Project base point - survey point

[Anonymous]

Can I adjust the project base point / survey point to make up for a linked model that has been moved?  A consultant physically moved and rotated their building and now the landscape shows up in the wrong spot.  Rotating and moving the landscape objects are extremely problematic, and does not work.  Is there a way I can adjust so the landscaped is linked into the correct spot?

I assume I cannot publish / acquire their coordinates as the coordinates have not changed, just the location of the geometry.  Any and all advice is greatly appreciated.  Thanks.

Regards Peter.

Best thing you can do is shoot the consultant in question (the messenger will thank you for this as he feels in the past he's been unfairly targeted... ).

If it's been moved you will never be able to align it correctly using Origin to Origin but once aligned in your model it should stay there.  You will also be able to align it using shared coordinates if you have this set up.

there are quite a few threads on this type of thing already - one of which was only last week so have a dig around.

It is not correct to change the coordinates of your models to try to fix ths.

Try this instead:

• Create a group with your landscape elements.
• From the group tool panel, click on Link > Replace with new file
• Rotate the link > place pivot point and rotate
• Bind the link > Remove link
• Select the group > Ungroup

Give more specifics for a specific answer.
1. What is in each model? One site and landscape one building?
2. What did they move/rotate? And how? Only geometries? Did they use relocate project tool or they dragged it around or ... Or ...

I'm not sure why they rotate it...there is no real need to rotate a whole building! That's done or mitigated easier by orienting the link later in the master file and publishing coordinates!

Tell ur consultant to fire his revit operators as well as his bim bum manager

[Alfredo_Medina]

During schematic design of a large project with multiple buildings, it is normal to rotate or shift some buildings on the site.

It doesn't sound normal when one consultant moves and rotate stuff then let others wonder while tryin to figure out what happened and how to fix their models! 

I read an old post sometime ago on collaboration and I think it was Keith or Steve emphasizing on the importance of coordination off the REVIT platform as much as on it and the role of the BIM managers and coordinators being managers and not just draftsmen! I think it was Keith can't find the blog post!

if Peter's team is wondering then there is for sure something wrong and definitely some lack in comm. they shouldn't be left out to fix their models like that at any stage regardless if it is design or execution.

but hey 🙂 the guys here would definite find a solution for you Pete ... Lol you caught the attention of 3 of the most reputable Revit experts on this forum. So it should be a P Zee Breezy Eazee WEezee thing

Thanks for all the replies guys.  This is for a client that is a landscape architect, who has done some landscaping for an architectural site.  They have sub-regions and split regions in their landscaping model. The architect moved and rotated their buildings to be in the right place related to some other buildings on the site.  I basically told him that this should not happen but they didn't have control over that and want to move their landscaping to match the rotation and location of the architect's model.  They have tried to just move and rotate their landscaping which results in what seems like a departure of the model items.  Somewhat like moving things with different insertion points.  Not acceptable.

I will recommend them to follow the steps that Alfredo_Medina outlined and see if that does the trick.

I was wondering though regarding if each of these consultants moved their project base point / survey points to a common location and then one of them, the architect for instance, published their coordinates and the landscaper acquired them, whether that would suffice??  This is what I thought the publish and acquire was for?  Maybe I should read up on shared coordinates a bit more.  Thanks again guys.  If you know of any good links to clear this up for me, I would appreciate.

If both files still share the same startup location yes publish or acquire suffice (if the coordinates were shared the first place)...this is how one is supposed to do it in the first place

I find the best way to work is to have a 'Site' file in which all the consultants models are coordinated.  Ideally this site file is set up using accurate survey data and should have it's survey point set correctly to world coordinates.

Ideally each consultants model should be in the same location relative to the Revit Origin (the point Revit uses when linking Origin to Origin) but often this is not the case.  In such instances the best thing to do is to use Shared Coordinates which are controlled by the site file.

The site file should be issued to the team ideally with the issuers (architect usually) building model(s) already linked in - each consultant can then use this to locate their own model relative to this.  Once done, shared coordinates can be published to each model as required.  Then each model can be linked correctly using Shared Coordinates independent of the site file.

It's worth noting that once you have started modelling, unless you specifically need everything to align Origin to Origin (which is helpful but not essential) there should be no need to physically move this model - if the building moves on the site simply go back to your site file, relocated the linked building model and then re-publish the shared coordinates.

I have some notes on this that I've issued in the office which may help that I can send you if you forward me your email via PM.

Thanks guys - I used to work for a large architectural firm and I was in charge of starting projects.  I always did what you are suggesting and never had issues.  Now I work for an Autodesk re-seller / training company and see more of this stuff because the people calling / requiring our services are not that skilled with REVIT.  I guess it's good for me to force me to problem solve and figure out how this stuff works.

I want to be able to know this inside and out so any help is greatly appreciated.  Thanks again.
