The '''2D Shape Editor''' is a tool in the [[Unreal Editor]] for [[creating 2D shapes]] that can be used instead of [[brush builders]] to construct [[brushes]]. In [[UnrealEd 1]] it still has experimental status and comes without a toolbar. The various features and operations are accessible through the menus, though. The 2D Shape Editor is no longer available in [[Unreal Engine 3]] builds of the Unreal Editor, possibly due to the fact that brushes should no longer be used for complex geometry.

Shapes created with the 2D Shape Editor can be constructed from a combination of linear and bezier segments. The bezier segments will be translated into a number of linear segments, according to the selected detail level for that segment. The final shape can be used as a sheet brush, revolved around an axis or extruded, either parallely, to a point or to a bevel.

==Interface==
[[Image:UnrealEd3-2DShapeEditor.png|thumb|300px|The 2D Shape Editor in [[UnrealEd 3]].]]
The 2D Shape Editor interface is identical in [[UnrealEd 2]] and [[UnrealEd 3]], they only differ in the colors used in their main editing area.
Note that you may have to start UnrealEd 3 with the <code>-nogamma</code> parameter to see the grid lines in the 2D Shape Editor, as unfortunately their color is hard-coded and looks very similar to the background color after the in-game gamma and brightness settings are applied.

===Main area===
Here the shape is displayed on a grid of configurable size. The two thicker grid lines mark the coordinate axes, which meet at the origin. The shape itself is displayed with dark gray lines, its vertices are white squares with black border. Selected vertices are displayed with a thicker red border, the adjacent edge(s) in clockwise direction are also drawn thicker. Bezier segments have two additional handles for adjusting the [[wp:bezier curve|bezier curve]], these handles have a blue border and are connected to their corresponding vertex with a blue line.
The square with the thin red border is the average position of all vertices, the square with the thick green border is the pivot of the shape.

To select a vertex or bezier handle, simply left-click on it. Additional vertices can be selected or deselected by holding Ctrl and left-clicking on them. Similarly the pivot and average position marker can be selected. To move a vertex, bezier handle or the pivot point, drag it with the left mouse button. To move the entire shape, drag the average position marker.

To move the display area in the shape editor window, drag it with the right mouse button.

===Menu commands===
The following list also shows the corresponding toolbar icon for menu items that can be activated via the toolbar.
; File
:; [[Image:2DShapeEditor-Toolbar-New.png]] New: Discards the current shape and starts over with a basic 256x256 square shape.

:; [[Image:2DShapeEditor-Toolbar-Open.png]] Open...: Loads a shape from a 2DS file, discarding the current shape.
:; [[Image:2DShapeEditor-Toolbar-Save.png]] Save: Saves the current shape as a 2DS file. If the shape was never saved, this works like the "Save As..." command.
:; Save As...: Asks for a file name to save the current shape to disk. The default file extension is 2DS.

:; Image
::; Open From Disk...:
::; Get From Current Texture:
::; Delete:

:; ''MRU list'': Displays most recently used 2DS files. Select one of them to open it.

; Edit
:; Insert New Shape: Adds another shape to the current edit area. The new shape is a basic 256x256 square.
:; [[Image:2DShapeEditor-Toolbar-Split.png]] Split Side ''(Ctrl+I)'': Splits the currently selected segment(s) by adding a new vertex in the middle of each segment.
:; [[Image:2DShapeEditor-Toolbar-Delete.png]] Delete ''(Del)'': Deletes all selected vertices. If the average vertex position marker is selected, the entire shape is deleted. This operation has no effect on the pivot or if the shape of a selected vertex has less than four points.

:; [[Image:2DShapeEditor-Toolbar-ScaleUp.png]] Scale Up: Doubles the size of the shape.
:; [[Image:2DShapeEditor-Toolbar-ScaleDown.png]] Scale Down: Halves the size of the shape, aligning vertices to the grid.

:; [[Image:2DShapeEditor-Toolbar-Rotate45.png]] Rotate 45 Degrees: Rotates the shape counter-clockwise by 45 [[wp:degree|degree]] around the pivot.
:; [[Image:2DShapeEditor-Toolbar-Rotate90.png]] Rotate 90 Degrees: Rotates the shape counter-clockwise by 90 [[wp:degree|degree]] around the pivot.

:; [[Image:2DShapeEditor-Toolbar-FlipH.png]] Flip Horizontally: Mirrors the shape at the vertical line crossing the pivot.
:; [[Image:2DShapeEditor-Toolbar-FlipV.png]] Flip Vertically: Mirrors the shape at the horizontal line crossing the pivot.

:; Grid: Changes the grid size. The default grid size is 16.
::; 1, 2, 4, 8, 16, 32, 64
:; Segment: Adjusts the type of the selected segment(s).
::; [[Image:2DShapeEditor-Toolbar-Linear.png]] Linear: Turns them into linear segment(s).
::; [[Image:2DShapeEditor-Toolbar-Bezier.png]] Bezier: Turns them into bezier segment(s).

::; Detail Level: Adjusts the detail level of the selected bezier segment(s), i.e. the number of linear subsegments used to represent it.
:::; 1, 2, 3, 4, 5, 10, 15, 20
:::; Custom...: Allows you to enter a custom number of subsegments for the selected bezier segment(s).

; View
:; [[Image:2DShapeEditor-Toolbar-ZoomIn.png]] Zoom In: Zooms in to twice the current size.
:; [[Image:2DShapeEditor-Toolbar-ZoomOut.png]] Zoom Out: Zooms out to half the current size.

:; Move Camera To Origin: Moves the camera so the two thicker grid lines meet in the middle of the window.

; Process
:; [[Image:2DShapeEditor-Toolbar-Sheet.png]] Sheet: Creates a sheet brush, whose normal vector is one of the three coordinate axes X, Y or Z.
:; [[Image:2DShapeEditor-Toolbar-Revolve.png]] Revolve...: Creates a brush by revolving the shape around one of the coordinate axes. For this operation, all vertices of the shape must be one the same side of the pivot, i.e. all on the left or all on the right side.
:; [[Image:2DShapeEditor-Toolbar-Extrude.png]] Extrude...:
:; [[Image:2DShapeEditor-Toolbar-ExtrudePoint.png]] Extrude to Point...:
:; [[Image:2DShapeEditor-Toolbar-ExtrudeBevel.png]] Extrude to Bevel...:

{{sectstub}}
In UnrealEd 1, the 2D Shape Editor looks much simpler and the menus are structured differently.
