Introducing VASA, a tool for Voxel-based Architectural Space Analysis

I’ve been hinting about this for a few weeks now, but today is (very excitingly) the day for the big unveiling. My colleague Rhys Goldstein has been working his magic, once again, taking the algorithms he developed for the 2D Space Analysis package and applying them to 3-space. If you were impressed by Space Analysis, what we’re showing now may just knock your socks off.

The new package is called VASA, which stands for Voxel-based Architectural Space Analysis. It’s available today for download from the Dynamo Package Manager.

It’s worth unpacking a couple of terms, here: voxel-based means VASA breaks the world up into cubes of a certain size, in much the way Minecraft does. It can do so by reading from a mesh – it can use STL files or meshes generated from Revit geometry, for instance – and checking whether any of the polygons clash with any of the voxels (at which point the voxel is marked as being “on”). It then allows you to perform a number of analyses on this 3D…
