Construction Lines and layer organisation

I want to understand construction lines. Have started working with layer
naming quite recently.  Should they typically be placed on the dimension
layer, or is it better to create a separate construction layer? How does
LibreCAD identify or determine whether a line is a construction line?

Although I read about the construction view-hide icon # on each layer.
Thusly I do not knew how things work and what LibreCAD acts upon
when enabling construction line view on some specific layer.
