A document was recently released that essentially describes differences in the way that Tekla and RST respond to changes in a linked architectural model. This document doesn’t really take into account the other benefits of working in a completely Revit environment – not having to convert to and from IFC, tagging through links, scheduling, bidirectionality, and so on (I don’t feel a need to keep listing reasons 🙂
There are quite a few interesting ways to animate a Revit model these days. You can use Image-O-Matic, things like Level Displacer, and there is also an interesting SDK sample for animating structural elements.
From The Building Coder: One of the very visually impressive Revit 2014 API samples is the DisplacementElementAnimation application. It automatically animates groups of structural building members in any Revit BIM, proceeding sequentially from bottom level to top. It creates and executes an animation of the model by disassembling and then reassembling it from the ground up. The members are sorted into groups based on category and level and displaced from their actual position. Each group is then animated using the Idling event until the model is reassembled. It is an external application, so it is not automatically made available by installing RvtSamples, which just provides access to the external command SDK samples.
To get this running, you will need to install the 2014 SDK, open the applicable CS project, add the Reference Paths, Build it, add the dll and create the necessary .addin file. However, if you want this type of animation – it will probably be worth it!

We are seeing this error on a received Structural model: Analytical model edge cannot have a length of zero (0)
Revit does not offer a solution – you can’t Delete Checked, and you can’t press OK. It just keeps coming back.
Unticking the “Structural” instance parameter for the hosting floor will work (it just gets rid of the problematic Analytical Floor), even if unticking the “Enable Analytical Model” box in the Properties Palette won’t…
However, I think this is a bug or at least an undocumented problem that needs a better fix.
“quickly connect … Revit models to the GRAITEC Advance suite and then optimize the design of their structures in accordance with North American and Eurocode standards and produce effective and error-free general arrangement drawings, fabrication drawings, BOMs, NC files for both steel and concrete structures.Read more. GRAITEC BIM Connect is available on Autodesk Exchange for Autodesk Revit.”
There is a extensive list of whitepapers for Revit Structure over at this link. A few particular items of interest are shown below:
Coordination between Revit Structure and Revit Architecture Structural engineers who use Revit Structure software can coordinate their work with architects using Revit Architecture software. This paper examines how building information is shared between Revit Structure and Revit Architecture users.
Maintaining BIM Integrity in the Structural Engineering OfficeA key benefit of building information modeling (BIM) is the ability to share digital model data among members of the design team. This paper examines the role of the structural engineer in the BIM process and explains how the integrity of the building model is maintained during the structural engineering process.
