Introduction
The idea of this QGIS plugin is to subsume different tools useful
during digitizing sessions. Everybody is welcome to add their tools
to this collection.
Currently the following tools are contained:
- SplitMultipart: Splits multipart features into singlepart in the
active editable layer; taken from Alexandre Neto’s SplitMultipart
plugin.
- Cutter: cut out from active editable layer with selected polygon from
another layer
- Splitter: split selected features in active editable layer with
selected line from another layer
- MoveNodeByArea: modifies a selected polygon, by selecting a stable
node (red) and a node to move (blue). The plugin moves the
second node automatically (along a stable side) to achieve the polygon
area as provided by the user
- MoveSideByDistance: modifies a selected polygon, by selecting a single
polygon side (segment) and by providing a distance to move the selected side.
- MoveSideByArea: modifies a selected polygon, by selecting a single
polygon side (segment). The plugin moves the second node automatically
to achieve the polygon area as requested by the user. This tool has two
options: (1) moving selected side by keeping it’s length (fixed) and
(2) moving selected side along the direction of the two touching sides,
forming a trapezoid along the process. The second option modifies the
selected side length (variable).
- MedianLine: creates median polylines between adjacent polygons. This is
done by selecting nodes in turns, on corresponding sides of adjacent polygons.
This has to be done in the following way: the first point is selected on side 1
(red marker), the second point on side 2 (blue marker), the third point is the
next vertex of side 1 (red marker) the forth point is the next vertex of side 2
(blue marker) etc, until full coverage of both sides of opposite polygons.
The same number of clicks has to be performed on both sides, but clicking on
the same vertex is permitted (the tool will ignore douplicate points).
When finished, right click and the median line will be created on a new polyline layer.
Planned/discussed tools can be found here http://osgeo-org.1560.x6.nabble.com/more-advanced-editing-tools-td5019552.html
This plugin is supposed to have no CAD-like tools which should go into
the CADTools plugin, see also http://osgeo-org.1560.x6.nabble.com/Make-QGIS-interact-with-LibreCAD-td5048565.html

CADTools from where I took some code for the management of the plugin.
