By stating the general surface finish in a general note (often pre-printed in the format). Any different finishes in the body of the drawing are indicated by a 'tick' symbol with the relevant surface finish value in Micometres or Microinches above the horizontal line of the tick.
answer:-to draw vetical and inclined lines
It is a blue print or a copy on paper for the specifications of an item to be produced or manufactured
A set square is a tool for marking angles in engineering and technical drawing, etc. They come in different angles and may be adjustable.
Scale drawing in math refers to a representation of an object that maintains proportional dimensions to the actual object but is either enlarged or reduced. It uses a specific ratio, called the scale factor, to determine the relationship between the dimensions of the drawing and the real-world dimensions. For example, a scale drawing might depict a building at 1:100, meaning 1 unit on the drawing equals 100 units in reality. This technique is commonly used in architecture, engineering, and design to create accurate representations of objects.
A drawing that shows a corner view of a three-dimensional figure is called an isometric drawing. This type of drawing represents three dimensions on a two-dimensional surface by using a specific angle, typically 30 degrees from the horizontal, allowing the viewer to see three sides of the object simultaneously. Isometric drawings maintain scale and proportions, making them useful for technical and engineering illustrations.
it is worthless in engineering drawing.
Any engineering object/task/product can be best demonstrated by drawing. Being general, not only engineering products, drawing helps understanding everything in science. However, drawing is used a lot in engineering specially, mechanical, cibvil, manufacturing, design etc branches. An engineer must be smart in drawing (understanding drawing & prepare drawing) to have sound reach in the material. Drawing is one of the languages of engineering. The other is mathematics.
A drawing of the object in scale.

Drafting means actually drawing the drawing.
Electronics engineering mainly deals with things like power,machines etc. And role of engineering drawing in electronics engineering can be defined as for making blue prints of the model.
what is instrumental figures in drawing
Engineering drawing shows the proper map of building which helps in deriving the estimation cost of building and also help in planning of construction.
Drawing is the language of Engineers. Any thing related engineering and technology are documented mainly through drawing only. The study about engineering drawings, its application and method of documentation is known as engineering graphics.
