  1. Double click Sketch002 to enter edit mode.
  2. Rotate the view so you can clearly see the points as shown in Fig: CC2. This will ease subsequent steps. Note that the rectangle's initial position may be different in your sketch.
  3. Click External geometry.
  4. While the tool is active the cursor has this appearance:
  5. Select point P1 in Fig: CC2. The selected point is added to the sketch as external geometry. In the Elements section of the task panel it will appear with a purple X icon or, introduced in version 0.21, a purple dot icon.
  6. With the tool still active select point P2 in Fig: CC2. This external geometry should also appear in the Elements section.
  7. Exit the tool.
  8. Select point P1 and point P3 and apply a Vertical constraint. The rectangle will be aligned with the X position of P1.
  9. Select point P2 and point P3 and apply a Horizontal constraint. The rectangle will be aligned with the Y position of P2.
  10. You should have a fully constrained sketch similar to Fig: CC3.
