An architectural drawing, also known as a building plan, is a type of technical drawing that shows the design of a building. It is used to communicate the architect’s ideas to builders and other professionals involved in the construction process.
There are many different types of architectural drawings, each with its own specific purpose. Some of the most common types include:
- Floor plans show the layout of a building from above.
- Elevations show the exterior of a building from different sides.
- Sections show the interior of a building, cutting through it vertically or horizontally.
- Details show specific parts of a building, such as windows, doors, or moldings.
Architectural drawings are an essential part of the construction process. They help to ensure that the building is built according to the architect’s design and that it meets all safety and building codes.
1. Establish a horizon line. The horizon line is the imaginary line that divides the earth from the sky. It is important to establish the horizon line before you start drawing the arch, as it will help you to determine the perspective of the arch.
Establishing a horizon line is an important first step in drawing a 1PP arch because it helps to create the illusion of depth. The horizon line divides the drawing into two halves: the upper half, which represents the sky, and the lower half, which represents the ground. The arch is then drawn on the horizon line, creating the illusion that it is receding into the distance.
Without a horizon line, the arch would appear to be floating in space. The horizon line provides a reference point for the viewer, helping them to understand the perspective of the drawing. It also helps to create a sense of scale, making the arch appear larger or smaller depending on its position relative to the horizon line.
Here is an example of how establishing a horizon line can help to create the illusion of depth in a drawing of a 1PP arch:

As you can see, the horizon line helps to create the illusion that the arch is receding into the distance. The arch appears to be larger at the bottom than at the top, which is a natural effect of perspective. This effect would not be possible without a horizon line.
Establishing a horizon line is an essential step in drawing a 1PP arch. It helps to create the illusion of depth, scale, and perspective. By following these simple steps, you can create a realistic and convincing arch that will add depth and dimension to your drawings.
2. Draw a vertical line. The vertical line will be the center of the arch. It should be perpendicular to the horizon line.
Drawing a vertical line is a crucial step in drawing a 1PP arch because it establishes the center of the arch and ensures that the arch is symmetrical. The vertical line also helps to create the illusion of depth by dividing the drawing into two halves: the upper half, which represents the sky, and the lower half, which represents the ground. The arch is then drawn on the vertical line, creating the illusion that it is receding into the distance.
-
Establishing the Center of the Arch
The vertical line establishes the center of the arch, which is important for creating a symmetrical arch. A symmetrical arch is more pleasing to the eye and appears more balanced and stable. Without a vertical line, it would be difficult to ensure that the arch is symmetrical, and the arch may appear or off-center.
-
Creating the Illusion of Depth
The vertical line also helps to create the illusion of depth in the drawing. By dividing the drawing into two halves, the vertical line creates a sense of space and distance. The arch is then drawn on the vertical line, creating the illusion that it is receding into the distance. This effect would not be possible without a vertical line.
-
Guiding the Placement of Other Elements
The vertical line also serves as a guide for placing other elements of the drawing, such as windows, doors, and moldings. By aligning these elements with the vertical line, you can create a more cohesive and balanced composition. Without a vertical line, it would be more difficult to ensure that these elements are placed correctly, and the drawing may appear cluttered or disorganized.
Overall, drawing a vertical line is a critical step in drawing a 1PP arch. It establishes the center of the arch, creates the illusion of depth, and guides the placement of other elements in the drawing. By following this step, you can create a more realistic and convincing arch that will add depth and dimension to your drawings.
3. Draw two points on the horizon line. These points will be the endpoints of the arch. The distance between the two points will determine the width of the arch.
Drawing two points on the horizon line is a crucial step in drawing a 1PP arch because it determines the width of the arch. The distance between the two points establishes the span of the arch, which is the horizontal measurement of the arch’s opening. The width of the arch affects the overall proportions and appearance of the drawing, and it also influences the placement of other elements, such as windows and doors.
Here are some key points to consider when drawing two points on the horizon line for a 1PP arch:
- The distance between the two points should be proportional to the overall size of the arch. A wider arch will require a greater distance between the two points, while a narrower arch will require a smaller distance. The proportions of the arch should be carefully considered to create a visually balanced and aesthetically pleasing drawing.
- The placement of the two points on the horizon line should be carefully considered. The position of the arch within the drawing will be determined by the placement of the two points. The arch can be positioned in the center of the drawing, or it can be offset to one side. The placement of the arch will affect the overall composition of the drawing.
- The two points should be level with each other. This will ensure that the arch is symmetrical and balanced. If the two points are not level, the arch will appear lopsided and distorted.
Drawing two points on the horizon line is a fundamental step in drawing a 1PP arch. By following these guidelines, you can create a realistic and convincing arch that will add depth and dimension to your drawings.
Example:In the following example, the two points on the horizon line are placed relatively close together, creating a narrow arch. The arch is positioned in the center of the drawing, creating a balanced and symmetrical composition.

These examples illustrate how the distance between the two points on the horizon line can affect the width and placement of the arch, and how these factors can be used to create different visual effects in a drawing.
4. Connect the points with curved lines. The curved lines will form the sides of the arch. The curvature of the lines will determine the height of the arch.
This step is crucial in the process of drawing a 1PP arch as it defines the shape and height of the arch. The curvature of the lines determines how high the arch will be and how wide it will appear. By carefully controlling the curvature of the lines, you can create a variety of different arch shapes, from a gentle curve to a more pronounced pointed arch.
-
Creating the Shape of the Arch
The curvature of the lines you draw will determine the shape of the arch. A gentle curve will create a more subtle arch, while a more pronounced curve will create a more pointed arch. The shape of the arch should be carefully considered to match the overall style and tone of the drawing.
-
Determining the Height of the Arch
The curvature of the lines will also determine the height of the arch. A greater curvature will create a taller arch, while a lesser curvature will create a shorter arch. The height of the arch should be proportional to the overall size of the drawing and the other elements within it.
-
Creating a Balanced Composition
When drawing the curved lines of the arch, it is important to consider the overall balance of the composition. The arch should be visually balanced with the other elements in the drawing, such as the horizon line and any other objects or figures. A well-balanced composition will create a more pleasing and harmonious drawing.
By carefully following these steps and considering the factors discussed above, you can create a realistic and convincing 1PP arch that will add depth and dimension to your drawings.
