The Vector Crop Tool allows you to remove portions of a selected object (or grouped objects) non-destructively and to specific aspect ratios. Images can also be cropped.
To apply a crop:
With the Vector Crop Tool selected, do any of the following:
Drag a corner handle to apply an unconstrained crop from the selected corner. Cropping an image from a corner will maintain the image's aspect ratio.
Drag from an edge handle to apply a vertical or horizontal crop from the chosen edge.
To reposition objects within a crop area:
With the Vector Crop Tool selected, drag within the crop area.
