Final answer:
Grid, snap, and ortho are tools or features commonly used in Computer-Aided Design (CAD) software to create accurate and precise designs.
Step-by-step explanation:
Grid, snap, and ortho are examples of tools or features commonly used in Computer-Aided Design (CAD) software. These features help in creating accurate and precise designs.
Grid: It is a series of lines that form a network of horizontal and vertical reference lines. The grid helps in aligning and positioning objects or elements in a CAD drawing.
Snap: It is a feature that allows objects or elements to snap or align to specific reference points or grid intersections. This helps in ensuring precision and accuracy in CAD designs.
Ortho: It is a mode in CAD software that restricts the movement or drawing of lines or elements to the horizontal or vertical directions only. This feature simplifies the creation of straight lines in CAD drawings.
