Options to edit LineString items

Before proceeding with this topic, ensure you are familiar with status options (editable, hittable, visible and invisible). See also Overlays Dialogs.

Select the graphics before beginning to edit them.

There are a range of editing tools in SIS Desktop 9.1. Have a look at these options.

Option	Description
Join LineStrings	Joins single or multiple LineString items.
Join	Joins two LineString items with an additional LineString item segment.
Trim/Extend	Shortens or extends LineString item segments without joining them to other LineString items.
Trim and Join	Joins two LineString items by extending or trimming them so they meet, joining them into a single polyline.
Append	Allows you to continue a LineString item you constructed earlier, carrying it on to draw further LineString item segments. The original LineString item and the new LineString item all become part of a single LineString item.
Reprofile LineString	Allows you to redefine a selected path of a LineString item, automatically deleting the old path and connecting the new path into the polyline. It can also be used with topology, see What is Topology?
Delete Path	Deletes a path (a path is any part of a LineString item between two user-selected points.) These points may or may not coincide with vertices.
Move Path	Moves a selected path to a new position. New LineString items are created connecting the path to its original adjacent vertices.
Delete Segment	Deletes a segment from a LineString item.
Move Segment	Moves a selected LineString item segment to a new chosen position. The LineString item segment remains joined to its original adjacent vertices by two new LineString item segments.
Facet	Replaces curved geometry segments with shorter straight segments.
Chamfer	Creates straight LineString chamfers at the vertices of polylines.
Fillet	Creates a circular blend at a vertex on a polyline.
Smooth Midpoint	Smoothes the geometry of the selected items, keeping segment mid-points fixed. The resulting smooth items will be made up of joined Bezier curves. Use Smooth Midpoint to have a new curved LineString item created, which touches the original LineString item at the midpoints of its segments.
Smooth Vertex	Smoothes the geometry of the selected items, keeping vertices fixed. The resulting smooth items are made up of joined Bezier curves. Use Smooth Vertex to have the new curved LineString item touch the original at its vertices
Split	Breaks one LineString item into two LineString items.
Slice	Slices through Polygon items, cutting them into pieces.
Snip Inside	Snips away portions of the selected items inside a Polygon.
Snip Outside	Snips away portions of the selected items outside a Polygon.
