I know of ctrl+left drag. Are you in part trying to do something? What is it you want to accomplish?
thanks for pointing mistakes Mr. Steve. I wanna stop the ctrl + left drag.
Now I use the another software. It's operation similar to the CAD .
It confuse me. So, Just for protecting the confusing of operation , I wanted to stop the function.
Sorry for my poor English.
This is a common windows function, I believe. Therefore.....I suspect that the only way to get this to stop (without a major overhaul of your registry) would be to stop using CTRL when you drag your mouse with your Right Left mouse button held down.
I know that this sounds snarky.....but I don't mean it that way.
What are you trying to use CTRL Right Left drag for that is giving you problem?
Edited....see reply by me below.
OK, I just realized that you said Right drag.....and I wrote right drag....but I meant left drag.
CTRL + Right Drag doesn't copy anything inside Solidworks as far as I know. Are you sure that your mouse buttons aren't switched?
I got it. I give up stopping it and take care not to use ctrl.
It was very good for me to know I cant stop the function.
