The measuring line or the line of heights is the trace or the line of intersection with the picture plane, of the ____________ plane containing the point or points whose heights are to be determined.

Oblique projection is a type of parallel projection that produces two-dimensional images of three-dimensional objects. In an oblique projection, the projection lines are parallel to each other, but they meet the surface at an angle other than 90 degrees. 

In a perspective projection, the projection lines radiate from a single point. Perspective projection is a type of rendering that approximates the images of three-dimensional objects on a two-dimensional surface. It is also known as perspective view, perspective drawing, or simply perspective. 

Here are some more details about oblique and perspective projection:
Oblique projection: The observer is considered to be at infinity, and the plane of projection is parallel to the front surface of the object. Commonly used oblique projections orient the projection plane to be perpendicular to a coordinate axis, while moving the lines of sight to intersect two additional sides of the object.
Perspective projection: It graphically approximates the images of three-dimensional objects on a two-dimensional surface to approximate actual visual perception.
