You just need to be familiar with your component families and Lead Types.
 
I saw the component had terminals on the Bottom. That means it's a Flat No-Lead QFN, SON, DFN, etc.
 
I'll be relocating this post to the Q&A forum.

Thanks ... so what key features do you look at to make that determination?  I never even considered a DFN as an inductor body style, associating it with ICs and maybe smaller two pin devices like diodes.

This Inductor is a 2-pin DFN (not a Molded Body)

No problem - http://www.coilcraft.com/pdf_viewer/showpdf.cfm?f=pdf_store:xal50xx.pdf

I was using the dimensions from the dash number -331 part.

So, starting with a new inductor and entering the dimensions shown on the first image should have produced a good courtyard.  However, when entering the numbers shown on the Footprint\Dimensions tab with the Use Mfr dimensions checked, you should have been able to see the courtyard restrict while the silk / assembly info remain the same.

Curious.

Can you attach a web-link to the component package datahseet?
 
I looks as though you're using the wrong component family.
 
I cannot reproduce your error in the Molded Body component family.

Using 2012.52 on Win7 x64.
 
I went to create a new inductor from a CoilCraft datasheet.  I entered the dims and clicked OK.
 

 
Then I decided that I needed to use the mfr recommended footprint.  Made the changes per the datasheet, hit OK and noticed that the courtyard moved to reflect the new pad locations but it was now INSIDE the silk/assembly outlines.
 

 
I think this new courtyard would certainly cause issues when placing on a tight circuit board.
 
Thanks,
Billy
