What happens if you hold down the Shift key while drawing a line?

• A. It will draw a curved line
• B. It will draw a line at a major angle (45 degrees, 90 degrees, 315 degrees, etc...)
• C. It will snap to grid points
• D. It will change color

Answer: (B)

Holding Shift when drawing a line constrains the direction to fixed angles. While you hold the key, the line snaps to common directions like horizontal, vertical, and diagonals, so you can quickly create a precise line at 45-degree or 90-degree increments (for example, 45°, 90°, or 315°). This makes alignment with other geometry easy and accurate without guessing. It’s not about curves, grid points, or color changes—the Shift constraint is all about locking the angle of the line.
