Host Model and link Model do not align.

Please help!!!

Hi everyone, I'm having trouble aligning two models in my project. The models are linked by origin to origin, and they share the same internal point, survey point, and project point. However, the models are not aligned in plan or elevation.

 Can someone please (explain like I'm 5)  how to align the two models and keep the same coordinates? 

Thanks!

  1. In your host model, in plan view, use the Align tool to align the linked model to your model, maybe using grid lines or edges of walls, in two directions, x, y.
  2. In your host model, in elevation or section, use the Align tool to align the linked model to your model, using levels.
  3. Select the linked model > in the properties window, click on "not shared", then from the dialog box click on Acquire Coordinates > Reconcile.

 

If the two models were already related by shared coordinates, you need to break that relationship before doing the steps above. To break it, you can click on the linked model, from the properties window click on the button that shows the name of the site, then click on "do not share coordinates". Then try the steps above.

Thank you very much for your help! I followed your steps and the model matches the location. The Survey and Project Points also match. However, the Internal Point is now shifted, so when the architect links our model by Internal Point, it will not align.

The internal point is shifted since I move the model and by acquire coordinate and reconciel the internal point do not move.

Am I missing something?

Internal Origin location does not play any role in sharing coordinates.  You can ignore the difference.

Thank you Toan, The Architect is linking my project by Internal Points, so my model do not align with them when they link my model, that has been the issue.

How do I "move" my model in Plant and Elevation to match the Architect model with respect to the Internal Point?

Help!

Simply use Shared Coordinates as your method for positioning models. Ignore the other method. The other parties will use shared coordinates as well.

You would have to move all elements in your model.  I do not recommend doing it but stick with using shared coordinates.  The architect and all other consultants will be using shared coordinates as well.  It is the only proven approach that works seamlessly among Revit links, CAD links, and Navisworks.

Alfredo Thank you for your help but that would no work for me.  As I said, Arch is linking our model by Auto-Origin to Origin, and Sharing the same coordinate will not resolve the issue.

Let's try this, How I make S-MODEL and A-MODEL to match the location of the walls at the same time that I keep the same Internal Origin distances from each model?

I can move S-MODEL's wall to match A-MODEL's wall but that do not sound correct and may bring another set of issue.

You either move every element in your model to the new location then fix all your views and sheets; or link your model to a new file, move it, bind the link, then redo all your phasing and documentation.  Either way a pain in the rear, a waste of time, and a source for all kind of errors.

 

Or simply tell the architect to link your model using shared coordinates.  What is the reason he is refusing to use shared coordinates?

Revit offers several methods for positioning. Don't worry if all those things (project base point, internal origin point, survey point, etc) are not exacltly the same from one file to another. Most of the times they are not because users start trheir models using different templates, etcetera. Shared coordinates is simple to use, and makes the position of those points irrelevant. After you do the steps I mentioned above, simply ask the architect to use Shared Coordinates to align your model, which for them is just a few clicks: they will select your model, then from the Properties window they will click on "not shared", then Move to (the name of your site), then click OK. And no more. Instead of you moving elements in your model.

Thank you Toan, That is the only solution I saw, but I asked to make sure there is no other way around.

 

I asked the Architect why they don't use Share Coordinate and they mentioned a bunch of not-sent justifications, So I went with what the client wanted.

 

Again Thanks!

Thank you Alfredo,

But like I said to Toan, the Architect is fixed with the idea that Origin or Origin is the way to go. I have already asked them a couple of times to do it but they don't want to.

 

My problem it is that I started the model from a set of CAD files so at the time I followed whatever location the CAD files had, but later maybe they changed the location.

 

So now I have to move the model manually, which I was trying to avoid.

"Origin to Origin" is not a friendly method of positioning, especially in a project with multiple disciplines. People start their models at different positions relative to that origin, usually without clear instructions from the architect's office, or because even though there were clear instructions, some users don't read those instructions.

"Project Base Point to Project Base Point" is more friendly, because all you have to move is the project base point to the same relative point in the project, like the intersection of two grids.

"Shared Coordinates" is the most recommended method, in my opinion, and I say that after working as a BIM Manager in two very large projects of theme parks, Universal Beijing and Epic Universe, with many buildings on the site and several disciplines per building. With shared coordinates, the position of those other points is not relevant. The architect acquires coordinates from a site plan. Consultants acquire coordinates from the architect's model. If the building moves in relation to the site, the architect resets coordinates, relocates the site in relation to the building and acquires coordinates from the site again, and then consultants reset coordinates and acquire coordinates from the architect again. It works. This also helps to locate models in Navisworks to see the whole campus or theme park together, because all the models are sharing the same coordinates.
