What command is utilized to set lines or edges at a 90-degree angle to each other?

The Perpendicular command is specifically designed for the purpose of aligning lines or edges at exactly a 90-degree angle to each other. When using this command, users can easily ensure that one line is positioned in a way that it meets another line at a right angle, which is essential for creating accurate geometric constraints in sketches or models. This is particularly useful in engineering and design applications, where precise angles are crucial for functionality and aesthetics.

The other choices do not serve the same purpose. For instance, the Right Angle command isn't a standard term in Solid Edge for achieving this alignment, and while Angle Snap relates to adjusting angles when drawing, it doesn't specifically ensure that two lines will be at a right angle. The Align command typically assists with the general alignment of objects but does not enforce a 90-degree relationship specifically. Thus, the Perpendicular command is the appropriate tool for achieving the intended result of creating right angles between lines or edges.
