ET Polyline:

NOTES: EditTools allows user control over the way the attributes are updated when   polylines are split or merged. In order to ensure that the attributes are updated appropriately go to THEME/PROPERTIES/EDITING and adjust the values in the Attribute Updating panel. IMPORTANT See discussion about Fuzzy Tolerance The UNITS used are the map units of the current VIEW Minimize/Maximize button is provided to allow the user to free some screen space when the global functions are not in use. New Features: Export Nodes function available directly on ET Polyline dialog. Can be used out of an editing session.

• Current Theme Button - Sets the theme to be edited. The label of this Button shows the name of current theme
• Fuzzy Tolerance Button - see Discussion opens the Fuzzy Tolerance Dialog  the user can specify the tolerance to be used. The value of the tolerance should be between MIN and Max values shown on the dialog. Reset Buttons sets the tolerance to the default value. OK Button accepts the user input.
• Start Editing Button - toggles editing the Current Theme
• Save Button - Saves the edits
• Save As Button - Saves the Current Theme as new theme. The new theme becomes Current
• Show Edit Tools Button - toggles Edit Tools Dialog
• Clean - Introduces Clean Dialog. Performs check for multipart Polylines and if present converts them to single part ones. Saves the single part theme to the disk. (Always keep a copy of your original theme.). See Clean Dialog
• G__D__S__F - Introduces Generalize__Densify__Smooth__Flip   Dialog
• Edge Match - Opens Edge Match Dialog
• Adjust - Introduces Adjust Dialog
• Renode - Creates unique ID numbers for polylines and renumbers the nodes for each polyline. If not available, creates three new fields ET_Id, ET_FNode, ET_TNode and populates them.
• Build Polygons - Enabled only when the current theme is not edited. Builds polygon theme from the current theme.
  • The theme must be clean.
  • All the dangling polylines will be considered as non Polygon elements and will be excluded.
  • If a point theme (Label points) with attributes is available it can be used to attach these attributes to the newly created polygon theme.
  • Each polygon should have ONE and only ONE label.
• Split with theme - User selects a split theme(polygon, polyline or point). The selected features of the split theme are used to split the features of the current edit theme. The attributes are updated according user defined attribute split rules. NOTE: If the split theme is of Point type a snap tolerance is required.
• Split In Vertices - Splits selected polylines (all polylines if there is no selection) in all the vertices. Converts the polylines to single segmented polylines (lines). The attributes are updated according to the user defined attribute update rules.
• Polyline To Point - Export polyline theme to point theme. Exports the selected features only.
  • Export nodes, vertices, center of segments or the middle point of the polylines.
  • Write the segment bearings to the point attribute table. If export Vertices option is selected the user have to select the vertex (start or end of the polyline segment) to be used for assigning the segment bearing to the point.

Start Vertex	End Vertex

Allows rotating the point symbols with the bearing of the pertaining line segments

• Attributes from Points - allows transferring the attributes from a point theme to the current polyline theme. The user has to input search tolerance. The attributes of the closest point to a specific polyline (within the search tolerance) are transferred. If the tolerance is too big the attributes of a point might be attached to several polylines and the results might be undesired. Very useful when working with CAD data with label points.
• COGO - initiates a Cogo session. If current theme is editable the COGO polyline will be added to the theme else a graphic shape will be drawn. See ET Cogo for details.
