Element Replacement
When using the command “RL: Replace Element”, the target element should not be a child of the source
one. Otherwise, a message is output about the encountered recursion.
In the next example, the “Line 2” is constructed relative to the base
line, “Line 1”. In turn, the lines “Line 3” and “Line 4” are constructed
relative to the “Line 2”. A circle is created with the center at the
intersection between the “Line 2” and the horizontal line in such a way,
that it intersects the “Line 3” and not the “Line 4”.
An attempt to replace the “Line 1” by the “Line 2” in this model causes
the message about recursion.
The command may also fail when some drawing element position cannot be defined relative to the target
element.
For example, when creating the drawing of the above example, one of the nodes was defined as the node at
the intersection between the circle and the “Line 3”. An attempt to replace the “Line 3” by the “Line 4” will
cause an error message, since the system will not be able to define the position of this node after the
replacement.
