Dynamo view analysis | parametricmonkey

In this previous tutorial I demonstrated how to undertake various view analyses in Grasshopper with Ladybug. Some of these analyses can also now be performed in Revit within Dynamo. This tutorial will show you how to create a 2D isovist by creating filled regions and if desired, assigning the fitness of the view to a room parameter in which it is associated.

 

One of the simplest methodologies for undertaking a view analysis is to use an isovist. An isovist is the volume of space visible from a given point in space. Isovists are naturally three-dimensional, but they may also be studied in two-dimensions. Back in June, Nate Miller updated his LunchBox Dynamo Package to include a new isovist node, ‘Intersection.CreateIsovist’. Furthermore, with the release of Dynamo 1.2.0, there is now the ability to create filled regions with the ‘FilledRegion.ByCurves’ node. This means that not only can isovists be analysed but they can be visualised and documented within a Revit…
