The SOLIDWORKS Composer Digger tool lets you zoom parts of your model to show a detail view of complex geometry, you can change opacity, visibility, and capture a 2D image.

Follow the steps below to use the SOLIDWORKS Composer Digger in animations and apply a fade in and fade out effect without using the actual fade in and fade out tools on the timeline.


  • Place the timeline bar at 2.5 seconds where-ever you want the digger size to be maximum.Now toggle on digger using space-bar or Home > Digger tool.
  • In the view-port drag the center of interest on the geometry actor you would like to zoom in onto.
  • Resize the digger using the radius handle and click on set digger key on timeline toolbar, to capture the digger key in key track.


  • Copy the step 1 digger key by holding Ctrl and dragging and dropping it at 2 seconds.
  • Using the radius handle reduce the digger circle size.
  • Capture new digger size by settings the digger key again.

I copied the digger from step 1 to step 2 position to maintain the location of digger in viewport.


  • Now copy the digger key in timeline from 2.5 sec  to 3.5 sec holding Ctrl + drag and drop.
  • This will allow us to maintain the same digger size between 2.5- 3.5 seconds.


  • Copy the digger key from 2 seconds to 4 seconds, this will allow us to maintain the same position and (small) size of the digger circle.


  • Place the timeline bar at 4.5 seconds
  • Toggle the digger off using space- bar or Home > digger tool and now capture the digger key again to make sure digger remains off through out the animation.

Hence, just resizing the digger helps us to create the fade-in and fade-out effect while using digger tool in animation.
