I am a newbie of metapost. Please forgive my question if it is too simple.
- Can we define a path for two parallel lines？ As daleif explained below, the answer is no since it is not a connected entity.
- Can we define a path for a connected entity that cannot be drawn in
one stroke? For example, the picture below. Now I can't build one path for it.
I regard path as a block (including many items) and you can do action on the path thus working on all the items in the path. For example, for the above image, if it can be defined as a path
grid, we can define grid linetype for all lines by
draw grid dashed dashpattern(on 1bp off 2bp on 10bp off 2bp);. We can also do transformation on path.
