Create From Elements tool
Used to create a terrain model from 3D graphical elements that is ruled.
Found on the Civil ribbon in the Terrain Model group.
Ruled Terrains update dynamically if the source elements are changed. Each element or group of elements of a terrain feature type can be selected individually or via selection set. This tool is useful if the elements do not have consistency symbology or attributes (where the Create From Graphical Filter Group tool may be a better option). After the terrain model is created from the first grouping of elements, the software prompts to append another terrain feature (by defining another selection set of elements) or to create another terrain model. The models are named Terrain Model (Element), Terrain Model (Element) 1, etcetera.
With a selection set of all elements of a type (e.g., all break lines) to be made into a model, select the tool. You are prompted with how many elements in the selection set. Data point to accept. Set the type of elements to be extracted and the edge options.
If no objects are selected when you select the tool, select the elements and then reset to complete the selection set.
|Feature Type||The concept of feature types is used throughout the Terrain Model tools.
|Triangulation Options group||Several of the terrain model tools utilize the triangulation options section where the Edge Method is specified.
Many of the external edge triangles are thin and narrow and not representative of the surface. This is particularly evident where the edge of the data set is concave in nature. One approach to eliminate these triangles is the use of the Edge Method.
