You can set the detail level for newly created views based on a view scale. View scales are organized under the detail level headings Coarse, Medium, or Fine. When you create a new view in your project and set its view scale, its detail level is automatically set according to the arrangement in the table.
By predefining detail levels, you can affect the display of the same geometry at different view scales.
You can override the detail level at any time by setting the Detail Level parameter in the view properties. See View Properties.
For information on detail levels and the display of structural components, see Detail Levels and Display of Structural Components.
A custom door created in the Family Editor can display differently at coarse, medium, and fine detail levels.
