Which projection method is used in the United States?

Which projection is used in the United States quizlet?
First-angle projection is the multiview projection convention used in the United States. Ordinarily, in selecting the front view, the object is placed to obtain the smallest number of hidden surfaces. In making an orthographic multiview drawing, one view should be completed before starting the others.
Which countries use 1st angle projection?
First angle projection is widely used in India and European countries. The object is placed between the observer and projection planes. The plane of projection is taken solid in 1st angle projection.
Which type of projection is most realistic?
perspective projection
Which pictorial sketch is the most realistic in appearance but the most complex to draw?

Is HB or 2B better for drawing?
2B pencil is darker in color and lower in hardness. It is suitable for drawing and painting all kinds of cards. But HB pencil is not. It has high hardness and is not easy to break.
Is 2B harder than HB?
Most pencil manufacturers outside of the U.S. use this scale, using the letter “H” to indicate a hard pencil. Today, however, most pencils using the HB system are designated by a number such as 2B, 4B or 2H to indicate the degree of hardness. For example, a 4B would be softer than a 2B and a 3H harder than an H.
Which is darker 2B or 4B?
2B is harder than 4B and 4B is harder than 6B. However, these are all on the soft side (B). The following is the standard scale.
Which is darker HB or 2H?
Grades of drawing pencils are organized in a scale based on softness or hardness. An “HB” pencil is found directly in the center of the scale. Therefore, a “4H” pencil will produce lighter marks than an “2H” pencil while a “4B” pencil will make darker marks than a “2B” pencil.
