Errors whilst trying simple Delaunay and Convex Hulls tests

Geometry

Hi all,

I’m trying to do some really simple tests/ visualisations with Convex Hulls, Delaunay Triangulation and Voronoi Diagrams, but for some reason my Convex Hull and Delaunay Triangulation nodes don’t work with unclear errors:

Delaunay error:

Node Name: Delaunay.ByPoints
Package: Geometry.Tessellation.Delaunay.Actions
Dynamo Version: 2.19.3.6394
Host: 
Messages: Delaunay.ByPoints operation failed. 
The input data is degenerate. It appears to exist in 4 dimensions, but it is a 3 dimensional set (i.e. the point of collinear, coplanar, or co-hyperplanar.)
State: Warning

Convex Hull error:

Node Name: ConvexHull.ByPoints
Package: Geometry.Tessellation.ConvexHull.Actions
Dynamo Version: 2.19.3.6394
Host: 
Messages: ConvexHull.ByPoints operation failed. 
Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index
State: Warning

Both of these require the points be non-planar if memory serves. Try moving one of the points in the Z axis or add one more point with a change in the Z.
