I would like to build various coils and inductors in Sketchup to help in designing motor housing for 3D printing.
Is there any extension for Sketchup which will draw the coils and calculate their various variable values, like L = Inductance = Henry’s, R = Resistance = Ohms, C = Capacitance = Farads, Duplicate coil as 1/8th wave, 1/4 wave, 1/2 wave, V = Volts, T = Teslas, N = Turns, RPM, t = Time, A = Square Meters? There maybe some variables I didn’t mention.
There are many ways to create coils … Spirix is one of them. However, Spirix will not do any of the calculations you listed. Some of them, like the number of turns (N) or the wire diameter are things that you choose. The area (A) is also something you determine by specifying the physical geometry of the core(s). A lot also depends on the purpose of the coil … is it an electromagnet for lifting things? Or is it wound as the rotor in a motor? Or the stator? Is it AC or DC?
Can you provide a little bit more of an explanation of what you are hoping to accomplish?
[edited] In my mind, I was focused on motor coils and servos … your topic clearly says inductors
Do you have a sketch or some indication of the inductor coil you’re designing?

This is another variation of the ‘Tesla Exciter Motor’ pictured above.
In my design idea, I use permanent magnets 2" x 1/2" x 1/2" N52 Neo, the above patent was the inspiration for my design.
A basic shape for a hand crank generator, 4" radius disc 2.5" thick, a form for stator coils; Inside, 24 magnet rotor; Outside of stator, 24 magnet rotor coupled to inner rotor, where north is exterior rotor then south will be the interior rotor. The coils wrapped diametrically, one side of the coil offset in order to conform with polarity and allow for the rotor shaft.
In Tesla’s design, he hand wrapped his coils, after the construction of his rotor, around his rotor. The problem is this design isn’t modular, if you want to make changes you would have to unwrap or destroy the windings. In the learning process, you want a modular design so you can try multiple variables. There is also no idea of how design impacts Motor/Generator output. Tesla was capable of building, testing and running designs with his subconscious mind as if he had physically built it. Our version of that would be Sketchup.
And if an approximate calculation of the output can be made, since all of the variables are already placed in the design to begin with, I think that would be awesome. Volts, Amps and Watts should be enough to determine the effectiveness of the generator or motor design.
Some considerations in determining output:
Of course, some of the limitations are in determining Teslas. Maybe there is a relationship between knowns, a magnets BrMax Gauss and/or Surface Gauss to Magnetic Flux Density Gauss (Effective Gauss) as it relates to the distance between coupled magnets.
SketchUp is ideal for trying different arrangements of the possible configurations … if you’re only trying to represent an approach, you can model a wound spool very easily by creating a profile and using the Follow Me tool:
In pic 1 and 2, I’ll have to figure out how to do that with various shapes of rectangles. So your 3rd pic is like building a snowflake, using 5, 6, 8, 12, or 24 sided polygons, build one triangle first then followme. For the Exciter that would work, but for the Dynamo-Electric Machine design another method will be needed.
This is a projection of my gen design where each triangle is part of a coil, the circle is the top of the magnet rotor. I wanted to see if changing the hypotenuse would be worth while so that the coils could interleave and be modular.
