When the hypothetical cutting plane cuts a part of the plan vertically and the cutting is done from the lowest floor i.e. underground to the highest floor, this state is called cross-section or building cut.

In a plan, choosing the location of the section is extremely important. This importance is such that the cutting and crossing place of this hypothetical plane should be from the part that provides the designer with the most data from inside the building.

It is possible to cut doors, windows, walls, patios and stairs in the path of the cutting board, and the designer can show how to cut them with the cutting board by drawing section maps.

One of the most important construction and construction plans that are needed by executives and engineers are sections. The relationship between the building and the ground, the number of floors and internal walls is determined by drawing sections.

In most cases, the number of sections required for building plans is determined by the size of the building and the complexity of its internal parts.

Signs used in the section

Cutting line in the plan

The cutting line is usually used to show the location of the vertical cut on the plan. This line is drawn with a thick non-continuous type and at both ends, the direction of vision is determined by arrows.

Hashore in the cut

In order to show the type of materials used in the cut parts of the structure, special hatches are often used, each of which defines a type of material.

In most cases, the angle of drawing the hatch is 45 degrees, and a thin continuous line is used to indicate it. Usually, the 45-degree lines of the hatches are drawn with a 45-degree ruler.

Scale in slices

In most cases, sections are drawn and designed with the scale of architectural plans, i.e. 1/50, 1/100, and 1/200.

But if needed, partial cuts may be drawn whose scale is one twentieth to one tenth and they are called details.

Cut measurement

The measurements taken in the cuts are done vertically. In the vertical measurement, it is usually done as shown in the figure below, drawing the height of the door, the height of the window and its bumpy wall, the height of the parapet wall, etc.

Cut coding

Coding in cuts is usually done for each of the floors.

Axing cutting

Axing can also be applied to cutting. As a result, the location of the columns can be shown by means of the axes that are seen when drawing the section.

After we accurately draw the axes, we can also measure the distance between them. Axes arrangement and the size between them should be in accordance with the axes inside the plan.
