Scale ratio

 What is Scale ratio?

The scale ratio of a model represents the proportional ratio of a linear dimension of the model to the same feature of the original.

Why are scale drawings or models important?

Scale drawings and models are fundamental to creating products that are both useful and pleasing to the eye. See also Computer-Aided Design, Mount Rushmore, Measurement of Photocopier, Ratio, Rate and Proportion Transformations.

How are they useful in real world scenarios?

A scale drawing of a building (or bridge) has the same shape as the real building (or bridge) that it represents but a different size. Builders use scaled drawings to make buildings and bridges. A ratio is used in scale drawings of maps and buildings.

List four fields in which scale drawings or models are used:

.Architects & Engineers

. Designer

. Construction

. Cartographer

.Architects & Engineers- Having the correct scale will directly determine how walls become rooms and dirt becomes roads. The space outlined on a scale drawing is also reduced by the same ratio as the objects included in the plan. If a drawing isn't to scale, there's no guarantee that each object on the plan will fit into the real space.

. Designer- Scale, and proportion both are integral to establishing what interior designers call the golden ratio. This ratio, 1:618 is a nearly foolproof method for determining which colors, shapes, sizes, and positioning to implement within an interior space. Contrast is important in creating a unique and inspiring space.

. Construction- Drawing accurately to scale, and being able to shift between scales, is a fundamental skill of architectural drawing and spatial design. Scale drawings are used to illustrate items that it is not useful or convenient to draw at their actual size.

. Cartographer- Scale is probably one of the most important elements of cartography and map analysis. It creates some amount of objectivity in the map and provides a reliable means of assessing the size or relative distances of features pictured on a map.
