Point filters
When we want to specify a point but decompose it step-by-step, that is, separate its
coordinates based on different locations, we may use filters. When prompting for a
point, we access filters by digitizing the X, Y, or Z axes for individual coordinates, or
XY, YZ, or ZX for pairs of coordinates. Another way is from the osnap menu,
CTRL
+ mouse right-click, and then
Point Filters
. AutoCAD requests for the remaining co-
ordinates until the completion of point definition.
Imagine that we want to specify a point, for instance, the center of a circle, where its
X coordinate is given by the midpoint of an edge, its y coordinate is the midpoint of
another edge, and finally its Z coordinate is any point on a top face. Assuming that
Midpoint osnap is predefined, the dialog should be:
