The cross section of the quick question is the main content that people can see in the state of expressing the cross section, and the bottom line of the beam can definitely be seen, so drawing it is very simple. As for how to draw it, the beam of 400mm is generally drawn in proportion in the room (if the height is 2mm according to 1: 200). The corresponding increase of large span will make a difference.

There is no logical connection between lightness and site form, and lightness can be divided into three ways: 1 is a simple combination of shapes (there are no more than three main geometric shapes of the combination), and it is square or spherical, conical or hemispherical according to the situation, that is, it has a sense of volume, clear combination logic and clear priorities; Second, through the "surface", that is, the smooth surface, it is suddenly lit up, such as the curved walls of libraries and museums in Gehry; The third is the structure inside the plane, for example, the overhead on the ground floor is light, the building with corridor is light, and the building with large area of transparent glass is light, which increases the proportion of imaginary part in the actual situation of the building.

There are no strict definitions of monomers and groups. You can connect each unit with a corridor. This is not absolutely impossible, but another meaning of monomer is that it can be used and managed independently. So if the corridor is closed, many buildings of Unicom can also be regarded as one building. The understanding of the monomer should be to see whether the functions can be combined into one (for example, the office and exhibition of a museum constitute a museum) rather than to see the division (dispersion) on the plane. It is certainly a good thing to disperse the layout when the land is not tight, but at the same time, the weakening of the connection between various parts is also a disadvantage, which should be weighed according to the specific situation.

The basement involves waterproof, moistureproof and civil air defense. These are beyond the depth of undergraduate study, so generally do not take the exam, quick exam is the basic skill. Wuhe recruits people through a small house of 600 square meters, and it is a basic skill (even the size of the steps can see the basic skills).

You need to find someone to correct your quick questions, which will improve quickly.

Supplement: There is something wrong with your picture. You seem to have drawn a pilaster? If the wall is cut, it should be filled. You didn't draw it. And the expression of the outdoor steps on the right is not clear (it looks like aproll, and the steps should be at least three steps, so you drew a hurdle).
