always 30 degrees
thrid angle projection is officially used in Australia, for a fact, not lying!!
Firstly Draw a pentagon and enclose it in a square. Then draw an isometric scale. With isometric reading draw the square first on 120degree axis, reduce the pentagon sides on isometric scale and plot it on the isometric square
Usually 60 degrees.
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.
First angle projection and third angle projection are two methods of orthographic projection used in technical drawings. In first angle projection, the object is placed in the first quadrant, meaning the view is projected onto the plane behind the object, resulting in the top view appearing below the front view. In contrast, third angle projection places the object in the third quadrant, with the views projected onto the planes in front of the object, making the top view appear above the front view. These conventions are used to standardize how drawings are interpreted, with first angle commonly used in Europe and third angle in the United States.
It is 3D view at an angle and diminishing into the distance.
isometric
Isometric projection is another way of saying 3D. With isometric projection things are drawn on a two dimensional surface to show how they would look in 3D.

I think both are same. There is difference between isometric view and isometric drawing that is of size.
No, a multiview projection is used for developing a multiview drawing. Multiview projections are orthographic projection where the object is behind the plane of projection, and is oriented such that only two of its dimensions are shown.
tae
isometric drawing create the illusion of 3 dimension by drawing the depth of the object on the both side.. in isometric drawing they are both set on the 30 degree angle..
the angkle of projection is an angle and the projection
Isometric~!!
first angle projection and third angle projection.
We convert inches to mm sizes. 1 inch = 25.4 mm
