In Adobe you can draw on layers. These can be shown and hide as desired.
For example, I only want to have the outer contours on one layer, only the filling on another, other layers contain symbols...
In addition, individual passages should be shown and hidden separately in addition to the details on the layers.
There are worksheets and drawings. The drawings work like the layers, but cannot be hidden? What are the worksheets for?
What is an practical workflow to draw a cave with the intention to begin with no details and add them later?
