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.
What is the angle used in isometric projection?
always 30 degrees
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 countries use 1st or 3rd Angle Projections?
First Angle Projection is primarily used in countries such as India, Australia, and most of Europe, while Third Angle Projection is favored in the United States, Canada, and some parts of Asia. The choice between these two methods often reflects regional standards in engineering and technical drawings. Each projection method differs in how objects are represented on a two-dimensional plane, influencing how designs are interpreted and communicated.
What is the definition of the first angle angle projection?
In first-angle projection, the projectors originate as if radiated from a viewer's eyeballs and shoot through the 3D object to project a 2D image onto the plane behind it. The 3D object is projected into 2D "paper" space as if you were looking at a radiograph of the object: the top view is under the front view, the right view is at the left of the front view. First-angle projection is the ISO standard and is primarily used in Europe.
Why second and third angle projections not used in orthographic projections?
because 2nd and 4th angle projection overlap each other

Why can not we use second angle projection method in Engineering drawing?
In 1st angle projection the front view will be in the top of the xy plane and the top view will be in the bottom of the xy plane .In 3rd angle projection the top view will be in the top of the xy plane and front view will be in bottom of the xy plane. dis will give a clear view.i hope u know dis... but in 2 angle projection both the views(front and top) will be in the top of the xy plane and in 4th angle projection both the views (front and top) will be in the bottom of the xy plane... since both the views will be in one side of the xy plane, its not possible to draw... both views will merge... to get more clear view, refer any basic engineering drawing book.......

Why we use sine angle in cross product while cos angle in dot product?
Because in dot product we take projection fashion and that is why we used cos and similar in cross product we used sin
What is the lateral ankle projection?
The lateral ankle projection is an X-ray view that shows the side of the ankle joint. It is used to assess for fractures, dislocations, and arthritis in the ankle joint. The patient may need to position their foot at a 90-degree angle to their leg for this projection.
Which projection is used by nearly all seagoing navigators?
the Mercator projection
The projection note for any map sheet identifies the projection system used on the map sheet?
True. The projection note for any map sheet identifies the projection system used on the map sheet.
Map projection is used for sea travel?
A map projection that is used for sea travel includes the gnomonic projection. This was most often used to find the shortest routes between points on a sphere.
Is a isometric projection used for developing a multiview drawing?
No, a multiview projection is used for developing a multiview drawing. Multiview projections are orthographic projection where the object is behind the plane of projection, and is oriented such that only two of its dimensions are shown.
What strategies can be used to estimate an angle?
Look at whether it is acute, obtuse or reflex. Then, look at the acute component of the angle and try to estimate whether it is half a right angle (45 deg), a third (30 deg) or two third (60 deg). If you are good, then you could try estimating "between a third and a half = 35-40 degrees".
