Multi-function Drawing Ruler with 360° Magnetic Compass for Paper-Safe Circular Measurements

This 17cm metal drawing ruler revolutionises technical drawing by combining multiple functions in one compact tool. The magnetic compass base allows 360° rotation around the ruler unit, enabling perfect circle creation without piercing your paper. With a 234mm measuring range and machined stainless steel construction, this tool provides precise linear and circular measurements while incorporating French curve and proportional rule functions. The integrated design eliminates the need for separate compasses and rulers, streamlining your creative workflow.

Technical Features and Construction Quality

This multi-function drawing tool incorporates several technical innovations that enhance measurement accuracy and user convenience. The magnetic connection system between the ruler and compass base maintains perfect alignment while allowing full rotational movement. The stainless steel construction ensures dimensional stability and corrosion resistance, while the integrated modules provide multiple drawing functions in a single compact unit.

Magnetic Compass Design

The compass unit features machined stainless steel construction with a bottom positioning hole for secure placement. The magnetic connection to the 17cm ruler allows 360° rotation without losing alignment, enabling circular measurements up to the full compass range. This design eliminates the traditional compass needle that pierces paper, protecting your drawing surfaces while maintaining measurement precision. The compass also functions as a pen holder when not actively used for circular drawing operations.

Ruler Technical Specifications

The 17cm metal ruler provides a 234mm measuring range with linearly perforated markings for accurate measurements. The abstract rule component includes curved contours that serve as French curve guides for organic shapes and proportional measurements. The ruler's construction from solid stainless steel ensures it maintains straightness and measurement accuracy over extended use. The integrated bottle opener and key functions add practical utility beyond drawing applications.

Durability and Construction

Manufactured from machined stainless steel, this drawing tool resists bending and deformation under normal use conditions. The magnetic connection system maintains its holding power through repeated use cycles, while the ruler markings remain legible due to the perforated design. The solid construction ensures the tool maintains dimensional accuracy for precise technical drawing, architectural drafting, and artistic applications requiring reliable measurement instruments.

Professional and Creative Applications

This multi-function drawing tool serves various professional and creative applications where precise measurements and circular drawing capabilities are required. The combination of ruler functions with compass capabilities makes it suitable for technical drawing, artistic creation, and design work across multiple disciplines. The paper-safe circular drawing feature particularly benefits applications where surface preservation is important.

Technical Drawing Applications

Architects and engineers can use this tool for technical drawings requiring both linear measurements and circular elements. The 234mm measuring range covers common architectural details, while the compass function creates perfect circles for mechanical components and structural elements. The French curve capabilities assist in drawing organic shapes and complex curves often required in technical illustrations and engineering diagrams. The magnetic compass eliminates compass hole damage on valuable drawings.

Artistic and Design Uses

Artists and illustrators benefit from the combination of measurement precision and creative flexibility. The abstract rule with curved contours helps create organic shapes and flowing lines in illustrations and tattoo designs. Mandala artists can use the 360° compass rotation to create symmetrical patterns and circular designs without damaging their paper. The tool's compact size makes it suitable for field sketching and journaling where carrying multiple instruments is impractical.

Educational and Professional Versatility

Practical Benefits and Value This drawing tool provides several practical benefits that enhance workflow efficiency and measurement accuracy. The combination of multiple functions in one tool reduces equipment requirements and simplifies creative processes. The durable construction and precise manufacturing ensure long-term reliability and consistent performance across various applications and usage scenarios.
