Hi Everyone,
From the following :

How to Plot the contact-point of ΔACD (Red-Blue-Orange) and inscribed sphrere and Add that point on the Graph ?
Thanks in advance.
Best Regards.

In this answer

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.

Many Thanks for *.xmcd attached, Tokoro and Werner. 

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

Thanks again.

Best Regards.

Oh! no, Werner. I'm so sorry. You already helped me about that :

Thanks Again.

@lvl107  I could not remember, so I created the following  😉

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

Won't help as @lvl107  is using good old MC15
