Projection Type

Sets the projection angle for drawing views.

The projection angle defines where projected views are placed. For example, if the
active projection type is first angle, top views are placed below the front view.
In the third angle, top views are placed above the front view.

Shading/Preview

Shaded view quality

Sets the default resolution for shaded drawing views.

NOTE:

• Resolutions above 150 DPI may not be achievable for large models. The resolution adjusts
  automatically if the specified resolution is not achievable.
• The setting applies only to new drawing views you create. The setting has no impact
  on existing drawing views.

Preview type

Specifies if the temporary graphic shown during view creation is a shaded preview
or a bounding box. Shaded previews take time to generate and may not be desirable
for large models.

Thread Style

Sets the appearance of thread ends in the drawing for section views.

Sets the appearance of thread edges in the drawing for circular view projections of
threads.
