Shared Coordinates Not Transferring in Shared Survey Point

[ashleyo5]

I have two models. One is a Site model that has the Survey Point and Project Base Point at a State Plane location. I linked my Revit model to the site model. Placed it at the appropriate location, at the proper rotation.

• I publish the coordinates FROM the site model TO the Architecture model. 
• I click on Manage Links, and save the coordinates to the architecture model. 
• When I open the architecture model, the Site Point is at 0,0, not where I specified it, and the Project Base Point is at the correct location. 

Shouldn't the Site Point be at the correct location, and the Project Base Point be at the location of the corner of the building in the Architecture model?

This makes my Revit model not load properly in an external GIS application and is causing great heartache.

I think it is confusing but the Survey Point "icon" marks where it sits on the Survey Coordinate system while the Project Base Point (PBP) displays its position relative to the Survey Coordinate System. If the PBP displays the site related coordinates then Publish Coordinates worked. If the Survey Point reports 0/0 it means it is sitting at the origin of the Survey Coordinate system. If you un-clip the Survey Point and move it you'll find it reports values that start to relate to the survey's coordinates for your site...once you get it closer to the project location.

Did you publish to a named site? How many sites does the project show on the Location Weather and Site Site tab? Maybe it's one of the other ones.

So, my issue is that I don't want the Site marker to be at 0,0 in my linked model. The 0,0 point in my state plane system is in the Gulf of Mexico, and it is problematic in both the GIS interface as well as the linked Revit model.

Is there a way to make the Site Point from the Site Model NOT be 0,0 and be at the same point as my Site Point in my Coordination model?

[barthbradley]

The Survey Point marker doesn't need to stay at the Survey Point Origin. You can unclip and move the marker to wherever you like.

[ashleyo5]

I understand that. I want the Publish Coordinates from the Site Model to tell the Site Point in my linked Architectural Model that the site point is not at 0,0. I don't want to have to move it. We are automating the process, so this needs to be able to happen automatically. I understand I can manually move it, but I want the Publish Coordinates to do it. Otherwise, why even have it?

[barthbradley]

If you Publish Coordinates from the Site Plan Project to the Linked Architectural Project, the Survey Point in the Architectural Project will be affected.  If you Publish to the default "Internal" Site of the Architectural Project, then when you open you Architectural Project, the Survey Point Origin for the "Internal" Site will be positioned -- relative to the Architectural Project Model -- exactly as it is in the Site Plan Project.  If it was 1000 miles North-West of the Architectural Building Model in the Site Plan Project, it will be 1000 miles North-West of the Building Model in the Architectural Project.   Is this not happening for you?  

[ashleyo5]

No, it is not happening.
It just always sets the Site Point at 0,0- regardless of Publishing Coordinates to the Site Plan Project OR to the internal Site of the Architectural project.

Okay, so the SP is sitting at its Origin.  Is that Origin sitting in relationship the Architectural Model, the same as it is in the Site Plan?    

[SteveKStafford]

Publish Coordinates does one thing. It moves the Survey Point and Survey Coordinate System origin to match the World Coordinate System origin defined by the survey source data. That assumes a CAD source. If there is no CAD source then it just matches the Survey Coordinate System of the host model.

Regardless the Survey Point icon is located at the origin of the Survey Coordinate System. The only way the Survey Point can be located elsewhere is when it is un-clipped and moved. I don't know if the API will let you do that. I'm pretty confident that you can't do that to a linked file since the ONLY operation allowed to alter a linked file is Publish Coordinates AND that can't even be done in the BIM 360 world.

What you can do is make sure the Survey Point is un-clipped in the linked model FIRST. Then using Publish Coordinates should leave it at the same location as the Project Base Point, the default location.

[ashleyo5]

No. 

On the Site Model, the Site Marker is at the same location as the Project Base Point. 

In the Architecture Model, the Site Marker is at 0,0, and the PBP is at the same location as the PBP and Site Marker from the Site Model.

[barthbradley]

Wow, getting confusing here.  What's the Project Base Point have to do with it? The PBP is not affected when Sharing Coordinates.  If the Survey is reading 0,0,0, it's sitting on its Origin -- the one you Published from the Site -- assuming that the one you Published is the CURRENT Site that is activated in the Architectural.

How many sites are listed under the Site tab of Location Weather and Site in the Arch project?

[ashleyo5]

I have tried it many different ways: 

Only one site (the default one), and adding another one. The answer is still the same. The survey point defaults to 0,0, which I do not want. and the PBP is where it was in the linked model. 

[barthbradley]

Okay, the PBP doesn't factor in. So, let's take that out of the equation. Regarding the Survey Point Coordinates you are seeing; that indicates the MARKER is sitting on top of the Survey ORIGIN. Again, that's what you Published. Now the Marker itself can be UNCLIPPED and moved whatever you want it -- in either Project -- and its ORIGIN will stay put. However, when you do this, the Marker Coordinates will change to reflect the x and y distance it is moved from it's Origin. Sounds to me like the Marker reads 0,0,0 in both Projects, which means it hasn't been moved from its Origin.

So, do this: in the Site Plan with your Arch. Linked into it, draw a big 2-Point Circle with the 1st Point smack dab on top of the Survey Point Origin and 2nd Point smack dab on some point in the Architectural Link, such as a building corner.  Make the Temporary Dimension of the 2-Point Circle Permanent and note the Radius Dimension.  Now, open the Architectural and do the exact same thing.  Do the Radiuses (Radii) match???

[ToanDN · Accepted solution]

Try the other way around. Link the site model into your project model, move/rotate it to match, then acquire shared coordinates.

[ashleyo5]

Ah, this actually worked!

Also, it involved a sequence of clipping/unclipping both the Site Point and PBP.

Thanks so much!

I don't recall any mention of BIM 360 but if the project is hosted there then the Publish Coordinates feature isn't available or possible. Acquire Coordinates is possible however.
