Fence Selection Region

Selects objects within an irregular “fence” shape.

You can use Fence to select either objects that are completely within the selection region (window method), or objects that are either within or touched by the selection shape (crossing method). Toggle between the window and crossing selection methods by using the Window/Crossing toggle on the main toolbar.

Note: If you hold down Ctrl while specifying a region, the affected objects are added to the current selection. Conversely, if you hold down Alt while specifying a region, the affected objects are removed from the current selection.


To select using a fence:

  1. Click (Fence Selection Region).
  2. Drag to draw the first segment of a polygon, then release the mouse button.

    A "rubber-band line" is now attached to the cursor, anchored at the point of release.

  3. Move the mouse and click to define the next segment of the fence. You can make as many steps as you want.
  4. To complete the fence, either click the first point, or double-click.

    A pair of cross hairs appears when you're near enough to click the first point. This creates a closed fence.

    Double-clicking creates an open fence, which can select objects only by the crossing method.

    To cancel the selection, right-click before you release the mouse.
