I am a retired software developer. I retired at the end of 2003 and since then my computer programming activities have been for recreational purposes. I find Mathematica excellent for that.

I started using Mathematica in 1997 (Ver. 3). I am currently using Ver. 9. Although I have used Mathematica for all kinds of stuff, I use it mostly to pursue my long standing interest in Euclidean geometry, both in its classical Greek synthetic form and in its more modern analytical/transformational form.

comment Parametric Plot 3D won't show up
The form of the 1st argument is wrong for ParametricPlot3D. It should have the form {fx, fy, fz}, not {implicit-equation, fy}

You do not need SystemModeler to compile code in Mathematica.

comment How to fix the order in which text appears in an axis label (V7)
As nobody has mentioned the elephant in the room, I will. You have expressed your label text as a multiplication and Mathematica is doing its normal lexical reordering on it.
