Cropping Imported .pdf ???

[ScaleAero]

I have searched high and low for a crop function and have not found it.

Is this because the trace function renders individual extractions from an imported image
"group"?

Thanks in advance for your assistance as I have .pdf I want to cut. Cropping is the only
thing I have not found...help!

The Crop tool is on the left Tools panel in the Knife menu (6th icon from the bottom).
