Trimming items

1. Select items to trim from and press Enter:
• Indicate one or more base items from where you want to trim.
• Press Enter when you are ready with indicating the base items.
• You can press Enter without indicating items to select all the present 2D-items in the drawing.
• After pressing Enter the selected base items are set to the pen number 30 for a better recognition.
2. Select items to trim or Shift-select to extend:
• Indicate one or more items to trim. The pointed item parts are trimmed immediately.
• In case of dragging a conflict box or a clump box, the first corner point defines the parts from where the items are trimmed.
• If you want to extend items to the same base item collection, point to the item you want to extend while you are pressing Shift.
• It is also possible to trim the items which belong to the base item collection.

Note: For trimming a line segment without indicating base items you can use the Modify > Lines > Move End Point function.
