Backup Your Screencast Data Automatically And Access the Video Files For Offline Use

Autodesk Screencast is a great screen recording tool. However, it is very tied to the cloud. What if you just want to grab the screen capture video file to put it onto your company LAN or insert it into a presentation?

The short story:
  1. Set the Screencast folder location
  2. Setup a RealTimeSync to a 'Screencast backup' folder
  3. Run the RealTimeSync on startup
  4. When you want the source video file, navigate into the backup folder, find the Screencast you want and look for a package.zip. Inside here is the webm file you can copy out and play with VLC or some other player.

 You could also use a video converter to convert the webm file to an mp4 or some other format that you could embed into PowerPoint etc.

    Dynamo 1.0.0 Stable Build Now Available

    Quite a momentous day!

    You can download it at:

    (or you can wait for the auto update :)

    ### 1.0.0 ###

    - API Stabilization:  1.0.0 is a commitment to stable code that allows for smoother and more reliable movements from one version to another.  To more clearly express this, we have been moving to “semantic versioning” to illustrate the nature of changes in each release. We will be using the fairly standard version naming with an x.y.z system, where x incrementing represents breaks to the API (requiring developer refactors), y indicates changes that are still backwards compatible, and z are smaller bug fixes.  Package creators and maintainers are encouraged to assess changes to the previous code, which can be found here 


    - Graphics performance enhancements:  see this post for details 
    - Documentation: Along with new sections of the DynamoPrimer (http://DynamoPrimer.com), we have started an online documentation of the Dynamo API with a searchable index of public API calls for core functionality. This will be expanded to include regular nodes and Revit functionality.  http://dynamods.github.io/DynamoAPI/
    - Licensing:  Dynamo Studio is now using a new version of the Autodesk installer that allows for easier access to network and token flex licensing tools
    - Install:  we have created a separate installation for "core" Dynamo functionality, those tools used by all implementations of Dynamo, and Revit, and Studio installations.  This allows for the sharing of a common core of Dynamo code and packages.
    - List Management:  Changes to "replication" or automated matching of different data streams in nodes and Code Block nodes eliminates the need for List.Map and List.Combine in many situations
    - Send to Web: formerly known as Share Workspace, we have improved the ability to view and interact with Dynamo online with Customizers
    - File Export:  Users can now author DWG files in the Translation section of Dynamo Studio.
    - Direct Shape:  Dynamo in Revit 2017 can now take advantage of faster and more sophisticated direct shape creation.  In most cases, solid and surface geometry can be sent directly into the Revit environment as smooth (rather than tesselated) surfaces and solids, categorized to whatever is needed.  In the cases where a smooth element cannot be created, a tesselated (mesh) object is created, as was the case previously.

    Bug Fixes
    - An extensive list can be found here: http://dynamobim.org/incoming-bug-fixes-for-dynamo-1-0-0

    Good Things and Not So Good Things About Revit 2017

    (insert obligatory Revit 2017 blog post here...)

    The annual Revit release schedule can become very tiring. Also challenging is the fact that you will probably not start running real, big, live Revit 2017 projects for around 6 months, so all of this new features noise will be a distant memory by then. However, it is good to be aware of the new abilities in the software, so that you can (possibly) stop using outdated workarounds and start using the software in the way Revit 2017 Wants.

    By now, we should all be focusing on getting more useful data into our models. In accord with that aim, these are my top 3 new features:
    1) Keynote Legends are better - Use Keynotes!
    When a keynote legend is set to By Sheet, Revit takes into account whether a keynote is visible in the view as a result of View Range settings, Design Option settings, or Depth Clipping/Far Clipping settings.

    2) Combined parameters in Schedules - Use the Data you Have!
    Combine parameters in a schedule to display the values in a single cell. You can specify a prefix, suffix, sample value, and separator to display with each parameter. See Combine Parameters in a Schedule.

    3) Schedule view templates - Templates are Good Revit
    View templates for schedules and assembly views: To simplify the reuse of schedules, create a schedule view template. Schedule view templates include parameters for Fields, Filter, Sorting/Grouping, Formatting, Appearance, and Phase Filter. If the model contains RVT links or design options, Visibility/Graphics Overrides parameters are also available. See About Schedule View Templates and Create Assembly Views and Sheets.

    Free Revit Families and Sample Downloads from What Revit Wants

    Over the years I have used many workarounds to get things done in Revit, and usually I post about how to do it, and sometimes I offer a family or RVT download too. However, some of these resources are now deeply buried in the blog history (hard to believe I've been doing this since 2008!)

    With that in mind, I have created this post to share some of the more useful and interesting downloads with you... again :) I'll try to keep this page updated with the current set of What Revit Wants freebies and downloads.

    I hope you enjoy the huge range of samples, workarounds, hacks and scripts linked below. Typically the title of the download is the link to the family, and the next line is the source post:

    Feel free to comment to let me know if these are useful, or if they are not :) In some cases, Revit has 'caught up' and the older workarounds are no longer necessary.

    Also, for resources I create and share I will now use the tag WRWdownloads for easy discoverability.

    Override Cut Lineweight of Flat Pipes when Cut Perpendicular in a Revit View

    If you cut a sloping pipe in Revit, you can override the lineweight using Linework tool (or Visibility / Graphics) easily, because you are dealing with a model element. However, if you cut a 'flat' or horizontal pipe in a Section or Elevation, Revit assumes you want the nice system-related cut symbol for that Pipe and you can't easily override the Cut Lineweight with a Linework tool.

    What you need to do is turn off that default Symbol in Visibility / Graphics, and then you can successfully override the Cut representation.You may find that by turning off the Drop or Rise option, the symbol isn't shown and the Linework tool will be active for the cut lines of flat pipes:

    Dynamo and Revit 2017

    For a while here on What Revit Wants, I was a bit worried I was writing about Dynamo too much... "Hey, Dynamo isn't Revit, its just an addin!"

    But guess what?

    Now Dynamo is Revit, its right there on the Visual Programming panel, Manage Ribbon.

    If you were running Dynamo 0.9.2 prior to installing Revit 2017 (perhaps as part of Building Design Suite Ultimate 2017), you won't immediately see Dynamo on the Manage Ribbon. After installing Revit 2017, re-run the Dynamo install package, and ensure that Revit 2017 is selected:

    Next time you launch Revit 2017, Dynamo should be in its rightful place, right there on the Manage ribbon, ready for you to jump in and start winning.

    Convert BCF to PDF with this Free Utility

    The BIM Collaboration Format is getting more popular and more widely supported as the months go by. I was interested to find to this little command line utility that quickly creates a PDF file from a BCFzip. It can batch process multiple BCF files and it outputs a relatively clean PDF with the image and issue name.

    What is it? From Sourceforge:
    This project provides conversion/rendering of a BIM Collaboration Format (BCFZIP) file exported from Tekla BIMSight and similar applications to a PDF report. It can be useful in several ways, such as:
    1) sending someone a PDF report instead of BCF file.
    2) Print a hard copy of BCF report for signoff
    3) Review BCF content quickly without installing or launching any BIM software

    Command line usage:

    PDF output looks like this, 1 issue per page:

    Download and main page at:
    BCF2PDF download | SourceForge.net

    Instructions, showing you can also use drag-and-drop for multiple BCFs:
    1. Download the file BCF2PDF.rar from Source Forge and place in a folder.
    2. Export one or more .bcfzip files from Tekla BIMSight or other similar applications.
    3. Drag the .bcfzip files and drop onto the icon of BCF2PDF.exe executable.
    4. One or more PDF reports will be created in the same folder as the source .bcfzip files.

    The Best Just Got Better... A Review of Lumion 6.3

    I love unique tools. In the BIM world, we are presented with a wide array of visualization software, each supposedly better than the last. But I am interested in something that has real power, that is truly unique, something that can give me and my work an edge over the competition. And Lumion is one of those unique, powerful tools.

    It is fast, easy to use, and the visuals are so immediately pleasing. In just a few minutes, you can go from a Revit model with links and topography, into a beautiful 3D environment. There is a huge library of People, Trees and Vehicles included with Lumion that can be placed immediately into the scene. The more time you spend working up the scene, the better and more realistic it looks.

    During the preparation of this article, Lumion 6.3 was released. I have made an effort to discuss key points from that new release here. The big new feature of 6.3 is that Lumion now supports Samsung Gear VR and Oculus Rift! Find out more at this link.

    So that's the quick summary, but how does Lumion integrate with a real Revit environment? What considerations are there when working on federated models? What tips and tricks did I discover along the way?  Read on to find out...

    This review is divided into the following major sections:
    • Real World Use
    • Summary of New Features
    • Basic Use
    • Specific Tips and Workflows
    • Learn More
    Real World Use
    If you want a quick overview of what can be achieved, check out this Showcase page on the Lumion website.

    Test System
    Lumion uses a live rendering engine, so effects and animations all essentially occur in real time. This means that you need a decent computer, with a good graphics card, if you want to get the most out of Lumion. I tested Lumion on my 2 year old workstation, with these specs:
    • Intel Core i7-4930K (6 cores, 12 HyperThreaded) CPU
    • 64gb RAM
    • NVIDIA Quadro K4000, 3gb GDDR5, driver 353.62
    • Samsung SSD 840 EVO 500GB + 3tb secondary drive
    The above specs were more than acceptable for my use, but you may find that a newer gaming graphics card would compensate for a current mid-range system with less RAM.

    From Revit
    Lumion imports a number of native 3D formats, including FBX and DWG. However, there is also a Revit export addin (called the Revit to Lumion Bridge) available that gives better optimization to the exported 3D data. I found the addin very quick to use, even on a large site with multiple buildings. After exporting into one container DAE file, you then use the Import option in Lumion to bring that model into the current Scene.

    If you have some well developed Topography in Revit already, you probably just want to 'feather' the edges of the Lumion Terrain. A Lumion scene is made up of a number of parts, but it always has a base Lumion land surface (that could be flat or modelled to really any land form), and then you typically have a model imported from some other software, following which you would usually add content and entourage to the scene, such as People, Trees and Vehicles.

    After you have imported a model and integrated into it into the scene, I feel that it is very rewarding to add some content to the scene immediately. The large library of content allows you to quickly get a 'look and feel' happening that will help drive the artistic process from this point forward.

    I say "artistic process", because that is actually how Lumion makes me feel - like an artist, not like a boring BIM technician. And that is a good thing! Rather than wrestling with the usual mind-draining, complicated Revit modelling tasks, Lumion is like a breath of fresh air. The payoff is immediate, unlike some other rendering workflows that often require many hours of material mapping before anything remotely aesthetic can be generated.

    From Navisworks via FBX
    I thought it might be interesting to try and play with a relatively basic building form or mass, and see how Lumion can make even basic geometry look quite impressive. To start with, I used a model in Navisworks of Room spaces (which were exported from Revit via NWC). Then I exported these Room masses from Navisworks to FBX.

    The resulting FBX file was 167mb.

    I opted to try the Mountains in Spring scene template. The water in Lumion is nothing short of beautiful. Its almost too good to try and demonstrate with a screen capture, but I'm going to try anyway... Keep in mind that as you navigate in Lumion, the water is moving and rippling and lapping away at the smooth stones. Amazing!

    In just a few minutes, I had trees, a power boat, a sunbaking man, and even a fish, horse, and offshore wind turnbine placed in the scene. Lumion has this potential for rapid, beautiful scene development that is unparalleled in my experience.

    Modifying Placed Objects
    The Lumion interface is clean and uncluttered. Sometimes, you will 'discover' how something works in Lumion, and it will just make sense. For example, if you are trying to move a Person and can't select them, keep in mind that you should pick the object Category from the bottom-left corner of the window, and then you will be able to modify objects of that Category.

    Modifying the Environment
    I was impressed with the fact that the sun height is extremely easy to modify, to get things looking just right, as the screencast below shows:

    Key points to remember
    Some of the features added in Lumion 6.0.1 and 6.3 are focused a lot on improving the image quality, which means you are getting the very best output from the scene creation work that you undertake. Another key differentiating feature of Lumion is the overall ease-of-use. It does not feel like a complicated piece of software, and it allows you to get up and running quickly. Then, as you learn more about Lumion, you can progressively discover the additional features that are just below the surface of the main user interface.

      Summary of New Features
      Lumion 6.3 now supports the rendering of VR panoramas for Gear VR and Oculus, and it is very simple to use. First, press the MyLumion button, Set a Viewpoint, then click Render VR Panorama:

      For Oculus Rift, choose LumionVR to render an LVR file:

      You can watch as the renderer works its way through the left eye and right eye:

      Finally, open that file in the LumionVR viewer (included with your Lumion 6.3 installation) and interact with the scene using the Oculus Rift.

      There are also some key aesthetic additions that became available during the releases of Lumion 6 through 6.3, and the imagery below gives you an idea of what each effect can accomplish once applied to your projects.

      Hyperlight 2


      SpeedRay Reflections

      Basic Use
      Download and Installation details
      Download size: 6.26gb
      Installed size:  14.6gb

      First Launch
      On first launch, Lumion will benchmark your system so that it can self-configure the best performance settings for your particular hardware.

      After the benchmark you will be presented with this Start screen, which will allow you to quickly create projects for a variety of different scenes and enviroments:

      Specific Tips and Workflows
      We all work in different ways. And we all have our own artistic style. So when considering how to best integrate Lumion with an existing design and presentation workflows, there will obviously be some variations. But essentially, you will take models from a content creation suite (such as Revit) into Lumion, and then perform various tasks such as site modelling and adding entourage, after which you will tune various presentation style settings and export to a video or still image.

      You can read a real world example of how UK architectural practice Lovelock Mitchell has made Lumion a part of their day-to-day design pipeline at this link. I could certainly identify with this comment that Michael Chevasco made in the article:
      "If you like the visualization side of architecture like I do, then you might find experimenting with Lumion artistically rewarding, for example, positioning the sun just right to create a certain mood, or the getting the wind to blow through the grass in a scene. I enjoy those things and Lumion makes it easy."

      How to Use Lumion with Revit
      Latest Revit exporters are available here:
      Export Revit models to Lumion - Revit to Lumion Bridge

      To install the exporter addin:
      1. Run applicable installer, such as RevitToLumionBridge_Revit2015.exe
      2. Restart Revit
      3. The addin will now be available on the Add-Ins ribbon
      Export and Import to Lumion:
      1. Open a Revit project
      2. Go to a 3D view
      3. Run the Exporter
      4. Go to Lumion
      5. New Scene based on Template of your choice (I chose 'Hills')
      6. Import using this button:
      7. Name your import and tick the box

        Tip: Make landscape flat:
        You may want to 'flatten' an existing landscape prior to matching Revit topography with Lumion terrain. The image below shows which button to use:

        Use large terrain brush to quickly match Lumion surface with Revit topography:

        More information on terrain material and feathering here

        Here is a List of File types that can be directly imported to Lumion:

        Performance Notes
        • The Revit exporter was very fast, taking about 300mb of Revit data to a 230mb Collada file in 90 seconds
        • Saving in Lumion is very quick and unobtrusive
        Saving Viewpoints
        You can use the Camera tool to Store a Camera, and return to that same position later:

        Basic Intro to Dynamo Presentation

        I put this presentation together about 6 months ago, which is forever in DynamoWorld. But I thought I'd share it anyway, just as a general and basic introduction to Dynamo.

        View and Download

        Using a Single Parameter Value to Drive Visibility States of Many Elements in Many Family Instances

        Using some Visibility parameters and a simple formula structure, you can use a Revit family to store a collection elements and then selectively show them by using a single lookup value. This allows you to drive many visibility states (programmatically) through the modification of a single instance parameter value.

        In the case below, I created a Annotation family and multiple Yes/No visibility parameters, which I applied to Lines:

        Then, I make a VisibilityEnum integer parameter, and set the Yes/No parameter formulas to a given integer:

        You can also use Greater Than and other operators to show items that are visible across multiple visibility states:

        In the project environment, you only need to set one instance parameter to change visibility states:

        Finally, with some inventive use of Excel and Dynamo, you can drive this visibility parameter programmatically, even mapping the visibility state to the owner view of the family instance in Revit:
