These kinds of puzzles that challenge you to trace the figure without crossing a line and going over each line only once is called a Euler Path. Points where lines meet are given a numerical score based on how many lines meet there. The top and bottom of the circle have a score of three, the rhombus in the middle is crossed by the diameter and both intersections have a score of four.
If an Euler Path has at most two points with an odd number value, then it is solvable. Three or more odd numbered intersections means it cannot be solved.
This puzzle is solvable.
