What is reference elevation?
Reference elevations are elevations that reference an existing elevation or drafting view. They do not create a new view when you add them to your project. You can place a reference elevation in a plan or callout view.
How do you copy an elevation view in Revit?
Copying Plan Views
- Select the view crop boundary of the plan view,
- copy to clipboard.
- Go to the other project.
- Paste – Aligned to Current View or to Selected Level.
What is datum elevation?
A vertical datum is a surface of zero elevation to which heights of various points are referenced. Traditionally, vertical datums have used classical survey methods to measure height differences (i.e. geodetic leveling) to best fit the surface of the earth.
What is MSL datum?
Definition. Mean Sea Level (MSL) is the datum for measurement of elevation and altitude. Mean Sea Level is the equipotential surface of the Earth as described by the WGS84 geoid.
Why can’t I see elevations in Revit?
If the elevations aren’t showing in the browser then they must have been deleted, although Revit warns you before deleting an elevation. If you go to a plan view look at the elevation marker (if you can’t see it then unclick crop view or click on the bulb to reveal hidden elements).
How do you import views into Revit?
Click Insert tab Import panel Insert from File drop-down Insert Views from File. In the Open dialog, select a project file, and click Open. The Insert Views dialog opens, which displays views that are saved in the project. From the list, select an option for views to display.
Are callouts view specific in Revit?
A reference callout is a callout that refers to an existing view. When you add a reference callout, Revit does not create a view in the project. Instead, it creates a pointer to a specified, existing view. You can place reference callouts in plan, elevation, section, callout, and drafting views.
What is vertical datum based on?
The vertical datum is a collection of specific points on the Earth with known heights either above or below mean sea level. Near coastal areas, mean sea level is determined with a tide gauge. In areas far away from the shore, mean sea level is determined by the shape of the geoid.
Where is datum level?
On a construction project, a datum level is an arbitrary horizontal plane of reference from which all vertical dimensions are measured. It can show the vertical height difference between floor levels of a building as well as differences in levels between one part of the site and another.
