  • Using the move tool brings both of their endpoints to the upper geometry
  • Using rotate command and taking the base point as the intersection point of 1st and second geometry join them.

• At first, take the X line command and draw a horizontal random line.
• create the offsets to the top for horizontal lines in the following distances :
  • 0.50
  • 2.50
  • 3.50
  • 5.50
• In the same way, create a vertical random line on it and take create offsets to the left side for that as follow:
  • 2.00
  • 4.50
  • 2.50

• And then trim the unwanted outer and inner lines as shown in the figure of the question.
• ESC.
