How to say "blueprint" in Japanese

• 青写真あおじゃしんCommon
  nounThe closest equivalent covering both the literal photographic blueprint and the figurative sense of a plan or model for the future, as in a blueprint for reform.
• 図面ずめんCommon
  nounCovers drawings, plans, and blueprints in technical and construction contexts, focusing on the document itself; a natural choice when talking about architectural or engineering drawings.
  実施じっし設計せっけいとは基本設計きほんせっけいで決きまった計画けいかくを、工事こうじができる図面ずめんに書かく作業さぎょうです。↗

  Detailed design is the work of drawing up a diagram that is capable of being manufactured from the plan set in the baseline design.
• 仕様書しようしょCommon
  nounReally means a specification document detailing requirements or design; its 'blueprint' gloss fits software or product development, and it is not the word for a literal blueprint.
• 見取り図みとりずCommon
  nounPrimarily means a floor plan showing a building's layout; its 'blueprint' sense is limited to that architectural use, so it is seldom the right word outside floor-plan contexts.

Use 青写真 for literal or figurative blueprints, 図面 for technical drawings and plans, 仕様書 for specification documents, and 「見取り図」 for floor plans or building layouts.
