Create Swept Blend DirectShape in C++

Question: I am trying to create a swept blend geometry and assign it to a DirectShape element. The initial code threw an exception when calling the GeometryCreationUtilities CreateSweptBlendGeometry method. How can I fix this? Answer: The path parameters assume that they should be normalised or that the curve has a range of parameterisation from 0 to 1... Read more →

Revit MEP Connector Number

I answered a question in the Revit MEP forum, prompted by Robert Klempau's direct mention in the thread on connector numbers of mechanical equipment. Since it is rather technical and even includes a snippet of Revit source code, let me reiterate it here for better readability and future reference – Question: I created a mechanical exhaust fan with four connectors...

Revit Future and Saving User Configuration Settings

I encountered the need and implemented solutions to save user configuration data several times over in the past. Today, prompted by a recent query, I'll point out two of them, and some other exciting and interesting stuff as well: Anthony Hauck on Futures for Revit. The Most Popular Programming Languages 2015. Saving User Configuration Settings. Text Format Configuration File Storage and Parsing. .NET XML Configuration File Storage and Parsing. Anthony Hauck on Futures for Revit BIMThoughts is a podcast platform... Read more →

Using the Built-In Revit AcGe Functionality

Anyone who ever used the AutoCAD API for geometrical purposes must be enamoured with AcGe. On the other hand, the Revit geometry library is pretty meagre in comparison. Wouldn't it be nice to be able to use all that powerful AcGe functionality in Revit as well? Actually, if you take a look at the support DLLs included in the Revit main executable directory, AcGe is obviously present: C:\Program Files\Autodesk\Revit 2014 > dir *acge* Directory of C:\Program Files\Autodesk\Revit 2014 02/05/2013 12:52...
