Managing Shared Coordinates in Revit!

This video tackles Shared Coordinates in Autodesk Revit – a rather scary beast of a topic to most Revit users. The first half of the video is a summary of how to manage shared coordinates on a project, whilst the latter is a live demonstration of how to establish a shared coordinate system on a multi-disciplinary Revit project with multiple models.

I hope you enjoy the session and learn something new! Feel free to comment any feedback/questions below, or follow my channel if you enjoyed this.

I have been trying to figure this out for about the last 10 years! These two videos helped me a lot, and they bring up a lot of the actual issues you run into when coordinating models in the real world, like not having all the info at the beginning of the project, uncoordinated consultants, mistakes, etc. Great video, thank you!

This video and the "Aligning Revit models to DWG Surveys" cleared up a lot of confusions about coordination systems and showed best practice and trouble shooting for correct project setup, they are the best videos. Thanks Gavin.

Thank you very much for this video. Agreed, i was in the scared boat, until watching this video. It was quick, to the point, and very well done. Even with a little comic relief which made it more approachable. Subscribed to your channel after watching this video. Cheers!

Thanks for sharing this and all the other great in detail Tuts pal, they are incredibly useful for anyone with a serious passionate interest having a solid understanding of the software.

That's brilliant, much clearer for me now. thank you for sharing this mate!

THANK YOU SO MUCH!!!
It really made thinks a lot of sense and cleared a lot of things up! So thank you so much!!

Legendary video, , typical of yours man! really thanks

[oscarramosmartinez]

Thank out very much for the video, when you have multiple buildings in a project, would you recommend to set a different location (sites) for each of them?

[augustinpeytchinov]

Awesome video! Thanks! Question: not sure how you could model a building without first having a survey… you would have to design/position your building according to zoning restrictions. Accordingly, it appears that the site model and the architectural model MUST be done together FIRST and THEN you can establish shared coordinates- no? Also, how does this work with the BIM 360 workflow?

[iumepock]

Great tutorial! Many thanks. Just to be sure: once my architectural model is set, an MEP or Structural modeler can use my model's coordinate system to acquire the shared coordinates, correct?

[vivt]

If the arch did not set the coordinate can mep link to the site and publish the coordinate? What if mep have one host model that link to the base model. Which model should we use for the link to publish? Thk u

[bulkarchitects]

Sir make video on site modelling as per plot coordinates.

[zarnibo]

Hi, Thanks for sharing video, May I know we still need to do shared coordinates if we have the same boundary line, model, internal origin, project based point and survey point?

[xiaomi]

If one of the colleague rotate the project north in the service model, will it get back the same coordinate when we link in to the site model and publish the coordinate.

[javierperezmarin]

Amazing as always Gavin!! I was able to understand this difficult topic but, in case we don't have the survey file and we only have the google maps coordinates to locate the project (roughly) in the real world, would you just move the survey point with the coordinates eg. 13.7173° N, 100.5152° E, and move the project based point where it suits me best? How do you convert google maps coordinates to suit N/S and E/W parameters? How would you approach this? Thank you!

[iftekharkhan]

What happen if the site change i.e site rotate or n/s change ??

[aethelwolfe]

What do we do when the DWG surveys are super far away from zero zero zero?

[gabrielepiacentini]

Technically speaking it's all good and very clear. However, I think there is a problem related to scope of work / responsibilities. The process explained in the video shows the BIM Manager taking total control of the models (site, architectural, structural, etc.), getting to the point where he/she changes the coordinates of those models and save them back through the linked files, updating their position. I don't think this is what should be done. In reality, what the lead consultant (or BIM Manager) does is create the site (masterplan) model, which contains the right coordinates (X, Y, Z) and share it to the whole design team (architects, structural engineers, MEP engineers, etc.). Each BIM / Revit model manager within the respective discipline teams will then need to link the site model to their model and acquire the coordinates from it. This is what I've always done in order not to take responsibility of modifying someone else's model.

[Mnkas]

Very good material. Thank you!
I watched it and hoped to get my problem solved. Unfortunately. It seems like shared coordinates works well, because I'm able to link architectural model to my MEP one and they aligns perfectly. The problem appears when I try to export my 3D model to IFC by shared coordinates. After a first attempt, I opened both architectural and MEP models in IFC viewer and my IFC file appeared to be too low like 100 meters than architectural model. After second attempt, I ticked ifcSite elevation option, but the results were incorrect again: my IFC file appeared exactly 11050 mm higher where it suppose to be.

So you mean I Have to first Coordinate the Site model with Survey Cad file as you told in previous lesson . Am i right boss ??
