type catalog A list of model elements that belong to a particular family type but that differ in size or other
characteristics. Using type catalogs, you can load only the size you need, rather than loading the entire
family type.
For example, suppose that you want to load detail components for wood framing to use in detail views.
Rather than load the entire Nominal Cut Lumber-Section family, which includes 32 sizes of cut lumber, you
can select the specific sizes that you need.
By using the type catalog to load selected items from a family type, you can reduce project size and limit
the number of items listed in the Type Selector for that family, which, in turn, improves productivity. For
information about creating a type catalog, see
Type catalog for a lumber family
type parameters Settings that control the appearance or behavior of all elements of a particular family type.
Type parameters are also called type properties.
The instance parameters and type parameters of an element combine to establish its element properties.
For more information, see
type properties See
Type Selector A drop-down list on the ribbon from which you can select a family type for the element being
added or modified.
For more information, see
Type Selector when adding a wall
underlay A project view or imported file that you use to help position elements in the current view.
For example, when you use a section view as an underlay to a detail view, model elements in the detail view
display in halftone or a different line weight and line pattern. This allows you to see the difference between
the model geometry (from the section view) and added detail components.
To use a view as the underlay for the current view, set the Underlay parameter in its view properties. See
