A scale of 1 cm to 3 meters means that for every 1 centimeter measured on the drawing, it represents an actual distance of 3 meters in the real world. This type of scale is commonly used in architectural drawings to provide a more manageable size for representing large structures.
To understand how the scale drawing relates to the building:
-
Proportional Representation: The drawing is a proportionate representation of the actual building. If a feature of the building is 9 meters in real life, it would be represented as 3 centimeters on the drawing because 9 meters divided by 3 meters/cm equals 3 cm.
-
Measurement Reference: The scale allows anyone examining the drawing to interpret the dimensions and layout of the building accurately. By measuring distances on the drawing, one can calculate the corresponding real-world dimensions.
-
Visualization: The scaled drawing helps architects, builders, and clients visualize the building's size and layout without needing to refer to full-scale blueprints or visit the actual site.
-
Planning and Design: It aids in planning and design discussions since the drawing can be used to assess the building's design, functionality, and aesthetics in a more manageable size than the actual building.
Overall, the scale provides a convenient way to communicate important information about a building's dimensions and layout in a format that is easier to work with.
