GEOMETRY POINT INTERSECT pnam shnm1 [shnm2] [shnm3] or lnam1 lnam2

        

This command positions an existing point to be on the intersection of up to three shapes.


pnam = name of a point that has been defined earlier. The existing coordinates are used as a
first approximation. If the approximation is too bad, the INTERSECT command
may fail to calculate the correct coordinates of the point.
/PICK and a cursor hit to select an existing point to be moved.
shnm = names of up to three shapes which define the coordinates of the point.
lnam = or names of up to two lines which define the coordinates of the point.

The position of the point will be dependent on the shapes referenced in the command. If the definition of a referenced shape changes then the position of the point will also change.
