Merge Closed Polylines

This command combines two closed polylines that share a common boundary to create a single closed polyline. For example, this command can be used to merge a polyline for a lot that is too small with a polyline for a neighboring lot. There are two methods for merging. One method is to pick the two polylines to merge. The other method takes an area size and selection set of polylines and merges all the polylines with an area smaller than the specified amount.
