Plan with a drain and a master drain
A planimetric sketch labelled a, annotated with a drain and a master drain (scolatoio maestro)
A planimetric drawing built up from many short hatched strokes lays out a plan labelled a, annotated with a 'drain' and a 'master drain' (scolatoio maestro) that carry water off it. The design concerns the drainage of a laid-out structure or site. Further untranscribed notes appear in the left margin and along the lower edge of the sheet.

The sheet is filled with a planimetric layout, drawn in short hatched strokes and keyed to the point a, showing the arrangement of the works in plan.
A drain and a master drain
The plan is annotated with a 'drain' and a 'master drain,' identifying the channels that collect and carry the water away from the layout.
