Hi, I don’t think you will get any advice here on autolisp. I am not sure if reddit has subs that might cater for that, it may be that you have to go to an autocad specific forum to get what you need.

Is there something specific that people may use emacs in that situation?

I imagine it is as easy to interface with as any other piece of software that people need to use assisted. If your question is could it be better than other pieces of software I suppose it could be made to be so.

I use a corne for desktop and mobile. Mine is usb but you can get bt. Diy or prebuilt but it has a reasonable form factor.
