What is the difference between first and third angle drawings?
It is just where the elevation is positioned, first angle, the drawings is positioned to the right of the section and third, the elevation is positioned to the left of the section, obviously rotated the correct way too.
How do you interpret first and third angle projection?
The front elevation is in the centre in both projections. In 1st angle projection the end elevation is on the opposite side of the front elevation and the plan view is below the front elevation. In 3rd angle projection the plan view is above the front elevation and the end elevations are on the same side as viewed
Why you not using 2nd and 4th angle projection?
Second and fourth angle projections are rarely used in technical drawing because they can lead to confusion and misinterpretation. These methods do not align with standard practices, which favor first and third angle projections for clarity and consistency across industries. By adhering to the more commonly accepted projections, engineers and designers ensure that their drawings are easily understood by others. Thus, using first and third angle projection simplifies communication and reduces the risk of errors in manufacturing or assembly.
What angle is corresponding angle to another angle?
A second angle measuring 90 degrees minus the first angle.
What is the difference between first and third angle drawings and imperial and metric systems of measurements?
In first angle drawings, the front view is on the lower left, with the side view to its right and plan view above it. On a third angle drawing, the front view is to the lower right, with the side view to the left and plan view above it. The metric system of measurement is based on a base 10 plan, with each unit having specific multiples that are powers of ten, e.g., kilo, meaning 10^3 units or milli- meaning 10^-3 units. In contrast, the imperial system uses varying lengths, such as 16 ounces in a pound or 12 inches in a foot.
How do you interpret first and third angle drawings?
First angle is interpretted by the drawing being positioned to the right of the section and third angle is interpretted by the elevation being positioned to the left of the section.
What is the difference between first and third angle drawings?
It is just where the elevation is positioned, first angle, the drawings is positioned to the right of the section and third, the elevation is positioned to the left of the section, obviously rotated the correct way too.
How long people have been drawing?
Early man would draw on cave walls using charcoal (burnt sticks) and other materials. These drawings would record and explain events like a hunt or a battle. These are the first known drawings.
Where were the first drawings found?
It depends... the first drawings were said to be found in the caves of the Aboriginal tribes in Australia, but there are also early drawings in Egypt that were called heiroglyphics. Thankyou!
What was the first drawing?
Cave drawings.
To trisect a right angle you first construct an triangle?
equilateral * * * * * * * No its right. Apex is stupid in ways no one can explain so yeah...
Why did drawing start?

What is the disadvantage of using isometric drawings?
One disadvantage of using isometric drawings is that they can sometimes distort the true dimensions of an object, making it challenging to accurately represent the size and proportions of the object. Additionally, isometric drawings can be more complex to create compared to other types of technical drawings, such as orthographic projections. Lastly, isometric drawings may not always provide all the necessary information needed for precise engineering or design purposes, as they do not show all sides and angles of an object simultaneously.
Is there a picture of the first car ever made?
there are drawings
How do you interpret first and third angle projection?
The front elevation is in the centre in both projections. In 1st angle projection the end elevation is on the opposite side of the front elevation and the plan view is below the front elevation. In 3rd angle projection the plan view is above the front elevation and the end elevations are on the same side as viewed
How did drawings began?
For one thing, drawing began way long time ago. The caveman was the first historic human drawings
What kind of hominid was the first to produce cave drawings?
a caveman?
