The instrument used for reducing and enlarging a plan is Pantograph.
Explanation:
- Pantographs are instruments which are used for copying and enlarging plans, handwriting, and drawings.
- They have mechanical links that are connected in a way so that there is free movement of one pen for tracing an image, and it produces identical movements in a second pen.
- There are various types of pantographs used for different kinds of duplication in the fields of sculpture, engraving, and minting.
- There are extension arms in the instrument which work mechanically for tracing drawing or a plan with scissor mechanisms like an accordion.
- The pantographs are also generally used for trams and electric locomotive trains.
