The Rainbow Tool Attachment

Description

Create multiple perfectly aligned curves in a single movement.

The Rainbow Tool Attachment is designed for the Arc Precision System, allowing you to use multiple markers simultaneously to create perfectly spaced, parallel arcs and curved designs.

Despite its name, it’s not just for rainbows. Use different colours, repeat the same colour, create decorative bands, or position markers to draw the inner and outer edges of a curved shape at the same time.

Multi-Colour Rainbow Effects

Load several markers at once and create multiple curved lines in a single smooth movement.

• Use multiple colours simultaneously
• Create clean, evenly spaced rainbow arcs
• Keep every colour perfectly aligned
• Build larger designs with consistent geometry

✏️

Multiple Markers – One Movement

Instead of drawing each curved line separately, the attachment allows several markers to follow exactly the same arc at the same time.

• Faster than drawing individual lines
• Maintains consistent spacing
• Reduces alignment errors
• Ideal for repeated parallel curves

---

🎯

Inner & Outer Outline Mode

The marker positions are spaced only a few millimetres apart, giving you another useful way to work.

Position markers to create the inner and outer outline of a curved band simultaneously.

Once both edges are drawn, simply fill the space between them.

• Draw two perfectly matched edges at once
• Create consistent-width curved bands
• Perfect for bold arcs and graphic designs
• Fill the centre afterwards for a clean, professional result

More Than Just Rainbows

The Rainbow Tool Attachment can be used for much more than traditional rainbow designs.

Create:

• Multi-colour arcs
• Parallel curved lines
• Decorative bands
• Inner and outer outlines
• Layered circular effects
• Repeating curved patterns
• Graphic mural elements

Experiment with marker position, spacing, and colour combinations to create completely different effects from the same attachment.

Designed for the Arc Precision System

The attachment integrates with the Arc Precision System, transforming the compass into a multi-marker curved-line tool.

Combine it with different system lengths to create anything from smaller curved details to large-scale mural arcs and circular designs.
