Creates a mirror image
of the given object about a plane.
Signature
VBA : RetVal =
object.Mirror3D(Point1, Point2, Point3)
VL : RetVal =
(vla-Mirror3D object Point1 Point2 Point3)
(vla-Mirror3D obj fpoint spoint
tpoint)
-
Object :
All Drawing Objects
The object or objects this method applies to.
-
Point1 : Variant
(three-element array of doubles); input-only
The 3D WCS coordinates specifying the first point of the mirror
plane.
-
Point2 : Variant
(three-element array of doubles); input-only
The 3D WCS coordinates specifying the second point of the mirror
plane.
-
Point3 : Variant
(three-element array of doubles); input-only
The 3D WCS coordinates specifying the third point of the mirror
plane.
-
RetVal : Mirrored
object
This object can be one of any Drawing Objects.
Remarks
AutoCAD checks to see if
the object to be copied owns any other object. If it does, it performs a
copy on those objects as well. The process continues until all owned
objects have been copied.
NOTE
You cannot execute this method while simultaneously iterating through a
collection. An iteration will open the work space for a read-only
operation, while this method attempts to perform a read-write operation.
Complete any iteration before you call this method.
AttributeReference:
You should not attempt to use this method on AttributeReference objects.
AttributeReference objects inherit this method because they are one of
the drawing objects, however, it is not feasible to perform this
operation on an attribute reference.
Example :
(defun c:al-mirror3d ()
(vl-load-com)
(setq util (vla-get-utility
(vla-get-activedocument
(vlax-get-acad-object))))
(vla-getentity util 'obj 'ip "\nSelect Object: ")
(setq fpoint (vla-getpoint util nil
"\nSpecify first point of mirror line: "))
(setq spoint (vla-getpoint util fpoint
"\nSpecify second point of mirror line: "))
(setq tpoint (vla-getpoint util fpoint
"\nSpecify third point of mirror line: "))
(setq newobj (vla-Mirror3D obj fpoint spoint tpoint))
(princ)
);defun
