How to rotate an entire project?

[Jonq12345]

Hi all,

I need to rotate my entire building of 90 degrees without change the value of the angle of the project true north. Is there a way to do that?

[Ilic.Andrej]

Well, yeah.... Select everything and then rotate

Rotate from a Site Plan view so you can select all levels at once....just to add to last comment.  So make sure your View Range will allow for everything to be selected.  FYI some stuff won't rotate, such as detail items and some dimensions may have to be force deleted.

If it is a central file...kick everyone out prior and detach...then save back after rotating and fixing stragglers.

I'm so sorry that you have to do this ....

Some tips - 

grouping the entire model may help to force hosted families to rotate

annotations placed on views will be crazy off

view types of existing views may also be crazy (interior elevation tags, for instance, may appear different) - you may need to create absolutely different view types

In order to re-annotate already created views correctly, what has worked for me in the past has been to hang on to an old local. That way I can refer back to the views and re-create and re-annotate them correctly without having to reinvent the wheel.

I tried to rotate it manually but the project north changes as well and the plan comes vertically but I need it horizontally. 

I need to have the same project north value of the site model..

Project North is entirely different from true North....

You may not need to. What do you need to rotate it for?

If it needs to match the Site Model then change the view to True North....if that has not been set then go to Manage-->Project Location-->Position-->Rotate True North. This will only affect the True North value and your Project North will remain.

[Jonq12345]

I need to rotate the true north because it is different from the true north of the site model. If I rotate it in the right orientation the value is different from the site because they have different project north. Am I right in saying the value of the true north depends of the orientation of the project north? In the site model I need the building to be vertical but in the building model I need it horizontal. 

As a workaround I used shared coordinate to align the building to the site, but the coordinate of the building model doesn't change, it changed only the coordinate of the linked building model to the site.

A proper workflow is NOT touching your Project North, your True North, your Project Base Point, your Survey Point; link the Site model in your file (center to center or origin or origin, doesn't matter), move and rotate it to align with your building, then acquire coordinates.  That will take care of everything you are trying to do manually.

[barthbradley]

I think you are a little bit confused. You don't need to rotate your Project. You need to Rotate the Link in your Project and then set up Shared Positioning via Acquiring or Publishing coordinates.  But, before I explain the process, I need to know what you meant when you say you rotated Project North.  Understand that Project North and True North are just View orientations, akin to rotating a piece of paper you are drawing on.   Project North is typically Project Orthogonal.  

So, what do you mean when you say you Rotated Project North?

BTW: Project North has absolutely nothing to do with Linking.  

[Jonq12345]

Thanks.

I've been asking by engineers to change our true north of the building because it doesn't match the true north of the site model (it's rotated by 90degrees from the site)

Even if I change it, they will not have the same value because the project north of the site and the building is rotated in a different way. So what I did is to publish the coordinate from the site to the building so that they can align once the building is linked in.

The engineer insists to want the same coordinate between building and site model even if they don't share the same origin. (So origin to origin doesn't allign)

Do you think is it the only way to do that? 

[barthbradley]

Forget about the Projects' different Project Norths.  Go to Project View's Properties an change "Project North" to "True North".  Is your building now rotated the way the engineer wants?  

[Jonq12345]

No because the building model has the same true north value of the site model...I thought they need to be the same even if they look orientated different in a true north view!

The me try this another way.  Is your Building correctly oriented on the Project Site that it is Linked into? Sounds like you are saying it is.  If so, select the building Link in the Site Project and then under it's Properties click on "Share Site" to bring up the "Select Site" dialog box.  Now, check the Radio Button next to "Publish the current shared coordinate system to"...blah, blah, blah.  Next, click on "Change..." to bring up the Link's "Location and Weather Site" dialog box.  Now click on "Duplicate" and enter a unique name (e.g. "Jong12345"). Click "OK" to close, and click "Reconcile" to close out of the "Select Site" completely.  Save and close out of Site Project.  Open your Building Project and go to a Site Plan View where your Project Base Point and Survey point are visible.  Now open the "Location and Weather Site" dialog box and select "Jong12345"  and then hit "Make Current" and then "OK" to close out and return to Site Plan View.   Toggle the View's "Project North" to  "True North".  Is the Building rotating? The Survey Point moving?  

[Jonq12345]

I tried that but it seems it doesn't moving anything. I'm so confused!

The building model is aligned to the site only by shared coordinate system, if I use origin to origin it doesn't work.

If I import the site model to the building by project point the building is rotated by 90 degrees and it doesn't change even if I change the true north value, it's always rotated by 90 degrees.

If I link it by shared coordinate again it works on the building model too.

So bidirectional linking works fine when you link via Shared Coordinates (e.g. projects are aligned correctly in each other).  Well, sounds like Mission Accomplished to me.    Are you saying it is not?

Here; I found this good resource for you that I think will help you wrap your brain around Shared Positioning concepts we’ve been throwing out at you.  It’s a good read by an excellent and well-known author. Take your time with it.

Also, note that part of the reason I posted the steps to create the “Jong12345” named site, was to point out that a while a Project can have MULTIPLE “True Norths” (e.g. named sites defined under Location Weather and Site) – it only ONE “Project North”.  In short, you don’t rotate your Building in YOUR Project – you rotate YOUR Project within the OTHER Projects and then set up Shared Positioning to establish an interlink between YOUR Project and the OTHER Projects.

Hope it’s up and coming for you.

Cheers!

Thank you very much for your help.

Even if the site and the building model are aligned by shared coordinate, I need them to be aligned by origin to origin or by project base point by project base point as it is easier when you export your model to external companies such engineers etc.

Both the models have the same survey point and project point coordinate (except for the true north).

The startup location of the project base point is different from each other.

If I link the site to the building (or viceversa) by origin to origin the building is located to the centre of the site rotated by 90 degrees.

If I link the site to the building by project base point to project base point, the building is located well except it is rotated again by 90degrees.

If I compare the project base point on both models the true north value is different only and I can also notice the little red and green arrows that appear when you click on the project base point rotated by 90degrees.

Is it possible there isn't a way to coordinate both without using shared coordinate system? 

If I rotate true north of the building, the site rotates as well, there's a relationship between the two models so that they always keep this rotation...
