I showed how to calculate all four points of contact (in German: "Berührpunkt").

To get the point you are looking for you would call "Berührpunkt(A,C,D,M.i)"

The array "Berühr" calculates all four and creates a structure which can be easily plotted.

Since I forgot to attach the worksheet at the time, I have now done so now.

    @Werner_E , if you don't mind, I still have another related query about "create a program". Otherwise, I'll start a new Topic.

    Converted to Prime 8 the Werner_E's plot. Just after the conversion, the plot shows axis line back side of tetrahedron.
