Right side in the drawing is the top-view which can be mirror about the X or Y-axis. While the side-view(left on sketch), can be mirror X-axis. Take special note of the Tolerance and the reference surface.

Top view consist of symmetry about the x or Y-axis. A quarter-view or Half-view could be drown and mirror about the X or Y-axis respectively. The side is symmetry about the X-axis. According to the sketch, the right sketch is consider a top-view while the left-view is consider a side-view. Notice that the part contain tolerant that must consider during the design.

This is an assembly, it consist of four different part coordinated together. Different constraint were use to assembly the part. The assembly component can be seen bellow the assembly in green.

Top view consist of symmetry about the x or Y-axis. A quarter-view or Half-view could be drown and mirror about the X or Y-axis respectively. The side is symmetry about the X-axis. According to the sketch, the right sketch is consider a top-view while the left-view is consider a side-view. Notice that the part contain tolerant that must consider during the design.

Just the top-view and the side-view. Notice that this part contain a Key-way. Mirroring tool can be use on the top and side view about the X-axis.

This part consist of an Auxiliary view. True Dimension of an auxiliary can only be seen by extrapolation of side, top or right view.

This part consist of an Auxiliary view. True Dimension of an auxiliary can only be seen by extrapolation of side, top or right view.

Only the structure view are available. No dimensions. From the sketch the structure can be assume. This part was used in the Bearing assembly above, check for more information.

The top-view give you the detail views of the top 2-D dimension. The section A-A give more information about the dept(thickness). In AutoCAD 217, the top view was drown, using construction line, the side view was extrapolated.

Top and side view of the 2-D sketch give information about the part creation. Considering the top view as symmetrical, design could be more more easier. Drawing a quarter top and mirroring about the X and Y-axis.
