CP5229: Seeing Data and More: The Analysis

Visualization Framework in the Autodesk® Revit API

CP5229

The analysis visualization framework (AVF) is a fantastic new part of the Revit API. Its primary purpose is

to be able to visualize analysis data inside of a Revit project, but you can use it for so much more than

that! You do not need to be an analysis vendor to have this be useful—you just need to want to be able to

show information graphically in Revit. For this class, it is helpful to have basic knowledge of the Revit API.

 Understand the limitations of AVF

What is the Analysis Visualization Framework (AVF)?

The Analysis Visualization Framework is a part of the Revit API devoted to being able to show

the results of technical analysis inside of the Revit environment. It was introduced in Revit 2011

and enhanced in 2012. The framework came about because the traditional workflow of looking

at analysis results (and perhaps making changes based on them) was not very good.

Traditional Workflow:

New Workflow:

There are four types of analysis display styles that can be used:

- Colored Surface

- Markers (w/ optional text values)

- Diagram (w/ optional text values) *

- Vectors (w/ optional text values) *

* only available in Revit 2012 products

Normal uses of the AVF include visualizing data like:

- Lighting

work for analysis software companies). Ideas for this include:

- Point Cloud rendering

- Point Cloud deviation from model

- Visualizing Geometry

- Temporary Vectors (curvature, grids, etc.)

- And more…

Technical Overview (Inside Revit)

Inside Revit, there are a variety of ways that you interact with AVF as a user.

Each view has a property for the default analysis display style. This controls how the data is

displayed within the view. The Analysis Display Styles are elements within the model that can

be applied to any view.
