Hi guys;

I was trying to de-pasta my refinery last night and had issues determining which direction my porpoising pipes were flowing. Would it be possible to have (by preference) a dynamic marker on the underground pipes showing flow direction; failing that a decal/arrow version we could build to put markers occasionally.

I did a quick check in mods and topics but nothing came up for such a light weight option.

Regards

Because you have the pipe-windows for that.
Just leave enough space so that the windows could be built.

Moved to implemented.
