OSMODE
Turns on various entity snap settings using a combination of bit codes.
0 = Clear entity snaps
1 = Endpoint snap
2 = Midpoint snap
4 = Center snap
8 = Point snap
16 = Quadrant snap
32 = Intersection snap
64 = Insertion point snap
128 = Perpendicular snap
256 = Tangent snap
512 = Nearest snap
1024 = Geometric Center snap
2048 = Apparent Intersection snap
4096 = Extension snap
8192 = Parallel snap
16384 = Suppresses the current running entity snaps
To activate more than one entity snap at a time, add the bit codes of the entity snaps you want to activate. For example, entering 3 activates both the endpoint snap (bit code 1) and the midpoint snap (bit code 2). Note that you cannot use Intersection Snap and Apparent Intersection Snap at the same time.
