As an experienced software developer with a diverse skillset and an intricate knowledge of the 3DS Max environment, I am confident that I can deliver the efficient and lightweight script you need. With a pristine grasp on Python (the language most commonly used for 3DS Max scripting), I can ensure compatibility with the latest versions of the software while meeting your requirement to turn off snapping and angle snap during certain actions like arc rotate, pan, and zoom. I understand how these features affect the user experience and aim to improve it by developing this script.
Moreover, my past experience in developing tools for software similar to 3DS Max, as well as my strong understanding of the needs and workflows of 3DS Max users, put me in a unique position to create a script that not only meets your requirements but also enhances your overall productivity. I am focused on delivering high-quality products within tight timelines and have a proven track record of producing bug-free codes.
