11.0.0 for Microsoft Windows (64-bit) (July 28, 2016) ReleaseID -> " (5570737, 2016072801)

a set of 32 points :


and the instruction

hull = ConvexHullMesh[Drop[pts, -1]];

behaves normally, we can plot it like :

Show[Graphics3D[{Blue, Thick, Line[pts], Thin, Opacity[.1] }],  HighlightMesh[hull, {Style[1, {Gray}], Style[2, Opacity[0.1, Brown]]}] ]

but on my system, including the last point {8,-2,4} in the argument of ConvexHullMesh gives an immediate abort without error message.

Q1 : Does this also happen in more recent versions?
Q2 : Can this Abort be 'caught', neutralised or circumvented somehow?
It is not clear to me how AbortProtect and CheckAbort should be used in this case.

    $\begingroup$ I tested in Wolfram Engine (Jupyter Notebook) 13.3.0 for Microsoft Windows (64-bit) (June 12, 2023) and Wolfram Cloud 13.3.1 for Linux x86 (64-bit) (July 24, 2023) , neither crashed, plots looks alright. $\endgroup$

  • $\begingroup$ Any confirmations in version 11 ? Maybe the changes since version 11.0.0 are documented in a public place? Any pointers? $\endgroup$

  • $\begingroup$ I found a work-around : DelaunayMesh and BoundaryMesh both work without a problem, and equally fast. As to Q2 : AbortProtect and CheckAbort both fail to catch it. $\endgroup$
