Diagram images rather small when published in Word doc

[steely1]

I have a SysML model which I'd like to publish as a report.  I use Report Builder > Simple Diagram Report which gives me all the diagrams within a Word .doc file.  The trouble is, the diagrams in the Word doc are quite small which makes the text unreadable. 

How do I tell EA to increase the size of the diagram images in the published doc, for instance scaling so they fit the width of the page in the Word file?  (instead of covering half the page width.)

I've tried various things in the Diagram properties (Advanced > scaled printing, and Page Setup) but they've had no effect on the image size.  Save > Scaling has no effect either.

I can stretch the images, within Word itself, so they better fit the available page.  But this is a real faff as there are many images.

In your diagram properties, make sure the Hide Page Border is not set. Than you are able to see the page boundaries. Adjust your diagram so that it fits the page.
