Resizing Areas in a Blender Window
Regardless of the type of editor that’s contained in an area, you modify and change all areas in a Blender window the same way. To change the size of an area, left-click the border between two areas and drag it to a new position. This method increases the size of one area while reducing the size of those that adjoin it.
If you have only one area in your Blender window, it’s exactly the same size as that window. To resize it, you need to either adjust the size of its parent Blender window or split a new area into that space, as covered in the next section.
Splitting and removing areas
While working in Blender, it’s pretty common that the default layout isn’t quite what you need to work efficiently. Sometimes you may need an additional 3D View or you may want to see the UV/Image Editor in addition to the 3D View.
To create either of these layout changes, you need to split an existing area into two. You can split or join areas by right-clicking the border between two areas and choosing either Split Area or Join Area from the menu that pops up.
However, there’s a faster way. Look at the corners in the bottom left and top right of any area. These corner widgets are marked as a triangular region indicated by diagonal lines. To split any area into two, use the following steps:
Left-click one of the corner widgets and drag your mouse cursor away from the area’s border.
Drag your mouse cursor left or right to split the area vertically.
Dragging it up or down splits the area horizontally.
As you drag your mouse, the areas update in real time so that you can see the result of the split while you’re working.
If you decide that you actually don’t want to split the area, you can cancel the operation by right-clicking or pressing Esc.
If you want to remove an area, the process is similar. Rather than splitting an area in two, you’re joining two areas together. So instead of left-clicking the corner widget and dragging your mouse cursor away from the area border, drag it towards the border of the area you want to join with. This action darkens the area your mouse is in and draws an arrow to indicate which area you want to remove.
This figure shows the process of splitting an area and then removing that area.
Duplicating an area to a new window
In addition to the new way of splitting and joining areas, you can use these corner widgets to duplicate any area into a new Blender window of its own. You can move that window to a separate monitor (if you have one), or it can overlap your original Blender window. And within this new Blender window, you can split the duplicated area into additional ones as you like.
This area duplication feature is a slight violation of Blender’s non-overlapping principles, but the benefits it provides for users with multiple computer screens make it very worthwhile.
To take advantage of this feature, follow these steps:
Shift+left-click one of the corner widgets in an area and drag your mouse cursor away from it in any direction.
This step duplicates the area you clicked in and creates a new Blender window to contain it.
You can also achieve this effect from the header menu of some editors by choosing View ➪ Duplicate Area into New Window.
Close the additional Blender window by clicking the close button that your operating system adds to the border of the window.
