Revit 2015 and Updated SDK Released

Here is just a quick note to tell you that Revit 2015 was released today, and you can now download it from the

Autodesk Revit product site.

The Revit 2015 SDK (Software Developers Kit) is also available from the
Revit developer center.

Please note that is was updated today, to replace a previous premature posting.

If you happened to download the Revit 2015 SDK already in the past few days, please replace it now with the updated version labelled April 11.

Please also note the

Revit 2015 API News – DevDays Online Recording posted
two days ago.

It provides an overview and some code samples demonstrating the new functionality.

As always, the complete description is provided in the What’s New section of the Revit API help file RevitAPI.chm, included in the SDK.

As you hopefully already noticed,

RevitLookup for Revit 2015 was
already published on GitHub and is no longer included in the Revit SDK.

I wish you a wonderful weekend, and lots of fun exploring the new features!

    Dear Ahmed,
    I assume you refer to the Visual Studio wizard to create a new Revit 2015 add-in?
    Yes, sure. Thank you for asking about it.
    I’ll do that as soon as possible. It will take a couple of days more before I can get to it, though.
    Cheers, Jeremy.

    Jeremy – did something change with Revit 2015 and CustomExporter? The line
    CustomExporter exporter = new CustomExporter(document, m_ExportContext)
    is throwing the following exception in 2015 (runs fine in Revit 2014).
    An unhandled exception of type ‘Autodesk.Revit.Exceptions.InternalException’ occurred in RevitAPI.dll
    Additional information: Failed to register a managed object for the currently active external application. A possible cause may be an inactive external application (not being invoked by Revit at present) attempting to assess the Revit API from a modeless dialog or another outside thread.

    Dear Paul,
    What context are you calling this line of code from?
    Are you within a standard Revit external command?
    Are you in some other Revit API callback or event handler method?
    If not, then you probably are not in a valid Revit API context.
    That is what the error message is trying to convey.
    Cheers, Jeremy.

    … or, as Arnošt Löbel puts it in his answer to your same question in the Revit API discussion forum thread
    http://forums.autodesk.com/t5/Revit-API/Revit-2015-exception-with-Autodesk-Revit-DB-CustomExporter/m-p/4978936
    Although it is a bit odd that the exception is an Internal exception, the reported details suggest what could be wrong. It is indeed illegal making out-of-context calls to Revit API from a modeless dialog. It has always been illegal, but Revit does not always enforces that in all possible situations. More and more checks are added to the API in each release to enforce this rule against illegal invocations of the Revit API. I believe this particular case is one of those that had been addressed in R2015.
    What I mean by “illegal” is the case when some add-in makes calls to the Revit API at times that is not within a regular and standard API context, that is a process started by Revit, such as an external command, dynamic updater, event, call-back, etc. This is the case, for example, of a modeless dialog invoking the API at any given time (i.e. outside of the contexts mentioned above). That has been always illegal and unsupported in Revit, for Revit does not support external access from multiple threads. There are only two legitimate situations in which a modeless dialog can communicate with Revit, and that is 1) during an Idling event, and 2) via an External event. Both cases are well documented and sampled in the SDK. (Look for Modeless dialog.)
    So, in your particular case of trying to register a Custom Exporter, this is what is happening: Your app implements an Export Context and instantiates it. Then it tries to invoke a custom export with the context object as an argument. Revit needs to associate the given object with the currently active (i.e. being invoked by Revit) application. However, since the call to export was called from an independent modeless dialog, there is no active application available, hence the exception.
    Cheers, Jeremy.

    i have experienced problem installing Revit SDK 2015, where a message appears saying “Installation Directory Must be on a Local Hard Drive”, and i discovered this solution, in case any one faced the same problem…
    1- Locate the Nether launcher MSI installer file that you downloaded.
    2- While holding down the Shift key on the keyboard, right-click on the Nether launcher MSI, then choose Copy As Path.
    3- Press CTRL + Q and type “CMD”, a command prompt will appear in the search result.
    4- Right-click on Command Prompt and choose Run As Administrator. This should open a command prompt window, labeled “Administrator:”.
    5- In the Command Prompt window, type msiexec /i (you need to enter a single space after “/i”).
    Right-click in the Command Prompt window, then choose Paste. This should paste the path to the MSI file that you copied in Step 2 above.
    Press Enter to run the command.

    Dear Moustafa,
    Thank you for reporting this and suggesting a solution.
    Alternatively, you could simply install to the local hard drive and move the resulting folder anywhere you like afterwards.
    Cheers, Jeremy.

    I guess we all did anyway, although it was an illegal call. It will cost thousands of dollars to develop new behaviors, just to make my beloved tools work as they did in Revit 2013. Lets get it on.

    Dear Matthias,
    Very sorry to hear that it is causing problems for you.
    On the other hand, it is good news that your programmers are so well paid, and that you can afford such qualified labour!
    Congratulations on that!
    Cheers, Jeremy.

    public Pipe CreateNewPipe(Document document, ElementId systemTypeId, ElementId levelId)
    in 2015 pipe.create(..) need ElementId levelId, in the new drawing how to get the ElementId levelId

    Dear Derek,
    You can either take the level id from an existing element, e.g. another pipe, determine a suitable level from the elevation Z value, or anywhere else you like.
    It may also be possible to specify null or an invalid level id.
    Please let us know how you end up solving it.
    Thank you!
    Cheers, Jeremy.

    since this is the new drawing,so there is no pipe object in the drawing. So I cannot determine it from the existing. If I put is as null. Error will show up when I try to pipe.create(..)
    Is there anyway I can set it up first or set up a suitable level from the elevation Z value?!
    If yes, how to set up this Z value?!

    hello Jeremy,
    I am facing below error
    “Failed to register a managed object for the currently active external application. A possible cause may be an inactive external application (not being invoked by Revit at present) attempting to assess the Revit API from a modeless dialog or another outside thread.”
    In my solution I have created Dockpanel using WPF. I am registering this DockPanel in Idling event of UIControlledApplication, while registering I have passed UIApplication object to MainPage(UIApplication).
    Inside dockpanel I have loaded some Families and I am trying to load those family using UIAPp.ActiveUIDocument.Document.LoadFamily(filePath);
    while doing this I got above mentioned error, could you please suggest.

    Dear Atul,
    I suggest you start again from scratch and base your add-in on a sample that works.
    Cheers, Jeremy.

    hi jeremy,
    Can you provide any document which explains the Avoid Obstruction Revit Macro in detail step by step.
    I am not able to understand the how the program is written logic wise.
    It will be very helpful if we understand the logic behind the program.As we are trying to use write a new code about pipes.It will be very helpful.

    Dear Madhu,
    I have not the slightest idea what macro you are talking about, so I cannot help with that.
    Are you aware of the AvoidObstruction SDK sample? That is of course not a macro, but an add-in.
    It is discussed in numerous earlier posts on The Building Coder and its implementation is explained in its readme file ReadMe_AvoidObstruction.rtf.
    Cheers, Jeremy.
