Dimension

1. Hierarchical dimension placement
2. Dimension lines are placed hierarchically in 2 to 3 levels of overall dimension; wall dimension; and opening dimension. Overall dimensions are outermost dimension lines, and measure from outside edge to outside edge. Wall dimensions are the next dimension lines towards the plan, showing exterior wall or interior partition locations
3. The closest dimension lines to the plan, opening dimensions, indicate window, door, and other opening locations. These three hierarchical dimension lines are placed 1/2" from each other. The innermost dimension, the opening dimension, is 1” to 1-1/2” away from the plan, never touching it.
