Supports switching between two grid types: Cartesian coordinate system, polar coordinate system
You can also set whether the grid in the canvas is grid lines, grid points, or no grid display.
The Cartesian coordinate system is the most commonly used, and ordinary boards can use this coordinate system to complete the design.
The polar coordinate system is a coordinate system that takes the center of the circle as the origin and expands outward in a fan shape. It is generally used when designing annular boards and layouts.
