Stripped version help

[kopsinnovaties]

What a fantastic version, I would like to integrate a part of this into my app. The only thing I really need is the "free" drawing (initHistory("boot"), or in other words; starting with a blank stage. Since my main focus is on drawing floor plans, adding elements (except perhaps doors and windows) is not necessary. When the page is opened (in my case, it will be a modal with 90% width), drawing should be possible immediately. Hence my question; what components and functions are minimally required to achieve this? And; what divs and svgs are minimally needed? I am willing to pay for such a "minimal" version (of course, depending on the costs). I can figure some things out myself, but this takes time, I assume you already have the code much clearer in view. Looking forward to hearing from you! Regards, Sake
