The Window/Crossing Selection toggle switches between window and crossing modes when you select by region.
- In Crossing mode, you select all objects or sub-objects within the region, plus any objects or sub-objects crossing the boundaries of the region.
- In Window mode, you select only the objects or sub-objects within the selection.
Tip: If you're making sub-object selections of faces and you select more faces than you want, make sure you're in Window mode.
The Selection Region flyout on the toolbar allows you to create different-shaped selection boundaries.
3ds Max automatically saves the Window/Crossing setting in the
3dsmax.ini
file.
Note: You can automatically switch between Window and Crossing Region Selection based on cursor movement direction. To set this up, choose Customize

Select Region Crossing selects objects within the window and also objects it crosses: the trash can, bench, and streetlight.
To select objects within and crossed by a selection region:
- Do one of the following:
- Using the standard menu system, choose Edit
Selection Region
Crossing.
- Click the Window/Crossing selection toggle to display the
Crossing icon.
- On the main toolbar, click the Selection Region flyout and choose a method:
(Rectangular),
(Circular),
(Fence), or
(Lasso). Note: This setting also applies to

(Paint Selection Region), but in this case the boundary is that of the brush, not the region. In other words, when painting a region in Crossing mode, the brush selects every object or sub-object it touches or encompasses.
- Drag to specify the region and select the objects.
