This may increasingly look like a minor element, however in freehand drawing—from direct remark—how traces meet, or not meet, can convey a lot in regards to the nature of the kinds we’re capturing.

Take, for instance, the drawings above, the place assembly traces at corners can convey a crispness of planes and edges of volumes.
