Which geometric relation flag indicates that the sketch entities are coincident?

In SolidWorks, the geometric relation that indicates two sketch entities are coincident means that they occupy the same space at a single point. The coincident relationship allows for entities to be connected at specific points, ensuring that one entity is anchored at the endpoint of another, for example, allowing a point to be positioned exactly on a line or curve.

When the sketch entities are marked with a specific flag for a coincident relationship, it visually indicates their connection and reinforces the constraint that keeps the dimensions and positions of those entities linked. This is important in creating functional and parametric models where dimensions and configurations change while maintaining the integrity of the design.

Other relations like parallel, perpendicular, and collinear have distinct geometric meanings. Parallel indicates that two lines will never meet, remaining equidistant from each other. Perpendicular refers to lines that meet at a right angle, and collinear refers to points or lines that lie on the same straight line. Intersecting, on the other hand, deals specifically with two entities meeting at a point, which is closest to the concept of being coincident. Thus, identifying coincident sketch entities is essential for ensuring precise and expected behavior in modeling.
