As @GavinNicholls wrote you can use convex hull also you can use Alpha shape as shown in the below post

Alpha Shape proplem (Draw outer line around the outside point Cloud at the same plane by ignoring any points that would fall inside.)

Draw outer line around the outside points by ignoring any points that would fall inside.

Concave Hull (Alpha Shape) from list of points with Python?

I cleaned up the code a bit: import clr clr.AddReference('ProtoGeometry') from Autodesk.DesignScript.Geometry import Line from math import sqrt, hypot points, alpha = IN OUT = [] pLen = len(points) alpha2 = alpha * alpha if pLen < 2: raise Exception('AlphaShape needs at least 2 points') for i, p in enumerate(points): for j in xrange(i+1, pLen): if p.IsAlmostEqualTo(points[j]): raise Exception('AlphaShape needs pairwise distinct points') dist = hypot(p.…
