Revit 2023: How to define the coordinate system in Revit such that the drwaing gets located in the correct place in ArcGIS Pro?

 

I couldn’t figure out how to define the coordinate system in Revit such that the drwaing gets located in the correct place in ArcGIS Pro

 

For example, I need to locate the marked edge of the building to be at the point (160000, 170000). How this could be performed?

Export the ArcGIS to DWG with geolocated. Next you link in the CAD into your Revit. Move the CAD to where you building will sit on. Then once you are satisfied with the CAD location, then you acquire coordinates and choose the CAD link. Revit will automatically adopt the coordinate from ArcGIS.

But how to manage all of this in the Revit side given that the coordinate of one of the corners of the building is given which is (X,Y) = (1600002, 170000) as marked in the screenshot below.

 

Is this point not sufficient to define the coordinates in the Revit?

Unclip the Survey Point and move it to the corner of the building you have known coordinates for. Then use Specify Coordinates at Point and select the Survey Point, enter the coordinates. Now Revit's Shared Coordinate system will allow you to export to DWG format using that points relationship to the WCS origin of a DWG file. Just make sure when you export from Revit is set to use Shared Coordinates system, not the Project.

 

When you xref the Revit exported DWG to another DWG file and place it's origin (WCS 0,0,0) at the origin of the hosting DWG file they should line up. If the building is rotated on site at all you'll need to know the angle to true north so it will align that way too.

 

What @syman2000 recommended can make the process a little easier because Acquire Coordinates will do all that for you after you position the DWG file relative to the building as required.

I followed the steps but as the Revit file is added to the ArcGIS Pro it’s not located in the correct place. It’s supposed to be at (160000, 170000) but it is as indicated as marked in the last screenshot

Because currently there is no relationship between ArcGis coordinates and your Revit model so these coordinates  mean nothing.  Do some reading.

How to make a relationship between the Revit coordinates and ArcGIS Pro?

If you cannot export ArcGIS to DWG, then use the AutoCAD and click on the set location

 

syman2000_0-1691004092116.png

 

Just add the Latitude and longitude location.

syman2000_1-1691004139166.png

Then go to the website and convert the Palestine Grid to UTM coordinate from the link

https://epsg.io/transform#s_srs=7142&t_srs=4326&x=160000.0000000&y=170000.0000000

syman2000_2-1691004217029.png

Enter in the latitude and longitude information into AutoCAD. Click on Drop the marker. If you know the elevation, enter it or keep it at elevation 0

 

syman2000_3-1691004286936.png

 

Next you would select the coordinate base on your local jurisdiction. Since I am from North America, we use UTM84-36. If you want to use the same Palestine Grid, then pick one of the options.

 

syman2000_6-1691004518580.png

 

AutoCAD will ask you to set the origin point and orientation, choose 0,0,0 and 90 for north

 

syman2000_7-1691004596379.png

 

AutoCAD will display map of the area. Sketch a simple object like circle and save the drawing.

 

syman2000_8-1691004634465.png

 

In Revit, you link the CAD

 

syman2000_9-1691004863586.png

Then you click on acquired coordinates and select the DWG link

 

syman2000_10-1691004950563.png

Revit will prompt you with this message

syman2000_12-1691005007527.png

Your Revit is now set to Palestine Grid

With the help of your useful screenshots and the dwg file you have already attached, I managed to set the GIS coordinate system code the Revit to be “Palestine 1923” in as per the screenshots below. However, as the Revit file is added to ArcGIS Pro if fails to gets located in the correct place.

 

What other issues I might need to consider?

I don't use ArcGIS, do people use it to land a building "corner" accurately or is it used as a macro, not micro, mapping tool primarily?

 

I'd go back to @syman2000 earlier recommendation, get an export from ArcGIS in DWG format and then use that to locate the building relative to the site portrayal in the DWG file. When you define Shared Coordinates with that approach you should find returning an export to ArcGIS will land much closer to what you expect.

Don't use Revit to locate your file in ArcGIS or it will give you unknown coordinate. Export it to DWG. Make sure your coordinate is set to shared.

 

syman2000_0-1691089590536.png

 

Insert your DWG and it will placed right where your location is set to.

dwg files can be added directly to the ArcGIS Pro without any required settings either at the level of Pro or AutoCAD. However, the dwg needs to be drawn in the correct place while the coordinate system in Pro needs to be (in my case) Palestinian Grid 1923. The dwg content is positioned in the correct place in the Pro as per the screenshot below

 

do you mean that I need to convert the rvt file to dwg in order to be able to place it in the correct position in Pro?

Yes use DWG export from CAD to make the coordinate works in ArcGIS.

I suggested for you to do some reading.  Have you done any at this point?

I could find a video that explains in details how to stick the Revit file in the correct location in ArcGIS Pro using the prj file

https://www.youtube.com/watch?v=Ap57raSTPx0

 

  • Use the “specify coordinates at points” command to define the correct location of the project by providing the correct location of one of the known point. In this case the “survey point” will move accordingly
  • Use the prj file for the coordinate system of your preference WITH SAME NAME AS THE REVIT FILE NAME in order to work as a georeferencing file (the rvt and prj files need to be saved in the same folder with same name)

This way the Revit will be positioned in the correct place in ArcGIS Pro
