3D z-value reference for editing

When you create or modify z-enabled features, z-values are applied in different ways depending on the editing scenario and the tool you are using. Feature construction tools use the default z-values unless you specify a z-value using the elevation tools and settings. Some tools that modify features interpolate z-values and preserve the angular pitch of line segments, while other tools preserve the z-values of the existing features.

Tools that use elevation settings

Editing scenario or toolHow z-values are assigned

Create a new z-enabled feature using tools in the Create Features pane.

Create new feature

By default, z-values are applied to new features in the following ways:

  • In maps, the default z-value is set to zero (0).
  • In scenes, z-values are derived from the active elevation surface when you click the scene.

For detailed steps that show you how to input z-values, see Specify an elevation for 3D features.

Copy Copy

Cut Cut

Paste Special

Copy and paste

Existing z-values are preserved and copied to the new feature. If the copied feature is not z-enabled, then the pasted feature is assigned the default z-value configured for the layer in the map or scene.

The angular pitch of the line segment is preserved and the new vertex is assigned an interpolated z-value.

Split Line Split Line

Split polyline

The angular pitch of the line segment is preserved and the new vertex is assigned an interpolated z-value.

Reshape Reshape

Reshape

The z-values of the existing feature and the new geometry are preserved. New vertices are assigned the z-values of the new geometry.

Split Polygon Split
