Slope analysis in Grasshopper

[chanley (Chris Hanley)]

There are some discussions/examples of approaches here: (search for slope analysis will certainly turn up some more).

Grasshopper Terrain Slope in Degrees

In addition to the suggestions already given, In order to get “percent” VS “degree” you just need to do a little math in between. [SlopeAnalysis-PercentAndDegree] This example uses one custom component to explode the mesh. There are a few others around. Also, depending on the types of surfaces/meshes you are working with, I have found this to help speed things up a bit. Explode the mesh, decompose and measure against another vector(as described in other examples), then average them togethe…
