Yes, when I started my drawing class, I didn't really like to draw by hand that much and on top of that, I spent my last two years of highschool in an architectural and engineering design course at a technical high school. My drawing professor had to beat all those perfectly straight lines out of me, but it was worth it and I passed. I started out with a self portrait that was horrible, but was able to finish the quarter being able to draw decent portraits.
A pantograph can be used to trace a drawing by placing a point on the existing drawing and using another point, side by side, on the other paper drawing out the particular drawing. A pantograph looks like a is two rulers in the shape of a "V" that are connected by 4 points. One "V" is inverted.
The two best ways to create depth in a drawing are perspective and shading. Perspective simply involves drawing an object as it would appear to you. For example, something further away would appear smaller than something right in front of you. Shading involves darkening the area in which shadow would normally fall. For a more realistic picture, focus on a light source so all areas exposed to the source would be lighter than those shadowed from it.
Artistic and technical drawing have different goals. Artistic drawing may replicate nature or convey an emotion, but it is meant to be looked at. Technical drawing replicates real things, and it is meant to communicate practical information about the subject.

There are two ways to construct a segment. One way is drawing the perpendicular bisector, the second is with a ruler.
Assuming a standard deck of 52 cards with aces counting as 1 and all face cards counting as 10, there are: 16 ways of drawing an ace and an 8, 16 ways of drawing a 2 and a 7 16 ways of drawing a 3 and a 6 16 ways of drawing a 4 and a 5, for a total of 64 ways to draw 2 cards whose sum is 9. There are 52!/(50!2!) = 1,326 ways to draw two cards, so the probability is 64/1326 = 0.048, or about 1 in 21.

One major reason is that the bonds are actually in three dimensional space, but most drawings utilize only two dimensions, and no two dimensional drawing can exactly and fully represent a three dimensional reality.
