Whether you use Revit add-ins to help you manage data, batch process tasks, or automatically model elements, there is no doubt that Revit has an ecosystem of productivity tools built around it. Revit will even prompt you that the file must be saved to write the changes back to the Building file.įor a full list of Revit courses, click here.These days, there are typically several Revit add-ins in any power user’s toolbox. The Building file will now tolerate any number or relocations, by simply moving it from within the Site file. When the building file is reopened, views can be set to show either Project or True North orientation.Ĭoordinate values can now be reported in this file using either project or survey origins. Once the building is correctly located on the site, we use “Coordinates – Publish Coordinates” to write this new location into the Revit Building file. During my Revit training courses, I generally leave this (it will “inherit” the 20m elevation that was set at the beginning). The elevation (Z offset) of the building can also be set at this point, by selecting it in one of the predefined elevation views and adjusting up or down.

The Site file is reopened, and the Building file referenced in I generally use either the “Manual – Base Point” or “Manual – Center” positioning option, since the building is going to be correctly located on the site. Now the relationship between this point and the building will be agreed, and stated, in the BIM Execution plan it could be at specific grid intersection, or at a specified offset, but that is not the subject of this blog. Using the “Site” floor plan view, I simply draw two model lines across the base points, to indicate these when this file is referenced into the Site file. I start by creating a new Revit project file from the standard Architectural template. The Site file can now be saved and closed. The Project Base Point is selected and is relocated to the new location: The OS location is now set, using “Coordinates – Specify Coordinates at Point”.

The drawing is then moved so that the agreed site base point is coincident with the Revit base points. You may want to clear this option when importing/linking to site plans. Selected by default, this option automatically corrects lines that are slightly off-axis (less than 0.1 degree) and helps avoid problems with Revit elements generated from those lines. When quoting from the Revit 2019 help file:

The next step is to reference in the survey file I use a very simple dwg example drawing during my Revit courses, oriented to its OS location. The units obviously aren’t very important, they just make reading the coordinates a little easier. Since this is to be my site file, I also set the default units to display in metres. I use the Architectural template because it includes a “site” floorplan, showing the survey and project base points. Preparing the Site Fileĭuring my Revit courses I simply create a new project file from the standard Architectural template and name it to include the word “Site”, for obvious reasons. The main reason for keeping these separate is to accommodate any future repositioning of the building, but it also allows for the easy set-up of any additional Revit models required as the project progresses. The basic premise here is to keep at least two Revit project files one for the site and one for the building.
