I'm going to give it a closer look. Thanks. Could be very handy.
I have Solid Edge CAD to draw the results. But an excel calculations program simplifies things..

Hi, people.

Here is the new version of the tool. The four existing worksheets were cleaned out for math/formatting consistency. Some of the notation was changed, schemes were simplified, but the functionalities remain the same.

Two new worksheets, named (C/P)ComplexSolid, perform the calculations for complex solids of revolution. What kind of solids? Domes, domes with a flat top, wheels with sleek circular tires or with "fat" tires, and so on.

As explained before, use either worksheet (C)... or (P)... depending on the dimensions of the printer/paper you use. Home printer? Stick with (C). Each (C/P) pair generates different data to obtain exactly the same solids of revolution.

Please pay attention to the enclosed schemes and notes, where all parameters were described. Playing with parameters n and m leads to some crazy stuff... just try mixing n>2 with m<1 or vice-versa.

For now, I'm going to stop adding features to this tool, as the shapes are becoming really complex for such a small scale. Also, the tool is getting difficult to describe...

Regards

Joćo

Fixed some nasty errors in some formulas.
Converted all angle measurements to degrees.
