Problem: ArcScene layers display as vertical lines

Description

When adding a 3D feature such as point, line, polygon or TIN to ArcScene, the feature appears as a vertical line.

Cause

The data is in a geographic projection. ArcScene assumes that the data loaded has the same vertical units as the defined horizontal units. This causes the vertical units to be stretched to a great extent.

Solution or Workaround

There are three solutions to this issue; select one of the options below:

  • Project the data to a non-geographic projection.

    -Raster
    1. Start ArcToolbox.
    2. Click Data Management Tools > Projections and Transformations > Raster > Project Raster tool.
    3. Specify the required parameters.
    4. Select a non-geographic projection.
    5. Run the tool.

    -Vector
    1. Start ArcToolbox.
    2. Click Data Management Tools > Projections and Transformations > Feature > Project.
    3. Specify the required parameters.
    4. Select a non-geographic projection.
    5. Specify a transformation if necessary.
    6. Run the tool.


  • Adjust the Z unit conversion for the layer to a very small value.
    1. Right-click on the layer in the table of contents and select properties.
    2. Click on the 'Base Heights' tab.
    3. Adjust the value to a number between between 0.001 and 0.0001 as (see below).

  • Adjust the vertical exaggeration of the entire scene to a very small value.
    1. Click View > Scene Properties.
    2. Click on the General tab.
    3. Adjust the vertical exaggeration to a value between 0.001 and 0.0001 (see below).
