How to create a 3D line feature in ArcGIS?
There are two main ways to create a 3D line feature class: you can either create a brand new line feature class or you can convert existing 2D line data into a new feature class that contains z-values. Check the Coordinates include Z values check box when defining the feature class’s geometry.

Where are the units and datum defined in ArcGIS?
The units and datum for a feature class’s z-values should be defined on the containing feature dataset (if one exists) or on the feature class itself (if there is no feature dataset). If no units are defined, ArcGIS will assume that the Z units match the XY units.
Why are features always modeled as 2D lines?
Any features that live exclusively on the elevation surface, such as streets, trails, and fence lines, should always be modeled as 2D line features. This simplifies the data storage and maintenance of the features, and allows them to automatically adjust their heights if the underlying surface data improves.
Do you need to rebuild terrain in ArcGIS?
Depending on the surface type associated with features added to a terrain, the terrain dataset may need to be rebuilt using Build Terrain. The terrain dataset’s Properties dialog box in ArcCatalog and the terrain layer’s Properties dialog box in ArcMap both provide an indication as to whether the dataset needs to be rebuilt.
How do I add feature class to terrain?
Adds one or more feature classes to a terrain dataset. Input features must reside in the same feature dataset as the terrain dataset. Terrain dataset must already have one or more pyramid levels defined. Depending on the surface type associated with features added to a terrain, the terrain dataset may need to be rebuilt using Build Terrain.
Is there a way to split lines in ArcMap?
Available with 3D Analyst license. You can easily split line features in 3D (ArcScene and ArcGlobe) as well as 2D (ArcMap). Splitting lines results in an existing line feature being broken into several line features. There are several methods to split lines, but not all are shared between 3D and 2D.
What are point, line and polygon features in ArcGIS?
Z-aware point, line and polygon features are simple features that are configured to store z-values when the feature class is initially created in a geodatabase. Point features store one z-value per feature. Line and polygon features store a z-value with each vertex. Multipatch features are 3D shell objects comprising 3D polygon faces.
How are 2D features stored in ArcGIS Pro?
For a basic workflow to get started creating features, see Get started editing. 2D features store x and y coordinates with their geometry. Although 2D features do not inherently store z-values, you can display them in 3D space by deriving z-values from an elevation surface or extruding them to appear three-dimensional.
