is there an easy and appropriate way to move entire project (building) close to Internal Origin

[zhounnin]

i tried "Relocate Project", seems not work as expected, the reason is for BIM 360 (google) map location, seems the Revit project address will only respect Revit Internal Origin (not sure yet?), so correct project address doesn't necessarily mean correct BIM 360 (google) map location, maybe factory should clarify on this issue?!

cool, how do you get that dialog, i'm using Revit 2022 already.

cool, how do you get that dialog? i'm actually using Revit 2022, seems no such OOTB dialog box.

I'm pretty sure @ToanDN was joking.

that's what factory (one of Forge development team) told me, but seems not always the case, especially when shared coordinates is used, hope anyone here or factory can verify it?!

The guys from Forge might have either misunderstood your query or assumed by default that you have the project location already defined. 

In Google similar to Bing and/or Openstreet you need to provide a bounding box or  geogrid for those application to translate the location of your Revit model from the Cartesian system to WGS. That is how you georeference a project, by locating its survey point with respect to a specific/recognizable location aka Address and not vice versa.  And you do the above, you do not need a CAD to acquire coordinates from ...Simply go to Site and Location and pick the nearest city to your project 

PS: You do not need to move the project closer to the IO (from what you described it seems fine as it is). Both survey point and Internal origin coordinates in Revit will not be affected but you will need to update the shared site between all links considering that the project location has changed

thanks RDAOU for the insight.

in fact, my Revit project location is defined correctly,  i did another test, seems survey point DOES affect the project location in google map, my test as below:

1) same Forge app

2) same Revit project location

3) old RVT w/ Survey Point at N/S 832367930.5 and E/W 816832399.3 -> project building will be "floated" on ocean in google map

4) new RVT w/ Survey Point reset to N/S 0.0 and E/W 0.0 -> project building will be located correctly in google map

i need to ask Forge development again.

@zhounnin 

The values/units you listed for the N/E coordinates of the survey point are with respect to WCS...how does your app in FOrge handle the conversion from WCS to WGS-8?

The way it seems, you are taking coordinates from one system and using them without conversion in another system... If I would do the same in Dynamo, I would take the coordinated of the SP/PBP and translate those to the relevant WGS of my location then use these values and not those you read in the model

thanks RDAOU, i filed the Forge support to see how to solve this issue, looks like their Forge google map extension (default) reads survey point.
