To sketch a line, you must...

To sketch a line effectively in Solid Edge, the process involves selecting a start point and then defining an endpoint. By clicking once at the desired start point, the software registers this as the beginning of your line. Then, a second click at the endpoint establishes the line's termination and finalizes its length and orientation.

This direct method of defining a line is intuitive and aligns with standard practices in many CAD programs, where precision is essential. The clarity of specifying distinct points enhances control over the line's attributes, providing a straightforward approach to drafting and modeling in the software environment.

Each of the other methods does not conform to how Solid Edge expects line sketches to be created. Holding down to draw or clicking and dragging can lead to more fluid shapes, which may not yield the precise straight lines intended. Using the dimensioning tool is also unrelated to the initial act of sketching the line; it comes into play later for accurately modifying dimensions of the sketch once it's already established. Thus, the correct method is clearly defined by the process of selecting two specific points on the canvas.
