The Draft Snap Ortho option snaps to imaginary lines that cross the previous point at multiples of 45°. The lines and angles are relative to the XY plane of the working plane coordinate system.

Snapping the second point of a line to an imaginary line that has an angle of 45° with the X axis. The small magenta circles indicate all possible directions.


For general information about snapping see Draft Snap.

  1. Make sure snapping is enabled. See Draft Snap Lock.
  2. If Draft Snap Ortho is not active do one of the following:
    • Press the button in the Draft snap toolbar.
    • Press the button in the Draft snap widget.
  3. Choose a Draft or BIM command to create your geometry.
  4. Note that you can also change snap options while a command is active.
  5. Pick a first point. This snap option requires a previous point.
  6. If you move the cursor around the previous point you will notice a "magnetic" effect when the cursor is on an imaginary infinite line crossing that point at an angle of 0°, 45°, 90° or 135°.
  7. The point is marked and the icon is displayed near the cursor.
  8. Click to confirm the point.
