(pronounced like the initials: en-tee-ess)

This acronym means “Not to Scale”. You will see this designation on floor plans, elevations, sections and details when the drawing creator wants to make certain that his or her intended audience – a contractor, builder, vendor, client or colleague – understands that the particular drawing or sketch is not representative of true dimensions in any measurable way. In other words, 1/4” or 1/8” doesn’t equal 1-foot and so on.
