You can use the 3D Pointer 
to point to a location in all of the drawing views in drawing files. When you use the 3D Pointer, a linked set of crosshairs appears in each of the drawing views. For example, you can place the crosshairs on an edge in one view and the crosshairs in the other views point to the same edge.
The crosshairs colors (which cannot be changed) indicate the following:
| Color |
Axis |
|---|
| Red |
X-Axis (perpendicular to YZ plane) |
| Blue |
Y-Axis (perpendicular to XZ plane) |
| Green |
Z-Axis (perpendicular to XY plane) |
