Change the symbology of a TIN

Available with 3D Analyst license.

TINs are a form of vector-based digital geographic data and are constructed by triangulating a set of vertices (points). Features form the edges of triangles and therefore, influence the surface at their location. Since the underlying triangulation defines the surface, you may want to take a closer look at it using TIN symbology renderers in ArcGIS Pro.

You can display just one type of TIN feature, for example, just the triangles or all the TIN features. You can also symbolize each feature type using separate symbology. TIN nodes and triangles can be tagged with integer values to allow you to store additional information about them. These integer values can be used as lookup codes, for example, to indicate the accuracy of the input feature data source or the land-use type code for areas on the surface. The codes can be derived from fields in the input feature classes. You can symbolize tagged features with unique values. There are several different symbology renderers available for TIN surfaces in ArcGIS Pro.

Use the Symbology pane to change symbology of a TIN

  1. Select a TIN layer in the Contents pane.
  2. On the Appearance tab, in the Drawing group, click Symbology.

This opens the Symbology pane. From here, you can modify the desired symbology for the TIN layer selected in the Contents pane. You can also select other TIN layers from the Contents pane and without closing the Symbology pane, you can apply the same symbology to them.

  • Contours



Draw TIN surfaces using one of the following symbology renderers:

  • Simple
  • Elevation
  • Slope
  • Aspect
  • Tag Values

  • Slope values range between 0 and 90 degrees, where 0 indicates no slope. Aspect is also measured in degrees. North is 0 degrees, east is 90 degrees, south is 180 degrees, and west is 270 degrees.
