A diagraph
A protractor
A Combined Services Drawing, or CSD, is used in construction. It is an illustration that provides a visual way to look at proposed development plans.
An eidograph is a mechanical device used to reduce or enlarge the scale of a drawing or make a copy of a drawing at the same scale. It is similar in use to a pantograph, but was generally considered to be more accurate. It was invented by an Englishman in the 1820's and was used into the early 1900's.
A drawing that is a smaller representation of a real object is called a scale drawing. Scale drawings maintain the proportions of the original object while reducing its size, allowing for easier visualization and planning. They are commonly used in architecture, engineering, and design to convey dimensions and layouts accurately.
Hi
A protractor
to measure angles.
A protractor.
A protractor is the common tool used in mathematics for measuring and drawing angles.
A protractor is commonly used for drawing and measuring angles. It is a tool with a semicircular shape that is marked with degree measurements. By aligning the center of the protractor with the vertex of the angle, you can accurately measure and draw angles.

An instrument used for drawing and measuring angles
Degrees are a measure of angular separation, not distances. You cannot, therefore, use the protractor for determining distances.
Not all drawings are done to scale, sketches of buildings and people for instance. However if it is a technical drawing the draughtsman/woman will state on the drawing the scale used.

A1 drawing boards are mostley used for builders when designing houses or small scale shops they are not used for huge scale developments.
