Our Mechanical department began work on a project before the other disciplines by using an AutoCAD background to start roughing out their design. However, when Architecture finally created their model they used a different origin so that when it was linked into the Mech file it was way off. The Mechanical department was able to adjust their project base point and the link locations so that all of the other disciplines' links appear correctly in their model. The mech file doesn't appear correctly for the other disciplines and they want mech to fix they're model. I've spent quite a lot of time trying to help fix this problem and haven't been able to come up with a solution. This also effects our Navisworks exports and needs to be corrected.

A good set of steps to follow would be most helpful as the current documentation on Project Base Points is lacking any clear explanation on how or what needs to change. I'm certain it's a very simple task, it's just eluding me at the moment.

From an older post...

 

"You can establish coordinates for a specific location in your project under the manage tab / project location / coordinates. You can publish these coordinates to other linked files."

 

You can read more about this in several topics of your HELP. Just search for coordinates.

Yes, we've published and acquired coordinates back and forth. Sometimes using the Move To Internal moves things, sometimes not. It's not clear to me why one link will stay where it is and others will move, and the search under HELP isn't clear in how to troubleshoot a coordinate issue. It covers how to set up a file, not how to fix one that's set up incorrectly.

I wouldn't be asking for help if I could find the information I need in the HELP wiki or in other posts. If you read my post I make it clear that I've read the HELP wiki and found the information there useless or confusing in regards to my situation.

 

* rant *

I find "use the search function" replies useless and demeaning and only inflates ones post count. IMHO one should not reply to any post if one can't contribute a useful comment. It's trollish and a copout and wastes everyone's time reading a response when no response would have been as effective. Are there people that don't use the search function first? Sure, but I'd still try to provide them with an answer just as I would if they'd come to my desk and asked. I expect the same level of comportment online as I would in RL. I may not have a high post count but I help out when I can, or I don't say anything.

*end rant*

In your post you do not state that  "I've read the HELP wiki and found the information there useless or confusing in regards to my situation."  A lot of people do not take a look at their own help or search other threads before asking a questions.  I was trying to help hence why I stated "You can establish coordinates for a specific location in your project under the manage tab / project location / coordinates. You can publish these coordinates to other linked files." I said this because I thought it may help you.  If you are just going to whine and complain about getting a response then perhaps you won't recieve one next time.  Not every answer that you will recieve will be to your liking.  I apoligize that my response was not helpful to you but that doesn't mean that the information was not good or a correct way to establish coordinatns.

Gyvven,  teafoe gave you the best initial advice since you said nothing about reading your HELP and that is where you needed to start.

 

I am a big proponent of recommending users learn to use the HELP file. Unlike many programs, Revit's Help is very well documented if you learn how to use it. AND BTW - I hate the wiki-help!!!!! You can turn that darn thing off so that you can use the installed Help.Wiki just adds user garbage :

To reset the Help pointer, I wrote this for 2011.. 2012 is different and I have not rewritten it yet

In your Revit.ini file set this:

UseHelpServer=0

HelpBrowser=0

You also need to set the locally installed help such as: ENUHelp.cab=C:\Program Files\Autodesk\Revit Architecture 2011\Program\

 

You have since written that: ".. we've published and acquired coordinates back and forth. Sometimes using the Move To Internal moves things, sometimes not." <<< You don't understand.  This is NOT both ways.  You indicated a linked CAD file.  So since it has already been created

  1. you have to place it in your project in the correct place manually.
  2. Then you publish coordinates.  From the HELP it explains: "When you publish shared coordinates from a host Revit Architecture project to a linked DWG, this changes the linked DWG. The origin of the host Revit Architecture project’s shared coordinate system becomes the origin of a new User Coordinate System (UCS) in the DWG file. The Y axis of the new UCS corresponds to the host project's True North. You can name the UCS when you publish coordinates. It is not recommended that you change this name after publishing coordinates."
  3. Now that this information is in the shared CAD file, you have to give it back to them!!!!! How else would they get the coordinates.
  4. They can no longer move their file!

 I thought my comment "...as the current documentation on Project Base Points is lacking any clear explanation..." would indicate that I had looked for the answer. I admit my response to yours was stronger than it needed to be, but I've seen far too many replies to people with legitimate questions that are less than helpful. On the other hand I see many good contributers on Revit City, including yourself, but I was disappointed by the "use the search" response.

WWHub,

Yes, the Wiki HELP is the worst help I've seen Autodesk put out. I'll adjust my .ini as you suggested.

 

You are correct that I don't understand how the shared coordinate system works. When I say we've tried acquire and publish coordinates, we tried acquire first and tested the results, then we tried publish and tested those. Then we tried moving some of the linked files to the internal site position, some of them stayed in the correct place and others moved. I'm trying to understand why that is, and I'm sure it has something to do with project base point and acquiring and publishing coordinates. The DWG is no longer an issue as it was only used for SD planning and disappeared after Arch created a model.

I don't know how Mech used the DWG to begin their model, I just know that when Arch made their model the Mech model was 799'-1 105/128" East and 221--5 35/256" South of the Arch project base point. Tried moving the project base point, clipped and unclipped, with unsatisfying results. I'm sure it's an issue of doing the right steps in the right order to relocate the Mech model in the other disciplines models. And as I mentioned, the Mech Navisworks exports are also in the incorrect position.

 

Most projects the disciplines wait for Arch to create the model, but I guess Mech got anxious and used the planning SD DWG file to start work thinking moving or adjusting the model later should be easy.

OK.... Then if your Arch file is located correctly, then the MEP should place it correctly in their file then MEP simply follows the HELPs direction:  (NO NEED FOR YOU TO DO ANYTHING ON YOUR END)

Acquire Coordinates
 
 
 

 

When you acquire coordinates from a linked Revit project, the shared coordinates of the linked project become the shared coordinates of the host project, based on the position of the linked project instance in the host project. There is no change to the host project's internal coordinates. The host project also acquires True North from the linked project. The origin of the linked project's shared coordinates becomes the origin of the host project's shared coordinates.

 

BUT the MEP does not then publiash anything!

Hello WWHub,

I've succesfully published and shared coordinates between my host and linked files. However, some of my linked files need to be rotated and I was wondering if there was a way to republish these coordiantes in the linked file. Whenever I do republish the coordinates in the host file, it does not update in the linked file. Any thoughts?

Thanks in advance!

Also the warning I get when I try to save postitions in the manage links tab :

"Local file not synchronized. To save your changes to the central model, from the application menu select Save As to create a new local file with a different file name. Then select Synchronize with Central. The file was not saved because one or more links failed to save."

I wish the linked file could just be saved over, instead of renaming it over and over again. Is there a way around this?
