I am interested in working out terms to use for following things
If you draw drawings based on lines or segments, and don't worry about the areas they enclose just the lines themselves and how they glance each other. Currently I would say that this kind of drawing has a priority for lines. Or line priority.
If you draw with enclosed areas and close all your shapes then I call that you have you have a area or rather shape priority.
Image 1: Difference in thinking
So for example Illustrator is built with shape priority in mind. If for we take arbitrary feature like pathfinder it is unable to delete line segments. But perfectly capable of building enclosed areas. It is not until shape builder that you can consider deleting line segments, even then only if there isn't a area to choose over the line segment.
Now as a counter example. Engineering applications and documentation often are built on line priority. As far as explanations go that's all fine and dandy.
However does anybody know if the names line priority and area/shape priority have some known terms in well known literature.
