Learning to create addon

 From:  Elang

Hello

I would like to create an addon (for personal project) that works similar like Max's Nuts and Bolts, only for custom souvenir box/package creation. I have very limited knowledge about JS and HTML. The only 'script' i've made are merely VBA macros for CorelDraw and Excels, so i know it won't be easy.

Yet, i would appreciate much if any of you could point me to the right direction along with the best step-by-step practice for me to achieve this goal.

Thank you very much in advance. Sincerely.


Edit: I'm sorry for forgetting to mention this: the purpose of the addon is so that for several type of boxes, I can make one type with different dimensions (height, width, and depth). It would be a quite amount of boxes so I needed to have it done just by inserting the dimensions.
