Edit MultiLine vertices, cuts / breaks, and intersections
  | 
Command: MLEdit  | 
This command opens the MultiLine Edit dialog.
  | 
There are several utilities provided to modify multiline crossings, connections and vertex sequence. 
 We are very sorry for this inconvenience !  | 
  | 
Closed Cross creates a "closed cross" intersection from 2 selected multilines - the first selected multiline has priority.  | 
  | 
Open Cross creates an "open cross" intersection from 2 selected multilines - for the second multiline, only the outer-most lines will get breaks.  | 
  | 
Merged creates an "merged cross" intersection from 2 selected multilines - both multilines have same priority.  | 
  | 
Closed Tee creates a "closed tee" intersection - the first multiline is trimmed resp. extended to the second multiline.  | 
  | 
Open Tee creates an "open tee" intersection - the first multiline is trimmed resp. extended to the second multiline, which is also opened.  | 
  | 
Merged Tee creates a "merged tee" intersection - the first multiline is trimmed resp. extended to the second multiline.  | 
  | 
Corner Joint creates a "corner joint" intersection - the elements of both multilines are trimmed resp. extended to their intersections.  | 
  | 
Add Vertex inserts a new vertex into the multiline.  | 
  | 
Remove Vertex removes a vertex from the multiline.  | 
  | 
Cut Single inserts a cut into selected element of a multiline.  | 
  | 
Cut All inserts a cut into all elements of a multiline.  | 
  | 
Weld All removes all cuts from all multiline segments.  |
