I am assuming that you are in a three dimensional world. Then the three planes of projection would be the xy plane, the xz plane, and the yz plane.
In a first angle projection, the object stands in between the observer and the plane of projection. In a third angle project, the object and the plane of projection is interchanged.
it is physically the projection or shadow of a line on a plane...
First angle projection places the object between the observer and the plane of projection, meaning the top view is below the front view, and the right side view is on the left side of the front view. In contrast, third angle projection positions the object behind the projection plane, resulting in the top view being above the front view and the right side view appearing on the right side of the front view. To interpret these drawings, one should remember the placement of views relative to each other based on the projection method used. Familiarity with these conventions helps in accurately visualizing the three-dimensional object from its two-dimensional representations.
the answer is... -OBLIQUE -ISOMETRIC -PERSPECTIVE OR -DIAMETRIC
First angle projection is commonly used in Europe and involves positioning the object between the observer and the projection plane, resulting in the top view appearing below the front view. In contrast, third angle projection, prevalent in the United States, places the projection plane between the observer and the object, making the top view appear above the front view. To interpret these drawings, one should recognize the orientation of views and how they relate to the object's spatial arrangement, ensuring accurate visualization and understanding of dimensions and features. Always check the symbols indicating which projection method is used to avoid confusion.
3D projection is any method of mapping three-dimensional points to a two-dimensional plane. It is used for certain types of engineering drawings.
In a first angle projection, the object stands in between the observer and the plane of projection. In a third angle project, the object and the plane of projection is interchanged.
A map projection designed on a flat plane touching the globe at one point such as the north or South Pole.

The Fischer projection is used to illustrate the structure of linear monosaccharides. A vertical bond line at a given carbon centre shows that the bond is pointing into the plane while a horizontal bond line shows that the bond is pointing out of the plane.
1. Top view is directly over the front view. 2. Side view is inline horizontally with either top view or front view. 3. A line parallel to a plane of projection will be projected on that plane as a line. 4. A surface parallel to a plane of projection will be projected on that plane 5. A line perpendicular to a plane of projection will be projected on that plane as a point. 6. A surface perpendicular to a plane of projection will be projected on that plane as line.
Mercator Projection, Interrupted Projection, Robinson Projection
the importance of Orthographic drawing is a basic understanding of presentation drawing, wherin 3 main views of an object are presented in correct dimension of the height, width and depth.
Auxiliary views utilize an additional projection plane other than the common planes in a multiview. Since the features of an object need to show the true shape and size of the object, the projection plane must be parallel to the object surface. Therefore, any surface that is not in line with the three major axis needs its own projection plane to show the features correctly.

A Winkle Tribal map projection is a modified azimuthal map projection. This is one of three projection.
