I don't know if tools (wrench, hammer, printer, spray can, duplicator, fillcan etc.) use raycasts but it sounds like a reasonable assumption to me. What I'm asking is a command /ttr <#> that temporarily disables the tool raycasting for the client who sent that command. This would be really useful in small scaled builds or reaching that single brick behind the desk attached to a wall.
You could simply say /ttr to toggle the raycasting until the command is inputted again or /ttr <number> to disable raycasting for the amount of seconds inputted. That way when you know you only need to reach a brick or two nearby you don't have to waste time saying /ttr again.
