Answer :
Final answer:
Orthographic drawings are 2D representations of a 3D object, while isometric drawings are 3D representations that show all three dimensions equally. Isometric drawings are created by drawing parallel lines at constant angles from the orthographic views. They provide a 3D representation of an object, while orthographic drawings accurately represent the object's dimensions and details in 2D.
Explanation:
Orthographic drawings, also known as orthogonal projections, are 2D representations of a 3D object created using views from different directions. Isometric drawings, on the other hand, are 3D representations of an object that show all three dimensions equally. Isometric drawings are created by drawing parallel lines at constant angles from the orthographic views. The angles are usually 30 degrees, resulting in equal spacing between the lines in the isometric drawing.
For example, if you have a rectangular block in an orthographic drawing with one side facing vertically upward in the coordinate system, the corresponding line in the isometric drawing would be drawn at a 30-degree angle from the horizontal plane, moving upward and to the right side of the coordinate system.
It's important to note that isometric drawings are useful for providing a 3D representation of an object, while orthographic drawings are used to accurately represent the object's dimensions and details in 2D.
