Marco -- EXCELLENT !!! -- I thank you very much !!!! (Also, I attempted to send u a return 'e-mail' coupla days ago
to thank you for your FORMER help - here is/was content: "[[Marco -- You really didn't need to go thru all that just to get me a solution !!! However, thank you very much. Indeed, these 2 (ContourPlot3D; ParametricPlot3D) are very good
'substitutes' for Sphere command. I use both [and others] in my 2.2. I just today downloaded a 'trial version' of 10.1; also went online & used their 'cloud' to run a few 'Sphere' generations. How is COLOR of spheres controlled; in my 2.2, color is random when generating multiple random plots (I believe; maybe I haven't added sufficient/correct commands. i.e. - if I evaluate: rcoord := {Random[ ], Random[ ], Random[ ]} ; and then: Show[Graphics3D[ Table[Cuboid[20rcoord], {25}] ]] or Show[Graphics3D[ Table[Sphere[10 rcoord], {20}] ]] using 10.1, is there a 'color' command to insert either in the 'rcoord' statement or within the NUMBER of geometric figures to show - possibly - Show[Graphics3D[ Table[Sphere[10 rcoord], {20; color -> Random}] ]] ??? )
Again, THX !!!! Sorry to bother ]]" ). --- have since found the many 'color' options.
Also, I have been going thru the documentation and finding many 'features' and solving most of my own issues w/Rev 10.1.
What I haven't found [yet] is a good tutorial on ' where/how to properly insert/use some/all of these formatting commands/functions within the syntax of the general math function itself ' - i.e. - Does 'Boxed -> True' (or other formatting) require certain LOCATION in the overall statement? I seem to recall an error message stating '... X needs to be placed no more than 3 commands from end...' --- maybe I'm just getting senile! Having used 2.2 since YOU were in diapers (Ha Ha), I find 10.1 incredibly rich in content/capability; but of course, in this business, nothing is free !!! With increased complexity/richness comes concomitant increase in degrees of freedom of syntax ( I think).
Thanks again for assistance. BTW - u work at Wolfram ?? Where do u find time to solve problems submitted by idiots like me ????
