How to scale drawing without scaling the title block

Hello,

I am new to DraftSight and am learning a few of the ins and outs.  I have figured out how to scale a drawing down in the Sheet tab, since everything is drawn 1:1 in the Model view, but I cannot seem to scale a part up or down without effecting the scale of the title block which I have drawn 1:1 in the Model tab as well.  How do I make my part and title block separate entities so that I can scale the part while leaving the title block alone?  Thanks!
