What is the function of the Equal constraint in a sketch?

The function of the Equal constraint in a sketch is to ensure that line segments are equal in length. When this constraint is applied, any changes made to one line segment will automatically be reflected in the other line segments that share this constraint. This feature is particularly useful in designs where symmetry or uniformity is required, as it allows for quick adjustments while maintaining the relationship between those segments.

For example, if you have two lines in a sketch that you want to be the same length, applying the Equal constraint means that if you modify the length of one line, the other line will update to match that length. This promotes efficiency in design and helps maintain control over the geometry of your sketches.

The other options do not accurately describe the core function of the Equal constraint. Limiting angles pertains to the Angular constraint, placing objects at equal distances is related to an appropriate spacing method rather than Equal, and grouping similar shapes corresponds to a different approach in sketch management, possibly involving other constraints or design techniques.
