Command Modifiers
Overview of Command Modifiers
You can use command modifiers to help you locate points or select objects
while a command is in progress. Use the Coordinate Filter, Direct Distance
Entry, From, MTP, and Tracking command modifiers at any prompt that requires
point specification. Use the Selection Mode command modifiers at any prompt
that requires object selection.
Coordinate Filters (Command Modifier)
Combines X, Y, and Z values from different points to specify a single point
Command entry: Enter .x, .y, .xy, .xz, or .yz
At any prompt for locating a point, you can enter point filters to specify a single
coordinate by extracting the X, Y, and Z values of several points. In the following
example, the start point for the line has a coordinate constructed from the X
value of the midpoint of the first object you select, with the Y and Z values of
the midpoint of the second object you select.
