The Map Editing group on the Object Operation tab is used to edit various types of Geometry on the map, and Application provides the following Geometry Object Editing operations. These operations can only be performed when the current Vector Layer is editable.

• Paste: It is used to copy the contents on the clipboard to the editable Vector Layer of the same type.

  When the current layer is editable, click the Paste button (or use the shortcut key Ctrl + V) to save the Geometry currently saved on the clipboard in the current layer, and the attribute record of the pasted object will be appended to the end of the attribute table of the pasted Dataset.

  Caution:

  There must be something on

  the clipboard that you can paste.

  A

  copied object can only be pasted into a Dataset that can support it. Dataset descriptions of point, line and surface objects that support pasting are as follows:

  • Point objects support pasting into points and CAD Dataset, or Layout.
  • The line object can be pasted into a point, line, surface, CAD Dataset or Layout. When the line object is pasted into the Point Dataset, the line object will automatically Convert to Point the object, that is, the node of the line object will be directly Convert to Point the object; When a line object is pasted into a Region Dataset, a line object that is not a straight line is automatically converted to a face object. If the line object is closed, the line is the boundary of the face object. If the line object is not closed, the line object is converted to a face object after Connect End-to-End.
  • Face objects support pasting into lines, faces, CAD Dataset, or Layout. When a face object is pasted into a Line Dataset, its boundary lines automatically Convert to Line the object.

  Copied object	Dataset Type pasted into
  	Point Dataset	Line Dataset	Region Dataset	Text Dataset	CAD Dataset	Layout
  Point object	Support	Not supported	Not supported	Not supported	Support	Support
  Line object	Support	Support	Support	Not supported	Support	Support
  Face object	Not supported	Support	Support	Not supported	Support	Support
  Text	Not supported	Not supported	Not supported	Support	Support	Support

• Clip: Used to clip the selected Geometry and save it to the clipboard.

  When the current layer is editable, select one or more Geometry (auxiliary Shift key), and click the Clip button (or use the shortcut key Ctrl + X) to clip the selected Geometry from the original Dataset and save it to the clipboard.

• Copy: Used to copy the selected Geometry and save it to the clipboard.

  When the current layer is editable, select one or more Geometry (auxiliary Shift key), and click the Copy button (or use the shortcut key Ctrl + C) to copy the selected Geometry and save it to the clipboard.

• Multi-layer Editing: Used to control the editable state of multi-layers in the current Map. See the Turn on layer editing for more information.
• Undo: For Undo the last operation.

  With the current layer editable, click the Undo button (or Ctrl + Z) to Undo the last operation.

  . Undo is only available when

  Geometry has been edited.

• Redo is used to resume the previous operation.

  When the current layer is editable, click the Redo button (or use the shortcut key Ctrl + Y) to Return to the status before the last undo operation.

  . The Redo button is available

  only after an undo operation has been performed.

• Delete: Use to delete one or more Select Objects.

  When the current layer is editable and one or more objects are selected, click Delete to delete the selected objects.

• Style Brush: Used to assign an object's style to another object. For more information about style brushes, see Style brush .
• Attribute Brush: Used to assign some or all of an object's editable fields and their values to other objects. For more information about attribute brushes, see Attribute brush .
