Pattern scale too big

Hello! 

I am trying to import a dxf pattern file. When I import the file, the scale is too big and I cannot see all the pieces. I have checked my unit settings and the size multiplier is only set to x1. The scale is in mm, and I see the size of the workspace is up to 7500 mm but I cannot zoom out any further to see the complete pattern set.

I am not sure how to scale them down - I've checked for any similar questions but can't find the same issue. Please see a screen shot below of what I get when I import the pattern:
