30 degree's and 30 degrees
An isometric is more specific
an isometric sketch is a 3D drawing of different regular prisms that are often drawn on isometric dot paper isometric sketches are useful for planing enginering basic items.
Isometric drawings and shapes are angled to 30 degrees.
These principles are usually taught in a drafting class, but may be taught in advanced art as well. Orthographic views may be drawn out on a page to show top, front and side views of an isometric drawing that is also drawn on the page as well. This is a basic drafting design setup.
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.
An isometric view necessarily should have two side views and either top or bottom view incorporated to be drawn in a single drawing. In order to represent top 0r bottom view a 30 degree angle from horizontal will be established as an inclined plane. Hence where the circle has to appear is important. Any how in order to get a circle in an isometric view an oval or elliptical form should be present in any one of the first angle or third angle views.
Isometric drawings, 3-D representations, are drawn on an angle to the parallel to show how the finished product should look. All dimensions should be the same as if drawn flat (2 dimensional).

an isometric sketch is a 3D drawing of different regular prisms that are often drawn on isometric dot paper isometric sketches are useful for planing enginering basic items.
Isometric drawings are drawn to the same scale along all three axes (x,y,z) so are useful for giving a sense of relative dimensions, and three dimensional scale. Measurements can also be taken from the drawings for items that lie along or parallel to an axis.
1.)Oblique sketch has a more focus on the front side of an object or the face while isometric sketch focuses on the edge of an object. 2.)Oblique sketch drawn usually using the 45-degrees angle to render the third dimensions while isometric sketch drawn using 30 degrees angles.
Isometric drawings and shapes are angled to 30 degrees.
Two popular methods for drawing 3d objects on paper are Oblique and Isometric projections. In Oblique, the front of the object is drawn like you are looking straight at it. The top and bottom recede away at an angle (usually 45° from horizontal). In Isometric, there are vertical lines, and lines at 30° from horizontal in either direction. Both of these methods can be drawn by hand or with the aid of T-square and triangle, or special gridded paper. See related links for more information.
A form of three-dimensional projection in which all of the principal planes are drawn parallel to corresponding established axes and at true dimensions; horizontals usually are drawn at 30° from the normal horizontal axes; verticals remain parallel to the normal vertical axis.
In first angle auto graphic projection the planed, view is drawn exactly below the front elevation. What is viewed from the left is drawn from the right side of the front, it is drawn in the 1st angle and 3rd angle.
One disadvantage of using isometric drawings is that they can sometimes distort the true dimensions of an object, making it challenging to accurately represent the size and proportions of the object. Additionally, isometric drawings can be more complex to create compared to other types of technical drawings, such as orthographic projections. Lastly, isometric drawings may not always provide all the necessary information needed for precise engineering or design purposes, as they do not show all sides and angles of an object simultaneously.
These principles are usually taught in a drafting class, but may be taught in advanced art as well. Orthographic views may be drawn out on a page to show top, front and side views of an isometric drawing that is also drawn on the page as well. This is a basic drafting design setup.
