Why do I have to zoom by default in on my image in Mach 3

[edclayton1]

When I bring up Mach 3 with my g code the table display shows my work in the bottom left corner of the display. Even though I configured the drawing and the machine size in Sheetcam to be 48" by 48" in Mach 3 it looks to be a super tiny image in the display area. Why is it so small by default. The objects I drew in using Inscape were about 20" in length so it seems odd that in Mach 3 the image shows up super small by default. Any ideas on why that is would be appreciated.
Thanks,
Ed
