Here is the Command prompt sequence:
Command: circle
Specify center point for circle or [3P/2P/Ttr (tangent tangent
radius)]: .x
of: mid
of: Select the horizontal line on the lower edge of the holding plate
of: (need YZ): mid
of: Select the vertical line on the left side of the holding plate
of: Diameter/<Radius> Specify the radius of the hole
Coordinate filters work only when the program prompts you for a point. If
you try to use a coordinate filter at the Command prompt, you see an error
message.
Example: Use of Coordinate Filters in 3D
This example shows how to use coordinate filters to create a point object at
the center (centroid) of a 3D object. Hidden lines have been removed for
clarity. The X value of the new point is extracted from the first location
specified, the Y value from the second location, and the Z value from the
third. The three values are combined to form the coordinate values of the new
point.
Command: point
Point: .x
of mid
of select object (1)
(need YZ): .y
of mid
of select object (2)
(need Z): mid
of select object (3)
