A note on C4R Update 9 and Revit 2015 Update 12:
Users of A360 Collaboration for Revit may experience an error on Revit startup if they install the Revit 2015 R2 Update Release 12 but not the corresponding A360 Collaboration for Revit update, version 2015.9.
The error dialog will reference the following: File name: ‘Autodesk.RevitServer.Versioning.Client,…..

  • To continue using A360 Collaboration for Revit, close all sessions of Revit, then download and install the Collaboration 2015.9 update and restart Revit.
  • To stop using A360 Collaboration for Revit, uninstall this program via the Programs and Features functionality of the Windows Control Panel.

I’m sure you have probably seen this message before:
Can’t edit the element until ‘problemUser’ resaves the element to central and relinquishes it and you Reload Latest

This may be caused by one of your team members not syncing with Central, and then experiencing a crash, or just logging out and going home. Before you send off an angry email, perhaps you could use one of these methods to get rid of the element locks and keep being productive. Method 1 is a bit more disruptive to a large team, while Method 2 is a bit more ‘hacky’. Important: Both methods will mean that ‘problemUser‘ has lost their work and will have to redo it.

So, maybe Method 0 is ‘call problemUser on the phone’ and see if they want to come back into the office to try and sync their work back to Central… but if that isn’t an option, you may have to use one of these methods:

Method 1 – Recreating the Central File:

  1. Notify all team members to Sync with Central and Close Revit
  2. Make a copy of your current Central file and _backup folder and put it somewhere for safekeeping
  3. Detach from Central
  4. Save As Central – overwrite the same file
  5. Notify your team members to open the model again, using ‘Create New Local’ tickbox


Method 2 – Using a Known User Name to Relinquish Element locks

First, make a note of the user name that has the lock. In the image below, it is ‘rds check3‘:


Open a new Revit instance and set that as the user name in Options:


Open the model normally (Create New Local) under that user name, and immediately click ‘Relinquish All Mine’…


… and then Synchronize with Central. The element locks should now be gone.


In one of the other model instances (ie. your own user name), you can now Sync with Central… (or Reload Latest)


… and you can successfully modify the element that was previously locked.


As usual, the best idea is to do What Revit Wants and Sync with Central regularly so that lost work is minimized.

Translated quote:
Please download the macro down here: Download DeleteStandardMaterials

  1. Connect Revit.
  2. Unzip the zip file. The ZIP contains a DeleteStandardMaterials folder with two subfolders (AddIn + Source).
  3. Copy the addin + Source folder on the following path: C: \ Program Data \ Autodesk \ Revit \ Macros \ 2015 \ Revit \ AppHookup \ DeleteStandardMaterials
  4. Start Revit.
  5. Open the file.
  6. Open Manage / Macro Manager / Application tab: The macroDeleteStandardMaterials” appears under the Application tab.
  7. Select “Execute” and start the “Run” command. > The standard materials are removed.



I posted the links recently to download Update 11 for Revit 2015, over here. Unfortunately, this update causes problems with Revit Server.

While there is no official hotfix (yet), you can still have Update 11 and Revit Server if you follow one of the 3 methods at this link to fix your Revit install:
Revit 2015: UR11 breaks Revit Server | Revit Products | Autodesk Knowledge Network

Method 1 involves modifying Autodesk.RevitServer.Social.dll, Method 2 involves modifying Revit.exe.config, and Method 3 recommends not installing Update 11 (?)

Check the main article for the detailed steps.

Update 11 for Revit Structure 2015:

As per this tweet, you can find it on your Autodesk Account under Product Updates:


Here’s how:

You would like to assign OmniClass numbers using the 2012 standards but are not able to because the default file shipped with Revit provides numbers from the previous standard.
Symptom: When trying to assign OmniClass 2012 numbers in the family editor the numbers supplied from the table are incorrect.
Issue: The OmniClassTaxonomy.txt file installed with Revit is an older version of the table. The file installed with Revit needs to be replaced with the updated OmniClassTaxonomy.txt file which can be downloaded here.
Solution: Download the attached file and follow the procedure to update the file in the Revit installation.
Note: The AppData folder is a hidden folder, so you need to first enable the viewing of the hidden folders on your system before performing the procedure.
  1. Navigate to C:Users\AppDataRoamingAutodeskREVIT Example: “C:Users\AppDataRoamingAutodeskREVITAutodesk Revit 2015”.
  2. Rename existing “OmniClassTaxonomy.txt” to “OmniClassTaxonomy_bak.txt”.
  3. Copy the downloaded file to this location. Repeat this processfor each user on this local machine.
  4. In addition, copy the file to the following location. This step ensures that any new future users of this computer will get the updated file. C:ProgramDataAutodesk\UserDataCache Example: “C:ProgramDataAutodeskRVT 2015UserDataCache.
  5. Repeat process for each Revit product installed (RAC, RME, RST….) as needed.
Note: When using the updated OmniClass file, category sorting is not available. You must manually navigate to the correct category to assign an OmniClass number.
