[0002] Ruler and compass drawing is usually carried out with a ruler and a compass. The specific method depends on the figure to be drawn and the given conditions. Ruler and compass drawing is a method of drawing geometric figures using a ruler and a compass. It has a wide range of applications in mathematics, geometry and engineering. Ruler and compass drawing involves basic concepts, tools, principles, steps, and common drawing methods. It also involves precision control and error analysis, shares practical application cases, and provides tips for skill improvement and practice. Ruler and compass drawing requires the draftsman to accurately draw various geometric figures using these two basic tools through limited steps. Ruler and compass drawing not only tests the draftsman's geometric intuition, but also exercises his ability to control precision. It is not only an important part of mathematics learning, but also an indispensable skill for engineers, architects and other professionals in the design and drawing process. The existing ruler and compass drawing quality process is completely based on the draftsman's drafting experience. It cannot accurately identify the size and shape errors of the drawing lines in the ruler and compass drawing process, nor can it realize intelligent correction of the draftsman's drawing line errors, which reduces the applicability and quality of ruler and compass drawing.

[0003] The Chinese invention patent with announcement number CN117934976B discloses an AI-based automatic correction system and method for ruler and compass drawing operations.
