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.
Hi
One thing that can cause a technical drawing to be inadequate or misinterpreted is the unit of measure used for each area. Each area must follow a direct scale. This means that an area that is drawn to 1/4 scale will make the entire drawing follow 1/4 scale.

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.
