From FreeCAD Documentation
  1. Make Sketch001 visible, and hide Sketch and Mirrored001.
  2. Click Create sketch and create a new sketch attached to the YZ_Plane. The sketch will be named Sketch004.
  3. Click Create polyline and trace a polyline like that indicated by the points P1, P2, P3 and P4 in Fig: CH1.
  4. Remember to close the polyline by picking the first point. This will create the required Coincident constraint.
  5. Exit the tool.
  6. Check the applied constraints:
  7. Click External geometry
  8. Select the line defined by EGP1 and EGP2 in Sketch001, indicated by the purple color in Fig: CH2.
  9. Exit the tool.
  10. Apply a Point onto object constraint to P3 and the external geometry, and repeat this for P4. This will make the line defined by P3 and P4 coincident with the line defined by EGP1 and EGP2.
  11. Select the line P3 to P4, apply a Distance constraint, and assign Length = 17 mm
  12. Select the points EGP2 and P4, apply a Distance constraint, and assign Length = 7 mm.
  13. This will result in a fully constrained sketch like Fig: CH2.
  14. Click Close.
  15. Hide Sketch001.
