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
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.
What angle is corresponding angle to another angle?
A second angle measuring 90 degrees minus the first angle.
Advantages of a third angle drawing?
Third angle projection is in common use in the USA, Canada, and the UK. The rest of the world more commonly uses first angle. There is no inherent superiority of one projection over the other. When you are making drawings that may be used internationally, it's a very good idea to indicate by a small symbolic diagram which projection is in use. This diagram is usually a side and end view of a truncated cone.
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.

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.
What is the disadvantage of using isometric drawings?
v Orthographic drawingØOrthographic drawings are orthographic projection drawings. These can be drawn at first angle projection and third angle projections.ØI am going to explain orthographic third angle projection drawing because I use them.ØIf I want to draw orthographic third angles projection drawing I have to follow some rules.ØThese rules are:ØThe view from the front is in the middle.ØThe view from the left is on the left.ØThe view from the right is on the right.ØThe view from the top is on the top.ØThe view from the bottom is on the bottom.ØThe view from the rear/back is on the far right.Example of orthographic third angle projection.Orthographic drawing advantageOrthographic drawing disadvantageEasy to recognized /read and understand by engineers.Hard to recognized by other people then engineers.Doesn't looks like at all to real design/picture.
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...
