I use Microsoft Word to write a tehcnical document. When I embed illustrations in the document, I use a canvas [my own translation from Swedish ('arbetsyta')] and draw inside it. This way I can manage the whole illustration as one single 'package'. However, I experience one problem with this approach (besides a large number of bugs in Word). I use a circle sector to draw angles between two lines, as illustrated below (the angle φ).
But now I cannot crop the canvas as to remove the large whitespace in the upper part of it, because the circle sector occupies this area:
What is the most convenient workaround?
