PCD Calculator – Coordinates

PCD Calculator (Circular Coordinate Tool) is a professional calculator app for engineers and designers who need PCD calculation, hole coordinate calculation, flange hole patterns, and bolt pattern coordinates.
It is optimized for circular pattern coordinates, machining drawings, mechanical design, and flange layout design.

PCD Calculator (Circular Coordinate Tool) visually displays circular patterns based on PCD and calculates the coordinates (X/Y) of each hole accurately.
It is designed not only for bolt patterns but also for flange hole layouts, machining and drawing references, and various circular coordinate calculations.

Key Features
- PCD calculation and circular pattern visualization
- Graphic display of PCD-based hole patterns
- Automatic calculation of hole coordinates (X/Y)
- Instant display of selected hole coordinates
- Setting for number of holes (N), start angle, and reference angle
- Origin (X/Y) setting to support various coordinate systems
- Supports flange holes, bolt patterns, and circular array coordinate calculations

Multilingual Support
- Korean / English language switching

Use Cases
- Visually check PCD-based hole layouts and organize coordinates
- Calculate hole positions for flanges and circular patterns
- Reference coordinates for machining and technical drawings

Notice
- This app is intended for calculation and reference purposes only.
- When applying to actual design or machining, always consider tolerances, measurement errors, and working conditions.
