Connect Linework
Connect Linework is used to merge a network of connected lines into one element by using a fence. The connected linework could be any number of contiguous linear elements that share common endpoints in a consecutive manner.
Note: This command is
influenced by the Consider Z setting in the Preferences dialog. If the Consider
Z setting is not enabled, all connected elements will be placed at elevation 0.
Elements will be considered connected if their X and Y vertices are the same,
but possibly not their Z values. Meaning they appear connected if viewed from
the top view but disconnected if viewed from the side. If the Consider Z
setting is enabled, then elements must be share endpoints exactly in order to
be connected.
