Which of the following line types is least likely to be used in an engineering drawing?

• A. Dimension Line
• B. Phantom Line
• C. Texture Line
• D. Center Line

Answer: (C)

In engineering drawings, each line type has specific uses that help convey information clearly and accurately. Texture lines, while they may indicate the surface finish or texture of a material, are not commonly utilized within standard engineering drawings. In contrast, dimension lines indicate measurements, center lines mark the axes of symmetry or features, and phantom lines are used to represent alternate positions or paths of motion. Since the primary goal of engineering drawings is to represent technical information such as dimensions, alignments, and features, texture lines do not play a fundamental role, making them the least likely line type to be used in such contexts.
