An isometric plane is a plane that intersects both the front and side views of a 3D object at the same angle. This means that the plane cuts the object into two identical parts, regardless of the viewpoint.
Imagine a flat sheet of paper folded into a triangle. This is a 2D isometric plane projecting a 3D object onto the plane.
Isometric planes have a number of important properties:
Parallel lines in the 3D object are parallel in the 2D projection.
Consecutive lines in the 3D object are perpendicular in the 2D projection.
The distance from a point in the 3D object to the plane is constant in the 2D projection.
Isometric planes are commonly used in various engineering graphics applications, such as:
Creating axonometric drawings: axonometrics represent objects with their true dimensions and proportions based on their 3D measurements.
Creating orthographic drawings: orthographic drawings are created using isometric projection, where parallel lines are drawn at equal distances.
Creating perspective drawings: perspective drawings use isometric projection to show depth and perspective.
Examples:
A plane through a point and perpendicular to a line in the 3D object.
The plane of a cylinder.
The plane of a cone.
