Quality in Drawings
Drawing views can be:
High quality.
All model information is loaded into memory.
Draft quality.
Only minimum model information is loaded into memory. Some edges may appear
to be missing, and print quality may be slightly degraded. You can annotate
views in draft quality without resolving the model.
All drawing views are automatically
created in high quality, except if:
You open
a drawing that contains drawing views saved in draft quality in a version
previous to SolidWorks 2006. In this case, the drawing views remain in
draft quality. If you change the drawing views to high quality, you cannot
change them back to draft quality.
You override
the high quality setting for new drawing views (see below).
A drawing can contain views in both modes. The pointer changes to 
when it is over a draft quality drawing view.
To override the high quality
setting for new drawing views:
Click Options
(Standard toolbar) or Tools,
Options.
On the System
Options tab, click Display
Style.
Under Display
quality for new views, select Draft
quality, then click OK.
