§31. Projections with numerical marks

Lecture



The essence of the projection method with numerical marks is that any point in space is projected orthogonally onto one horizontal plane, called the plane of the zero level. The position of a point relative to this plane is determined by the numerical mark affixed to the letter of the projection of the point and represents the number of units of distance from the point to the plane of the projections.
