I have a question about creating invisible player blocking entities, such as env_physics_blocker. Here is an example of one added by Promod in L4D2.

add:
; --- block climbing truck/bus through various methods for shortcut
{
; invisible block above white truck 1
"origin" "4464 7269 -444"
"angles" "0 15 0"
"mins" "-56 -115 -204"
"boxmins" "-56 -115 -204"
"maxs" "56 115 204"
"boxmaxs" "56 115 204"
"initialstate" "1"
"BlockType" "1"
"classname" "env_physics_blocker"
}

Are there any console commands or even a temporary input value that could be set to make the block visible so that I can visually check its size and position in game and then make adjustments?
