In the first angle projection, the object is placed in the 1st quadrant. The object is positioned at the front of a vertical plane and top of the horizontal plane. First angle projection is widely used in India and European countries. The object is placed between the observer and projection planes.

What is isometric projection in AutoCAD?

Isometric drawing in AutoCAD, tutorial with video. Isometric drawings are not actual 3D drawings, they are made with 2D geometries but they appear like 3D. Isometric drawing in AutoCAD can be made by tilting viewing angle to 30 degrees for all of its sides in the 2D plane.

What are the 4 orthographic views?

Orthographic drawings are also known as multiviews. The most commonly used views are top, front, and right side. You can imagine it as positioning yourself directly in front, above, or to the right of an object and drawing only what you can see.

What is 3rd Angle Projection?

3rd Angle project is where the 3D object is seen to be in the 3rd quadrant. It is positioned below and behind the viewing planes, the planes are transparent, and each view is pulled onto the plane closest to it. The front plane of projection is seen to be between the observer and the object.
