Perspective Projection #

A method of depicting a 3D object in 2D views, with converging lines representing the object's edges and surfaces.

Plane #

A flat, two-dimensional surface.

Plan View #

A view of a 3D object from directly above, showing the top surface and any features that are visible from that angle.

Polyline #

A connected series of straight line segments or arcs.

Projection Line #

A line used to connect points or features on different views of a 3D object.

The distance from the center of a circle to its edge.

Revolution #

The process of rotating a 2D shape around an axis to create a 3D object.

Scale #

The ratio of a measurement on a technical drawing to the actual size of the object or feature being represented.

Section View #

A view of a 3D object that shows the interior or cross-section of the object, created by cutting through it with a plane.

Shape #

The form, contour, or configuration of an object or surface.

Sketch #

A rough, preliminary drawing used to explore or communicate ideas.
