The Isometric Snap/Grid mode helps you create 2D isometric images that represent 3D objects.
The Isometric Snap/Grid mode helps you create 2D images that represent 3D objects. By setting the Isometric Snap/Grid, you can easily align objects along one of three isometric planes; however, although the isometric drawing appears to be 3D, it is actually a 2D representation. Therefore, you cannot expect to extract 3D distances and areas, display objects from different viewpoints, or remove hidden lines automatically.
Simulate a 3D object from a particular viewpoint by aligning along three major axes.
