Accessing privelage / public methods from object instance about openjscad.org

[MauricevanLeeuwen]

var involuteGear = new involuteGear(params);
involuteGear.pitchRadius = 15;

This will change the pitchRadius property, but nothing more than that. Remember that the other properties, and also the resulting polygons, don't change when you change the pitchRadius:

var foo = 5;
var bar = foo * 5;
foo = 10;
console.log(bar); // prints 25

The current gear example code isn't well suited for what you want. You need to rebuild the complete model if you change a thing. So when you update something:

var changedInvoluteGear = new involuteGear(changedParams); 

I haven't looked much into OpenJSCad yet, but I don't believe there's another way to deal with changing parameters than with this.

If you want to change the way involuteGear works from time to time, you may do some prototypal inheritance

Thanks for the feedback! I only need the the number of teeth, thickness, and center hole info for each gear. So would it be appropriate to separate these functions out as a prototype method and process them first?

I can think of two options...

1. Move the variables outside the function. This makes the variables "global" and can be accessed easily.
2. Change the function to set a property on given parameter, i.e. return the calculated value as a property
   So, you'll have to change the code.
