Asuming a cube, having 8 points, how do I turn the selected points into a triangular faced chamfer ?
Hi -
Create one of the planes at a point, and, assuming a cube, polar array that, then mirror. Use these to split the cube. Then cap.

Thank you for the explanation, I am quite lost at create one of the planes, could you please elaborate
Decide what distance, d, from the corner you want the cube edge to be cut.
Draw a sphere centred on the corner with radius d.
Create the intersection between cube and sphere (_Intersect).
Delete sphere.
Create a cutting plane for the cube (_CutPlane), using the three point option and selecting the ends of the intersection as the three points.
Delete intersection curve.

Fun, and perhaps slightly quicker, alternative way to create the facets:
Place a point, a, at the centre of the cube. Place another, b, on one of the edges where you want the facet to cut it.
Draw a sphere centred on point a and with radius set at point b.
Create the intersection of cube and sphere.
Delete sphere.
Select all 8 intersections and use _Rebuild to set points to 3 and degree to 1.
With the now straightened curves still selected, _Trim the corners off the cube, then delete the curves.
_Cap the cube.

If you are up for using a Python script, then the script attached follows the process outlined in @jeremy5 's first response.

The Rhino Polyhedra Plug-in (access through PackageManager) can make a ‘truncated cube’, but looks like the size of the triangular faces is non-adjustable.

Just for fun, here is a variable truncated cube in GH…
