In Revit 2015, you can use the IfcOpeningElement subcategory of Generic Models (and possibly other categories) for a Linked IFC to hide the orange “void” elements that appear in certain situations, as per this image:
Just use the Revit Links Display Settings to “override” settings in Visibility / Graphics (choose custom, and Model Categories tab also custom) to access this subcategory.
Lot’s of screenshots getting tweeted, like:

This video shows how Autodesk Vault interacts with Revit server and how to configure them both across different sites connected through a WAN. The demo at the end shows the workflow between different sites.
You will also notice the handling of a referenced DWG in a Revit shared project through Autodesk Vault Professional. The demo shows how and why the combination of Vault and Revit server is the perfect solution for cross-site collaboration.
Tekla have released a viewer app for iOS that can read IFC files. You will probably use Dropbox to get any large IFC files onto your phone or tablet, but you can also open from email or web.
Free version features
• View 3D models in multiple formats: .ifc, .3ds, .obj
• Very large models load in mere seconds, tested to more than 2 GB
• Zoom, pan and rotate 3D models
• Object Outlines and dynamic Shadows to better visualize model geometry and depth
• Open files from email, file-share or web
• Sample files included and more can be downloaded
• Orthogonal view of 3D models – as an alternative to Perspective view
• Imperial units display option for Property values (feet &inches)
Of course, you could also append the IFC to Navisworks, then Glue it, and use the BIM 360 Glue app to do something very similar 🙂
Mehmet Polat Diker has been busy doing some interesting Revit things over at Red Hot BIM. Like this little family that takes two dates and checks if the “deadline” has past or not. Some pretty detailed formulas here – nice work.
D_GEN_DEADLINE.rfa (Revit 2015)
The deadline family has 2 data entry parameters:
DateA and DateB. Family expects DateA to be earlier than DateB by default.
It has 2 check parameters:
DateAcheck and DateBcheck. These parameters show how the family interprets the dates we’ve entered.

If you paste a heap of elements from one Revit model to another, you may come across this error:
“There are identical instances in the same place. This will result in double counting in schedules.”
If you want to quickly select and delete the duplicate elements, here is one possible method. Basically, we are parsing the element IDs (every second one) from the Error Report and then quickly selecting them in Revit.
This relies on an Error Report that only has “identical instances” error messages (see images at end):
- Export the Error Report
- Open the HTML file directly in Excel
- Select all of Columns A and B, then Ctrl+C
- Switch to the XLS template (download here), click in cell A1 and Ctrl+V
- This will fill up the table, and using formulas it will find every second element ID. It ignores the first ID, because this “should” be the original one. The template file is good for around 600 data rows (255 identical items), but formulas can be extended to more elements if necessary.
(EDIT: the main concatenate formula is at its “limit” at Row 513, anything below this is ignored – Excel doesn’t like it bigger than this, so I recommend you either:
– do this operation 300 duplicates at a time or
– make a new concatenate formula for rows 513 to 1026 etc…
its still going to be quicker than clicking every duplicate manually in Revit 🙂
- Scroll down to the end of the data that you have pasted and click the Row Label for the first empty row
- Delete (this prunes the formulas and element ID list)
- Click in cell H3 (this has the list of element IDs)
- Switch to Revit and start the “Select Elements by ID” command
- Click OK
- Duplicate elements are now selected – press Delete
You might get some unexpected results (broken systems etc) depending on your project type. Use with care…

While many of us are struggling with a serious multiplication of models, Chris Price & Matthew Siebert have put together an interesting little case study on placing all design consultants in one model. Not just all using Revit – all in one single Revit model… Obviously, Revit Server (possibly plus VPN) or some sort of Remote Desktop scenario is required for geographically isolated teams, but there are definitely some pros to this method.
In my opinion, it would only work for models up to a certain size (a few hundred MB with all consultants isn’t going to be a huge building), after which I think it could become very difficult. Once you start segregating a model by sector or level, you aren’t in “one model” anymore. The other problem is that specialist subcontractors may not be using Revit at all (a post for another day). But the RTC Handout and Powerpoint is definitely worth a look. You will have to login to AUGI to download.
