30° 30° Isometric Fundamentals All angles between the axonometric axes are equal 360° / 3 axes = 120° between axes Vertical axis remains vertical Horizontal axes (Width and Depth) drawn 30° above horizontal 2
Isometric View from Orthographic Views An isometric view of an object is created by rotating the object 45° about a vertical axis, then tilting the object forward until the body diagonal appears as a point in the front view.
