It depends on the purpose and type of the drawing.
If the scale would be necessary for proper interpretation of the drawing (e.g. mechanical drawing, plans for a building) then yes.
If the scale would not help in interpreting the drawing (e.g. electronics schematic, software data flow diagram) then no.
A non projective engineer's drawing is done without using any instruments like triangle and scale. Such a drawing is also called a sketch or free hand drawing.
A technical drawing is drawn precisely to a scale. Measurements taken from the drawing can be scaled up to produce or build a full size structure or machine, etc. A freehand drawing could be a simple sketch, detailed drawing, rough doodle, of a subject and is classed as a picture.
A perspective drawing represents an object in a way that mimics human eye perception, showing depth and distance by converging parallel lines towards a vanishing point. This creates a more realistic view, where objects appear smaller as they recede into the background. In contrast, an isometric drawing uses parallel lines to represent the object's dimensions without any perspective distortion, maintaining equal scale regardless of depth, resulting in a more technical and schematic appearance. Consequently, perspective drawings tend to be more visually engaging, while isometric drawings offer clarity in measurements and proportions.
An isometric drawing is a schematic detailing a three-dimensional object in an abstract space that has no vanishing point. So, you can see the thickness of the object, but all sides remain parallel, unlike how objects appear in real life. In real life, the sides of an object converge as they get farther and farther from the eye. Think of a building whose sides slope into a point off in the distant horizon. These drawings are helpful in giving precise measurements, scale, placement and proportions. A good example of an isometric drawing would be the assembly instructions that come with a piece of household furniture.
The mini-drafter is a versatile tool and can be used for almost everything. It can be used to draw parallel lines, perpendiculars, inclined lines of any degree with unmatched speed. it consists of one long scale and one small scale and the scales are shaped in 'L' shaped and by a mini drafter we can do 3 kinds of works : 1) drawing of lines 2)drawing perpendiculars for the lines 3)we can use that as a protracter simultanously
The answer depends on what aspect of the scale drawing you wish to calculate.
It shows the constant of proportionality between the scale drawing and the real-life object.
it depends of the scale of the drawing
# is the ratio of the demensions in the drawing to the corresponding actual dimensions. The scale factor for a scale drawing is the ratio of the dimensions in the drawing to the corresponding acual bimensions.
scale questions
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.
a scale drawing.
A drawing of the object in scale.
The scale factor of a scale drawing is the ratio of any length in the drawing to the true corresponding length in the "real" object.
With an accurate complete scale drawing and the scale provided, you can determine the actual dimensions of the object represented in the drawing. By measuring the length of a feature in the drawing and applying the scale factor, you can convert that measurement to the real-world size. This method allows you to find various measurements, such as height, width, and depth, depending on what is represented in the drawing.
The scale drawing in math is fun. You have to know the challenge level of the basic Mathematics.
