Understanding Formulas in SeamScape

Formulas in SeamScape bring a dynamic and powerful element to pattern creation. They allow you to define relationships and calculations between different entities in your design. Here’s how formulas work:

Basics of Formulas

• Structure: Formulas in SeamScape resemble Excel formulas but do not require an equal sign (=) at the start.
• Dynamic Updates: When referenced values change, formulas automatically recalculate to keep your patterns updated.

Common Formula References

You can use formulas to reference various properties of paths, points, and custom variables. Here are some key references:

• PATH_NAME.length: Gets the length of the path named PATH_NAME.
• PATH_NAME.angle: Retrieves the angle of the path named PATH_NAME relative to the coordinate system.
• POINT_NAME.x: Fetches the absolute X-coordinate of the point named POINT_NAME.
• POINT_NAME.y: Fetches the absolute Y-coordinate of the point named POINT_NAME.
• PATH_NAME.POINT_NAME.angle: Retrieves the angle of a specific point on a path in the path’s direction.

🌟 Benefits of Using Formulas

• Efficiency: Automate repetitive calculations and adjustments.
• Consistency: Maintain precise relationships between elements in your design.
• Adaptability: Easily update your patterns by modifying inputs or constraints.

🚀 Example Use Cases

• Length Adjustment: Automatically calculate the length of one path as a multiple of another (e.g., PATH1.length * 1.5).
• Positioning: Define a point’s position dynamically based on other points (e.g., PATH1.length + 10).
• Symmetry: Mirror angles or lengths across different parts of your pattern.

Formulas transform SeamScape into a truly dynamic pattern design tool, enabling complex and adaptable creations with ease.
