Selecting an occluded textured geometric element through alpha channels

If you have a dense scene with many geometric elements and you need to select a partially occluded geometric element in the background, you can select an element in the background through the alpha channels of partially transparent textured geometric elements in the foreground using the Easy Selection button () in the Viewer toolbar or its keyboard shortcut Alt + Shift + A, and a combination of other keyboard shortcuts to speed up the selection process.

The following image shows partially transparent textured elements, all with an alpha channel. The alpha channels are the sun-shape center of the geometric elements.

To select an occluded textured geometric element in the Viewer window through an alpha channel:

1. In the Viewer toolbar, click the Easy Selection button () or use the keyboard shortcut Alt + Shift + A to toggle the Easy Selection button on ().
2. In the Viewer window, click through the alpha channel of the textured geometric element in the foreground that occludes the geometric element behind it.
   

   The geometric element behind the geometric element in the foreground is shown selected as its border is highlighted.

   

To select an occluded textured geometric element in the Viewer window through multiple alpha channels:

1. In the Viewer toolbar, click the Easy Selection button () or use the keyboard shortcut Alt + Shift + A to toggle the Easy Selection button on ().
2. In the Viewer window, click through the alpha channels of the geometric elements in the foreground that occlude the geometric element in the background.
   

   The geometric element in the background is shown selected as its border is highlighted.
