We will use the survey point to assist us in tying down the Revit model.

The survey coordinate system (Survey Point): provides a real-world context for the model.

The project coordinate system (Project base Point): provides local context for measuring distances and positioning objects in relation to the model.

The location of the internal origin never moves.įrom the internal coordinate system, you can establish the following: Note: The internal origin is also called the startup location. The internal origin is the starting point for the internal coordinate system, which provides the basis for positioning all elements in the model.

All geometry for the model, including geometry from an import or a link, should reside within the limits of the modeling work plane.” “When you create a Revit model, you are working on a modeling work plane that is 20 miles or 32 kilometers in diameter, with a radius of 10 miles or 16 kilometers from the internal origin. Revit, however, doesn’t come loaded with CS and has further limitations on what the size of your model can be, and the distance from the project origin. A CS must be set in order to use this functionality. Bing Maps is great to serve as a reference tool and has imagery that can easily be turned on and off.

Once a coordinate system is selected, you can do things such as turn on Bing Maps, reproject GIS data and images, and many other project related tasks. If you know your CS code, you can simply type it into the box. Setting the coordinate system in Civil 3D is very easy, simply right click on your drawing name from the Settings tab of your Toolspace.įrom the Units and Zone tab you can set your Category (State/Country) and well as choose from a list of available coordinate systems (CS). I thought I’d briefly explain how the coordinates of both Civil 3D and Revit work.Ĭivil 3D is preloaded with a huge library of coordinate systems and easy to create custom coordinate systems, or project coordinate systems in. I am 100% guilty when it comes to both of those statements! But there are some helpful ways to implement Revit to Civil 3D and/or Civil 3D to Revit workflows. And as an architect, sometimes working with the civil engineer’s JUNK is not worth the hassle.
