There was a demand (several independent demands) for meshing fine the "xyz data vectors" ... ! we are not talkiing about "Scatter vectors", they are are not the same monkey business !!! Here it is working fine, interpolated on the proportional parts, which proportional parts are re-injected in the interpolated export. All plotting fine, and plotting the seeked interpolated surface as demanded. The attached is saved in Mathcad 8, hoping 14 users will benefit of it. The work sheet is left as usual "modular" and I have no intention to automate it further, especially to demonstrate once more to many new users that the way to go in Mathcad is to work first "modular".
If some Mathcad chevron are willing to compact in program, welcome, I will take it... my part is done, done for the largest part of this community.
Enjoy.
