Workarounds for "No suitable geometry found when exporting from Revit to Navisworks 2015"

On latest R2 version of Revit 2015, with Navisworks 2015 SP3 and Navisworks Exporters R3, there remains a Navisworks export bug that affects some projects after upgrade from previous versions of Revit.

Error: documented at

Workaround: You can use the selection method to Export and the error does not seem to occur:
  1. Open the 3D view to export 
  2. Select all visible objects 
  3. Go to Addins ribbon, 
  4. choose External Tools - Navisworks 2015 (Exporter) 
  5. In the settings, choose "Selection" (see attached screenshot) 
  6. Name the file and export as usual

Other suggested workarounds (did not work in this instance):
  1. Turn off Detail Items
  2. Try exporting again
  1. Remove View Template
  2. Set Level of Detail of view to something other than Fine
  3. Set Level of Detail of categories in V/G to the setting you desire (can be Fine)
  4. Try exporting again 
Try turning off categories one at a time to find out which Category the problem geometry resides in.
The log file reports:
Autodesk.Revit.Exceptions.ExternalApplicationException: Object reference not set to an instance of an object.
   at Autodesk.Revit.DB.CustomExporter.Export(View3D view)
   at NavisWorks12.LcIRevitBase.Export3DView(View3D view_3d, StateDictionary state_dict)

Download beta Excel sheet to build and manipulate Revit IFC mapping tables

Teun De Vries shared an: "Excel document (download), with which you can build the mapping tables that Revit can use when importing from, or exporting to IFC. It is still a b├Ęta. You can use it or even change it, but at your own risk of course. And if you do so, Teun would love to know what your experiences are. The RevitGG is also using this tool to help build some parts for in the Dutch Revit Standard the DRS."

Changing Pipe from One System to Another (and Undefining MEP Systems). Plus upgrading Systems to Revit 2015...

To change the System Type for the connected run, Tab-select until you have the System, then change the Type. You can also change the name here.

To completely undefine pipes, tab-select the system, then delete it. Pipes will become undefined. Start Draw Pipe command from one end and a new name will be automatically created. Apply System Name and System Type as above.

Changing Pipe from One System to Another

and here is how you can break systems up by using a custom family with multiple connectors:

Breaking up Pipe Systems

Note on upgrading: we discovered an interesting thing in the Design Office recently. When upgrading Revit 2013 files containing Systems (in this case Pipe) to Revit 2015, it is highly advisable to install the latest update (preferably R2, which is roughly equivalent to Update 4) prior to upgrading. If you use the 'initial release' version of Revit 2015, it will come up with lots of warnings if you have systems with duplicate names. However, it appears that the R2 version will automatically go through and un-duplicate the System names for you, making them all unique. Obviously, there may be a situation where this is not desirable (tagged systems linked to quantity takeoff or something), but for the most part it is nice to have all of those errors / warnings fixed during the upgrade to 2015.

Re: Pipe System to same Pipe System of a different... - Autodesk Community

Entourage Workshop will allow you to override individual RPC styles in Revit (by Archvision, new feature coming soon)

It allows for greater stylistic control of RPC elements, and facilitates a greater level of artistic style in native Revit visualization.

Check out the video:

Collaboration for Revit is coming, Multi-firm concurrent authoring without complicated IT and LAN setup

I'm pretty sure this is what Revit Skyscraper is going to look like when it gets released, and I'm guessing it will be called "Collaboration for Revit" or "Revit Collaboration" (sounds like an addin, yeah?). Check out the image:
Those features again:
  • Multi-firm concurrent authoring
  • No IT setup required
  • BIM directly accessible to other Cloud Services

I'm not breaking NDA as this was a mailout from CTC, and you can register for the webinar here.

A different take on the LODs

Posts and articles about Level Of Development are so prevalent, and they can tend to be repetitive, or controversial, or somewhat tedious (or is it just me?) But recently I thought of a different way to look at LOD. What if you take the perspective of the individuals or teams who have to deal with a given generation of data? How does that relate to LOD? Here's one way it could be expressed:

The Client says "We want something that will maybe look a bit like this"
The Architect says "OK, but here is a more realistic and developed idea of the design"
The General Contractor says "Nice design, but here is something that is more coordinated and 'buildable'
The Trade Contractor says "That was close, but this is how it is actually going to get fabricated and put together"
The Builder Operator says "Let's take some of those 3D models and as constructed documents, and figure out what is actually going to be useful moving forward"

Automatic Batch Printing and Exporting from Revit that could save you Dollars and Time (RTV Xporter Pro review)

Automation is the key to productivity. Don't we use computers so that they can do the repetitive, boring stuff while we focus on the creative, interesting things? In BIM world, if there is something that is repetitive and requires little or no user interaction, it should be automated by some addin or script. RTV Xporter Pro is a great example of this.

Basically, it allows automatic exporting to a number of different formats, with little user interaction required. You can set up task schedules to export the formats that you need, from the Views or Sheets in your Revit model. You can use parameters from inside the Revit model (Views, Sheets, or Project Parameters) to automatically generate the correct names for the exported files. You can even integrate with the built-in Revision Schedule in Revit.

Coming from an architectural documentation background, I have spend many hours trying to find quicker ways of doing exactly these things. But RTV Xporter Pro takes a lot of the pain and guesswork out of it - you don't have to reinvent the wheel, just use this to get the job done. My current work is more on the subcontractor side, and I have seen the time involved in generating deliverables that need to comply with certain requirements. This addin for Revit can help automate these deliverables, meaning you have more time to meet other deadlines.

This review is a collection of tip, links and resources to help you see the value in RTV Xporter Pro, and hopefully give you a head start in using the tool to accelerate your productivity.

When launching the addin for the first time in a Project, you will see this screen:

If you don't need to use Project Parameters, click "Don't load Project Parameters"
Once the pane loads, you will be able to choose between the Revit Sheets and Revit Views tabs. On the right, you will see a Batch Process section. The two little arrows can add selected items from the left (current Revit model) section into the right (Batch) section.

Exporting PDFs
... is very easy. Just add the Sheets you want, then click the Export button in the top-left. Tick the PDF box, and set any options you would like for target folder and naming, then click OK. Done!

3D Deliverable Export
What about exporting multiple views to DWF, DWG, FBX, IFC and NWC with the click of a button?
  1. Start RTV Xporter, then
  2. Add the Views you want to export to the Revit Views tab. 
  3. Click Export in the top left
  4. On the Export Views dialog, flick through each tab and set the options you would like. (Notice how the settings you see in the top of this dialog are essentially the same as the settings you would see in the DWG, IFC, or NWC export dialogs in Revit.)
  5. Set each export tab to suit your preferences
  6. Tick all the filetypes you want
  7. Set output folder
  8. Set File Naming Format
  9. optional - Click Save to save your settings to an XML for future use or scheduling
  10. Click OK
  11. Do some other work in another instance of Revit, or grab a coffee
  12. Come back and transmit your files to the required parties

RTV Xporter can load and edit your Revit Revision Schedule. This means that there remains one point-of-truth for Revisions, and it is stored in your RVT file - great! Additionally, the View / Sheet Set selections are also read and written by RTV Xporter straight into your Revit model. There is no external database to manage, and I must admit, I love that.

As you can see, this addin could become an integral part of the way you handle the creation and transmission of documentation. It provides a powerful yet simple automation engine, that integrates well with native Revit capabilities. I recommend that you give it a try...


Once you have purchased a license,  RTV Xporter Pro is activated using the send email request... receive activation code method.

  • output to multiple formats at one time
  • automatic naming (including revision)
  • print to two different printers at the same time
  • batch processing (unattended)
  • task scheduling
  • uses native Revit Revisions
  • can use Sheet, View or Project Information parameters in automatic naming
  • ability to Check for updates from inside the addin
Advanced Features (some are 'coming soon'):
  • new Transmittal function (RTV Xporter and RTV Drawing Manager share some of the same space but the Xporter is built to work on top of Revit's internal functions where as the Drawing Manager has been built to extend Revit functions, particularly revisions and giving users in the UK an option to comply with BS1192)
  • remote processing server for Revit, which will allow you to send printing and exporting jobs to a PC other they your own for processing, like backburner for rendering in 3DS Max
  • new file export extension to export Revit files to GSI via Safe Software's FME Server

Output formats:
  • DWF / DWFx
  • DWG
  • DXF
  • PDF
  • IFC
  • NWC
  • Drafting Views (as RVT)
  • FBX
  • DGN
  • RVZ
Configuration and Deployment:
Batch settings can be saved to XML to allow for easy sharing of consistent options

Right-click in the data grid to see various ways you can manipulate it (add columns, filter by columns and rows etc)


Tutorial videos:

I also reviewed some of the course material for the official Xporter Pro 2015 Training course, and there were some good step-by-step guides to get you started.

Want a cloud manager using BCF with free addins and ability to collaborate across your team?

If you are interested in issue tracking, BCF, and multidisciplinary coordination, then the new "BIMcollab" offering from Kubus may be worth a look:

It looks essentially like a cloud manager for BCF issues. From the marketing spiel:
  • issues directly linked to objects in your BIM together with the correct viewpoint for quick visualisation
  • all the information needed at hand to lookup, create and solve issues within your BIM tool,
  • to save all your issues in the cloud and be able to access them from anywhere at anytime.

BIMcollab centralizes issue management in the cloud, simplifies this process and offers a structured way of storing, sharing and managing issues. But more important: you have the information right where it's needed most: directly within your BIM model checker and BIM authoring tools. 

If you are already using it, feel free to comment and let us know what you think.

BIM, Revit, FM and Health

Detailed and informative article re-published on AHDC (Australian Health Design Council) website. Quote (underlining is mine):
Managing the technology 
The post-occupancy incorporation of building data into an existing system long has been a tedious and error-prone process that now can be automated via the model's geometry and data, if structured and formatted correctly. Health facility managers are seeing the value of BIM by integrating it into their existing computerized maintenance management systems (CMMS) and computer-aided facility management (CAFM) systems as well as energy or building management systems and electronic document management systems. By not limiting the application of BIM to simply a technology-to-technology interaction, the realistic outcomes that can be achieved by this type of workflow become evident. Often considered low-hanging fruit is BIM's ability to integrate into a space management system. BIM applications such as San Rafael, Calif.-based Autodesk Inc.'s Revit Architecture are capable of tracking building spaces and easily categorizing that information into departmental areas as well as floor-to-floor or building-by-building breakdowns across a larger medical campus in both graphical and schedule-based interfaces. 

In its simplest terms, a model's power to visualize space can contribute to staff and patient recruitment... BIM also can work to improve visitor wayfinding.

And the experience of Ohio State University and its 2D to 3D conversion for FM:
OSU began creating 3-D models of all the medical center buildings, helping the facilities team to understand its buildings and collaborate more effectively with the people who use them. OSU also has started using BIM in energy-use analysis and it is poised to play a key role in helping OSU to achieve its goal of being carbon neutral by 2050.

Now that the medical center has been modeled, BIM is allowing the university's facility management group to support general space reporting and to mock up spaces in greater detail for more informed decision-making processes and for future project funding. Due to the success of the initiative, OSU decided to extend the BIM program to its main campus.
"The core benefit of BIM for us comes down to being able to make better, more cost-effective decisions faster," says Joe Porostosky, senior manager of facilities information and technology services for OSU. "Ultimately, our facilities better meet the needs of users without as much time-consuming back-and-forth and expensive rework."

NWC Batch Export from Revit - multiple Revit views to multiple NWCs with one click

Have you seen the BIM One Batch NWC Exporter? Its a free little addin for Revit that allows you to select multiple views and export them to NWCs all in one go. It works well, but it doesn't have all the power of a full featured export addin (like RTV Xporter Pro - full review coming soon).

Important: during the signup process, you will have to choose a BIM One key - like a password. This is what will allow you to activate the addin manager, and use the installer. So, make sure you choose a BIM One Key before pressing 'Save' on the registration page.

Here's what the addin manager looks like:

Quick demo of using the addin in Revit 2015:

    What does BIM for MEP look like in 2014?

    Check out the survey results from Design Master Software - interesting that 2/3 using Revit over AutoCAD:

    And how does MEP industry take-up of BIM compare with what was expected in 2011?

    As with any such survey, its value must be regulated by the question:  
    "Do the survey respondents represent an accurate cross-section of the industry itself?"

    Tested: Using Able2Extract to convert PDFs to Vector information for use in CAD and BIM

    Able2Extract can export a pdf to various formats:

    In my testing, I opened a 97mb pdf file in Bluebeam and extracted one page to a separate pdf file for conversion. I opened this pdf in Able2Extract and tested exporting to DWG and DXF with various export options. My results are shown below.

    Polyline width detection: Good

    Connected segments into polyline: Good

    Hatch creation: Good, with colours when RGB ticked on export

    Good, probably best to export 1:1 then scale in AutoCAD using commands SC and ALL for selection (can also use scale export option)

    Text detection: Not good
    EDIT: Explanation "The PDF you used contains 4 embedded fonts with custom encoding (File>Properties>Fonts in Acrobat Reader). "Embedded" means that the PDF contains all necessary info to draw them correctly. But, according to PDF Standard 1.5 (, page 427: 5.8 Embedded Font Programs...

    Font programs are subject to copyright, and the copyright owner may impose conditions under which a font program can be used. These permissions are recorded either in the font program itself or as part of a separate license. A font program may allow embedding for the sole purpose of viewing and printing the document, but not for creating new or modified text using the font (in either the same document or other documents); the latter operation would require the user performing the operation to have a licensed copy of the font program, not a copy extracted from the PDF file.

    It means that we can extract from the PDF its content, but not fonts."

    Now, the real question: is it worth it? I think the ease of use is good, and the overall functionality also seems compelling for the US99.95 price tag. This is obviously a lot cheaper than buying a full standalone license of Adobe Illustrator. However, the lack of text support when converting to DWG / DXF is unfortunate. If you plan on extracting the vector information out of PDFs for tracing or use in Revit, and you don't really need the text, Able2Extract could be worth a look...

    How you can get it:
    Direct link to 7 day trial for Windows

    Main download page here and help page for DWG conversion here

    I have previously posted how to convert pdfs to vector information using free tools and using Adobe Illustrator (with video).

    I have also provided a guide on converting a raster image to vector information for use in CAD and BIM in this post:
    Raster to Vector to DXF for use in AutoCAD, Revit or Navisworks (with video)

    I loaded a 97 mb, 208 page architectural set into Able2Extract. It opened up quickly, but then it crashed before I could initiate a conversion.
