Opening marks and room numbers on the plan
Whereplan in the Drawings tab
- Doors: the item number in a circle on the side opposite the swing (GOST 21.501 allows door item numbers in circles).
- Windows: , on the outdoor side.
- Identical openings (same type and size) share one mark; in the schedule they take one row with a quantity.
- Rooms: a number in a circle above the name. On a single floor 1, 2, 3…; with several floors the number starts with the floor: 101, 102… 201.
- Numbering goes from top to bottom and from left to right and does not depend on the order in which things were drawn.
- Other tabs have no marks or numbers, so they do not get in the way.
