3.1 Coordinates

Unlike 4D Draw, 4D CAD follows mathematical conventions for coordinates

• positive X-coordinates extend to the right (the positive X-axis)
• negative X-coordinates extend to the left (the negative X-axis)
• positive Y-coordinates extend to the top (the positive Y-axis)
• negative Y-coordinates extend to the bottom (the negative Y-axis).

4D CAD is two-dimensional (there are no 3D features).

Coordinates are 64-bit floating-point values, see Unit and scale.

This manual uses the . for decimal fractions The notation for a point with X-coordinate 1.23 and Y-coordinate −4.56 is (1.23,−4.56).
