Where Are Dimension Lines Typically Placed on a Construction Drawing

Dimensions are placed on the floor plan. Note that the dimension lines are drafted lighter than wall lines and are generally done as a continuous group or string of numbers along a line. The extension line begins slightly away from the object (a minimum of Vi6 inch or 1.58 mm), never touching it.

Where should dimension lines be placed?

Dimensions should be given to finished surfaces or between important center lines (not to rough surfaces) wherever possible.

How do you write dimensions in construction?

For example, a dimension of a rectangular room on a blueprint, 14′ 11″ X 13′ 10″ equates to a room size of 14 feet, 11-inches wide by 13 feet, 10-inches long. Dimensions are expressed as width by length by height or depth in three-dimensional space.
