Still at the Forge Accelerator in Rome and looking further into
the Forge Design Automation API for Revit.
Althpough it is not yet available or documented, you can still start preparing your add-in for the day when it comes
– Aspects to consider
– Accessing the Revit
– DB application add-in manifest
– Next steps...
One important step to take before trying to run your Revit API code fully automated and unattended is to ensure that it does not create or modify UI in any way. For example, you must ensure that it does not cause Revit to display any warnings. This can be achieved with a warning swallower. Let's implement one for the StairsAutomation SDK sample...

Very many thanks to the entire community for all your support, interest, comments and above all numerous contributions over the years! Today, let's pick up the recurring topic of accessing the Revit API from a modeless context...
Apparently, the Revit SDK REX Visual Studio templates are obsolete. Let's fix that problem. Also, two little notes on a C# optimisation trick for math-heavy code, and the current status of the Forge Design Automation API for Revit – Revit Structure 2019 REX Extension SDK Visual Studio Templates – Improve C# Performance Using Struct Instead of Class – Update on the Forge Design Automation API for Revit...

I am busy in the Revit API discussion forum.
However, you can check the discussions there yourself.
Here and now, I'll mention some different topics – oops, one of them is from there after all
– RST and the Structural Analysis SDK
– Determining the path of a recently exported file
– Driving NavisWorks programmatically via
– The Autodesk assistant Ava and the uncanny valley...
After the significant struggle I had to compile the initial release of the Revit 2019 SDK samples and set up RvtSamples 2019, I am happy to report that installing and compiling the Revit 2019 SDK April 27 update is a lot easier
– Downloading the April 27 SDK update
– Initial compilation – 41 warnings
– Processor architecture mismatch suppressed – 5 warnings
– Update reference to
RevitAPISteel.dll – 3 warnings
– Setting up
How to export all the Revit data to an external database?
It is very simple to extract all the parameter data.
Let's implement a solution to do so
– Existing sample implementations
– Black box input
– Choices for the output and its structure
– Retrieve parameter values from an element
– FilterCategoryRule versus category filters
– Category description extension method
– Retrieve parameter data for all elements of given categories
– External command
– Sample run results

I set up RvtSamples for the Revit 2019 SDK samples. Just like the migration to previous versions, this is not a trivial undertaking. To cut a long story short and simply share my current working RvtSamples source code for the Revit 2019 SDK, here is RvtSamples_2019.zip containing my modified files...
I already described how I installed Revit 2019, compiled the Revit 2019 SDK samples and migrated RevitLookup to the new version.

Question: How can I set the Material Render Appearance through the API?
I can see there is the
Autodesk.Revit.DB.Visual.Asset class, but how do I add to the list of
Autodesk.Revit.DB.Visual.AssetProperty objects for a new material?
Answer: The good news is that this is possible in Revit 2018.1 using the Visual Materials API.
Check out Boris Shafiro's class at AU to learn about it...

The Revit API discussion forum thread on drawing or rendering over the active view brought to my attention that an important new SDK sample created to demonstrate the use of the Revit 2018 functionality
DirectContext3D for display of externally managed 3D graphics in Revit is missing in the SDK.
I added it right here, in DuplicateGraphics.zip, and also provide an overview of the new SDK samples

Today, let's recap the Revit API discussion forum thread on moving the location of a section vie raised by Danny Bentley, BIM Structural Technician at SOM in California, since Danny very kindly created a video and GitHub repo to demonstrate and share the solution, which will certainly be of use to others as well. By the way, Danny also writes Bentley's Revit Dynamo & API blog on his personal exploration of the Revit API and Dynamo...
