Around 5 years back (where did that time go?), I posted about a free right-click Explorer extension that gives you some useful information on Revit files at a glance. CTC continues to update and provide that extension for free as part of its “BIM Project Suite”. All you need to do is:
install CTC BIM Project Suite
right-click on any Revit file to view its version and properties
This works for family RFA files and RTE files as well, and will give you an option to open in the actual file Revit version, or in any newer version you have installed.
Download: You can get the latest version of CTC BIM Project Suite on the App Store at this link.
The plugin ribbon will be installed in Revit versions 2017, 2018, 2019 and 2020.
Note: Seems like the “Open In” function will offer you any versions of Revit installed on your system, that are same as or newer than the file itself:

Changing and updating Shared Coordinates in Revit can be quite a challenge. At Virtual Built Technology we often create a Revit Control File to manage and transfer project datums, shared coordinates and other compliance items for the project team.
This video describes the techniques and challenges involved in updating and instituting shared coordinates on a Revit project. It also includes the steps involved in adopting other Revit modelling standards and requirements into your file.
Here are some of the tips included in the video:
how to un-share coordinates for linked models
how to acquire new coordinates
checking that coordinates are correct for linked models
using Transfer Project Standards – Project Info as a method of fixing coordinates
other model compliance steps including: updating base point settings, transferring Phase Settings, loading a Start View for the project
copying locator elements
copying scope boxes
using Dynamo to automatically generate the required worksets for compliance
I love Box. It is an incredibly robust file sharing tool and it has rarely let me down even though we have used it extensively on many large BIM and VDC projects. Recently, Box has been pushing people away from Box Sync and into Box Drive. I was syncing over 1 tb of data across many thousands of project files, so I could see the advantage of a more ‘on demand’ system. Box Sync actually struggles to scan through the entire folder structure – so much so that it sometimes never quite catches up in a 24 hour period. On the other hand, Box Drive uses a 25 gb transparent cache, and you can still mark certain folders to keep them offline. Another key difference is that Box Drive will always show you all of your files and folders, and it will download them on-demand (unless set to keep offline). This means that there is no web-based control for ‘Sync Folder’ or similar, the setting is basically on the client device.
A mini-install will run, and then you will be prompted to login
After you login, you will be prompted to uninstall Box Sync. You will have to make sure any files in Box Sync are closed.
I received this annoying warning a few times:
As it kept failing, I did have to restart my computer. The uninstall picked up automatically after the restart. Even after a long time ‘restoring disk space’ did not complete…
My workaround was to:
– boot into Safe Mode
– rename the existing Box Sync folder to “Box Sync.old”
– upon reboot, the Box Sync uninstall script thinks that it got the job done, even though I helped it along
Following this step, I wanted to move the Box Drive to the same absolute folder location I had previous, which was E:\BOX\Box Sync\contentfolders .By default it was pointing to a user location, that is C:\Users\lukes\Box\ .There are some notes here on how to do change the Box Drive folder location.
Restart Box Drive after setting the CustomBoxLocation Registry key shown below:
Unfortunately, this did not have the desired effect. It resulted in a folder structure like: E:\BOX\Box Sync\Box\contentfoldersAnnoying! So you can’t actually rename the \Box\ piece of that folder structure…
My next plan to work around this limitation was:
– put Box in a different folder, and
– make a symlink to the new folder.New location in Registry:
Finally, I made the symbolic link like this:
mklink /d "E:\BOX\Box Sync" E:\BOX\Box
Now, I can use all of my legacy Box Sync links with Box Drive, and they will all correctly redirect to the new Box Drive location.
Obviously, you have to go through now and ‘Mark Offline’ any folders that I want to keep permanently syncing to that device.
Update: Changing the Box Drive Cache Folder location
I discovered the Box Drive cache was using heaps of hard drive space
So I decided to move that cache folder using yet another symbolic link… Here’s how:
As software and standards mature and even become archaic, they inevitably attract baggage along the way. Years of technical debt amassed by well-intentioned developers and product managers will be paid for by us and our children.
This is particularly evident when we start talking about the Id of Revit elements, and the IFC GUID syntax. As most of you are aware, Revit carries a number of different identifying attributes for each and every element. Here is a basic list:
Element Id – the numerical form of a Revit Id, you can interact directly with this using the Select By Id command in Revit
UniqueId – “A stable unique identifier for an element within the document.” This is not a correctly formed UUID, but rather a concatenation of a standard UUID for the Revit EpisodeId (session based), along with the Revit element Id. From Jeremy’s post: similar to the standard GUID format, but has 8 additional characters at the end. These 8 additional hexadecimal characters are large enough to store 4 bytes or a 32 bit number, which is exactly the size of a Revit element id.
DwfGuid (Export Guid) – this is a correctly formed UUID in .NET / standard format
IfcGuid – identical to DwfGuid, but encoded differently according to IFC rules created in the mid-90s. At the time, it was deemed worthwhile to ‘compress’ the IFC Guid to the shorter form we still have to deal with today.
It would be nice if Revit and IFC shared a single common unique identifying syntax, but unfortunately this is not the case.
The above Ids do actually bear some predictable relationship to each other. The UniqueId is formed by Revit joining the EpisodeId and the encoded Element Id, the Dwf or Export Guid is created by an algorithm that has a number of conditional rules, and the Dwf Guid can be converted to the backwards-compatible IfcGuid format through a different algorithm, originally created in C. Those algorithms can be sourced in various places (see links in Further Reading below).
Also, some of these get exposed in different ways – if you create Element-bound BCF files, they will typically show the IFC Guid syntax. Further, if you export an IFC file from Revit and tick the option on the Exporter, it will write the IfcGuid to a parameter on the element.
You can query the Element Id directly in Revit (Modify ribbon, Inquiry panel, IDs of Selection):
However, for the purpose of this post, let’s assume you are using Dynamo with IronPython, and you want to query all 4 Ids from an element.
We at least need to import the Revit API and the Revit IFC API:
from Autodesk.Revit.DB import *
from Autodesk.Revit.DB.IFC import *
Following this, we can use the various Dynamo and Python commands to access the Ids:
elementIds, uniqueIds, DwfGuids, IfcGuids, successlist = , , , , 
for i in e:
OUT = elementIds, uniqueIds, DwfGuids, IfcGuids, successlist
Notice the commands and properties used:
Element Id – query the Element.Id member
Unique Id – query the Element.UniqueId member
Dwf or Export Guid – use the ExportUtils.GetExportId method
IfcGuid – use the ExporterIFCUtils.CreateSubElementGUID method (index 0 refers to the main element itself)
From here, I create a Dynamo node that eats Revit elements and gives us back these Id values:
This node will be published in the Bakery package on the package manager, and to Github.
Further, our VirtualBuiltApp platform has been developed to store and query multiple Ids for a single element.
Example output from the Dynamo / Python (initial test showed the Dwf Guid is still a .NET object, that probably should get converted to a string for consistency).
[<System.Guid object at 0x0000000000000071 [c98618bf-7112-4e90-8a71-8ab768f2b8b8]>]
I added str() to the Python:
Final test showing the 4 different Id values for a single object:
Disclaimers (use at your own risk etc) and notes on how to use the scripts are as per previous post.
Here is the note from Thomas:
Hi Luke, I have used your script from https://wrw.is/script-to-disable-all-revit-addins/ and I have adjusted it a bit. I have local users without admin rights (training center computers), so I go to the users computer, open the file with rightclick > Powershell and the Admin login is shown. I got also some problems with the allusersprofile and the appdata path variable, because as soon as I login as admin, the appdata path is not anymore the user path. Thus I have changed it to the path itself. The last 2 lines help to see the errors.
Thanks for your script, it helped me a lot! My scripts are attached if you want to use it on your blog =)
Thanks to Thomas Vogt for sharing his work on this!
