Editing Toolbox
back to Index or to List of Functions
The Editing Toolbox is a collection of tools for editing, generating and modifying geometries on the Layer View. User can make complex drawings from basic elements, such as lines, circles or polygons. Features can be duplicated, modified or rotated
The Editing Toolbox is opened by selecting the Editing Toolbox tool on the Toolbar 
or from the Menubar>View list. To use the Editing Toolbox tools make sure that the working layer is editable.
Note 1: if you open an empty project and select the Editing Toolbox tool on the Toolbar, a new layer is created both in editable and selectable mode.
Selection and Move Tools
These tools allow to select items and to move them
Select feature tool: this allows to select items on the Layer View. This tool is also availble directly on the toolbar
- To select one item left-click on it.
- To select items in an area, left click and hold down drawing a rectangle on the area
- To select differet items in different area, press CTRL key and click on the items.
Select a part of combined features: one or more items in a combined group can be edit using this feature
- To select one item of a group click on it
- To select more items of a group, press CTRL key and click on the items.
Select a hole: a hole in a feature can be selected. This tool is used to modify hole vetices or to move entire hole inside a polygon
Move selected features: This tool is used to move previous selected features, included selected holes.
Drawing Objects Tools
These tools are used to draw items on the Layer View.
Draw a Rectangle allows to draw polygons in the Layer View.
- To draw a Rectangle select Draw a Rectangle tool and draw a box on the Layer View, to stop drawing double click or right-click with mouse on the layer view.
Draw a Polygon allows to draw polygons on the Layer View. It is also used to draw holes on a polygon.
- To draw a Polygon select Draw a Polygon tool and click to place the vertices of the polygon on the Layer View, to stop drawing double click or right-click with mouse on the layer view.
- To draw a hole, select the polygon and use Draw Polygon tool to draw a hole on the top of the former. To stop drawing double click or right-click with mouse on the layer view.
Draw a line allows to draw a linestring on the Layer View. To draw a line select Draw a line tool and click to place the vertices of the line on the Layer View. To stop drawing double click or right-click with mouse on the layer view.
Draw a point allows to draw points on the Layer View. To draw points select Draw a point and left-click to put the points on the Layer View. To stop drawing double click or right-click with mouse on the layer view.
TIP: You can delete the last vertex while you are creating a polygon or linestring clicking on BackSpace key.

OPTIONS...
!http://jump-pilot.sourceforge.net/wikiimages/editing%20toolbox/option/Option.jpg!
Option button allows to customize some drawing option. In _Constraints_ and _Snap/Grid_ options unit is defined by the project unit. It integrates in from OpenJUMP 1.2 the ISA (Integrated Systems Analysis, Inc) tools. Some following notes belong to ISA plugin documentation
Constraints
It allows the users to set drawing consrtraints. For instance, by setting the lenght and incremental angle constraints, the users can draw buidings with exact 90 degree corners with lenght of sides at even 5 metres incremet. Edit selected side allows the users to modify the interior angle and lenght of polygons and lines after they are created
!http://jump-pilot.sourceforge.net/wikiimages/editing%20toolbox/option/3-constraints.jpg!
- _*lenght*_: constraints the lenght of the nearest identified unit. i.e. portion of foot or metre
- _*Incrementasl Angle *_: After drawing the first line, holding the shift will constrain the angle between the current line and the previous line to angle increments established by dividing 360 by the number you place in the box. The control key will constrain the angle to the first line. Shift key will active the command, Ctrl will close it
- _*Angle*_
- _*Constrain to angle*_: box where user can define the constrain angle
- _*Constrain to relative angle*_: After drawing the first line, holding the shift will constrain the subsequent lines to the angle placed in the _Constrain to angle_ box, relative to the previous line.
- _*Constrain to absolute angle*_: While holding the Shift key all lines will be constrained to the angle placed in the _Constrain the angle_ box, relative to zero degree.
Snap/Grid
It defines snapping and grid display
!http://jump-pilot.sourceforge.net/wikiimages/editing%20toolbox/option/4-snap%20grid.jpg!
View/Edit
It actually only prevents editing from invalid geometries
!http://jump-pilot.sourceforge.net/wikiimages/editing%20toolbox/option/5-view%20edit.jpg!
Snap Vertice tool
It customizes menu which inserts vertex in "empty" segments (segments with no vertex)
!http://jump-pilot.sourceforge.net/wikiimages/editing%20toolbox/option/1%20-%20snap%20vertices.jpg!
Skins
Users can define OpenJUMP skins.
!http://jump-pilot.sourceforge.net/wikiimages/editing%20toolbox/option/2-skin.jpg!
Note that some skins (motif or metal) can look ugly depending the Operative System (Windows Vista or Linux Gnome environment). See "faq":http://openjump.org/wiki/show/FAQ n. 5 for further information about Gnome.
