Do-it-yourself: make a success of your drawings

  • Draw an AB segment on the chosen support and locate its center O.
  • Set the compass spacing along the length of this segment.
  • Prick the compass in A and draw an arc of the circle above the center O.
  • Then prick the compass in B and draw another arc.
  • Then connect the center O and the intersection of the two arcs. This segment is perpendicular to the AB axis.
