Why do some of my extruded objects on my hole punch have blue outlines around them when viewing them? For example, I extruded text 'HOLE PUNCH' and it has a blue outline, even in the DRAWING file as well. How do I remove the outline? It even occurs in some of the rectangular features I've extruded...what does the blue outline around it mean? Clicking and doing everything I know hasn't solved the problem 
Above is an example of when I view the object in 3D space, no matter where I click or what I do the blue outline remains. The HOLE text is a wrapped projection onto a curved surface.
