Hello everyone.

I am working on a script that will select the edges of a mesh whose attached faces fall below a certain angle threshold. If the two faces are say, less than 10 degrees in their hinge angle, the edge will be selected.

The problem I am having is getting the angle between two faces attached to a common edge.

Heres an excerpt of the script:

////////////////////////////////////////////////

local edge_selection = #{}

local base_obj = $.baseobject

local num_edges = polyop.getNumEdges base_obj

for f = 1 to num_edges do

(

local edge_faces = polyop.getEdgeFaces base_obj f

local faces_angle = polyop.getFacesAngle edge_faces

if faces_angle < 10 do edge_selection[f] = true

)

///////////////////////////////////////////////

Of course, there is no "polyop.getFacesAngle", that returns the angle between two faces, but this illustrates what I am trying to do.

So how can I do this? Any Ideas are appreciated!

Thanks!
