What is the use of a French curve in surveying?

Setting straight lines in the field
Drawing smooth curves with varying radii
Measuring angles precisely
Determining distances between points

The correct answer is: Drawing smooth curves with varying radii

A French curve is primarily designed to aid in drawing smooth curves with varying radii, making it an essential tool in drafting and design work, including surveying. When working on maps, plans, or profiles, surveyors may need to represent smooth transitions and curves accurately rather than just straight lines or angular changes. The unique shape of a French curve allows the user to create various curve shapes that can adjust seamlessly, which is crucial for representing features like roads, property boundaries, or natural terrain in a refined manner. By utilizing a French curve, a surveyor can ensure that the curves maintain a consistent radius and flow, contributing to quality technical drawings and accurate representations of land features. This tool is particularly useful in the final stages of drafting when laying out complex curves that require visual appeal and technical accuracy, essential for effective communication and understanding of survey data.
