element that exists in your AutoCAD survey as a block.

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 →
While testing out some Civil 3D CAD links last week, I noticed another strange thing that was happening with some of the links. When the CAD link was reloaded (either manually or by closing and reopening the Revit file), it would actually move within the Revit file. The two images below show where the link started and where it would move.
It seems to be unrelated to the Civil 3D “splitting” effect, since it also occurs with a standard AutoCAD file. Continue reading →
