Having used Revit for several years now, I sometimes forget that the language used within Revit is quite obscure and a bit geeky. For those new to Revit I have created a quick blog explaining 11 key terms.
An annotation crop region fully crops annotation elements when it touches any portion of the annotation element, so that no partial annotations are drawn. The annotation crop can be turned on in the view properties under the Extends section
The crop region controls what is visible in the view
This controls how elements that are farther away from the viewer display in section and elevation views. My Colleague Simon Locke has created a more in-depth blog on Depth Cueing
Entourage includes the landscaping and other environmental features shown in a rendering of a building. For example, entourage can include plants, trees, people, cars, signs, and office components. Like model elements in Revit, entourage objects are defined in Revit families and are in the C:\ProgramData\Autodesk\RVT 2018\Libraries\UK\Entourage folder
An Underlay is used to show another level information in halftone on a plan view. To Activate it, go to the view properties and select the required view.
Parameters are information stored in each element in the project. It can be text information, dimensions or any option specific to elements. In the image below, you can see parameters for a structural column properties dialog box.
If you are familiar with AutoCAD, then this is the equivalent to the Hatch command. It is a 2D pattern constrained by boundaries.
Visibility Graphics (Shortcut: VG) menu is used to control the visibility of all elements in the current view. Simply uncheck a category to hide it completely from the view or override the current settings to your project specific requirements.
Pin (Shortcut: PN) is used to make sure elements can't be modified or moved without unpinning first.
Use the split face (Shortcut: SF) command to apply multiple materials on a surface.
In a plan view or reflected ceiling view, this controls where the view is cut and the depth of the viability. My colleague Pat Mullins has a great blog for an in-depth view on the View Range controls.
