Specify a point
The angle you specify will lock the cursor, overriding Grid Snap, Ortho mode,
and PolarSnap. Coordinate entry and object snaps have precedence over an
angle override.
Combine or Offset Points and Coordinates
To specify a new point location, you can combine coordinate values from
several points or you can specify offsets from existing objects.
Combine Coordinate Values (Coordinate Filters)
You can use coordinate filters to extract one coordinate value at a time from
locations on existing objects.
Coordinate filters specify a new coordinate location by using the X value from
one location, the Y value of a second location, and, for 3D coordinates, the
Z value of a third location. When used with object snaps, coordinate filters
extract coordinate values from an existing object.
Coordinate filters are commonly used to locate the center of a rectangle and
to locate the projection of a 3D point on the XY plane of the UCS.
To specify a filter at the Command prompt, enter a period and one or more
of the letters X, Y, and Z. The next entry is limited to a specific coordinate
value.
Example: Use of Coordinate Filters in 2D
In the following illustration, the hole in the holding plate was centered in the
rectangle by extracting the X,Y coordinates from the midpoints of the plate's
horizontal and vertical line segments.
