Recommended Data Format
The 3DFACE design information is passed directly to the on-board software with minimal processing by the office software. Vertical faces are not allowed in the elevation design. A vertical face is any vertical plane that is defined by a 3DFACE or a closed polyline. If the office software encounters a vertical face, then a message appears. The message states that a design Triangular Irregular Network or TIN cannot be created by using the specified data.Alternative Data Formats
Lines, and open polylines or closed polylines can be used for representing designs. The office software will create a TIN from these entities. A TIN can be created by using various techniques. The TIN that is created by the office software may not exactly represent intended design. For example, polylines that represent contour lines will be triangulated by the office software, but the TIN may not be an exact representation of the design.Caterpillar recommends that the elevation design is represented in the .dxf file by using 3DFACEs.Note: When possible, do not create a TIN from contour lines. Creating a TIN is an inefficient way of creating a TIN. This method will result in excessive data. This data will slow down all further processing.Polylines in a design elevation layer are treated as break lines. These break lines ensure that the generated TIN represents a constant grade between vertices of the polyline. A polyline must not cross another polyline. A polyline may meet another polyline if the polylines meet at a common vertex. Closed polylines that define a design elevation may share a common design boundary. The design boundary must include the same vertices for each closed polyline. If the office software encounters polylines that do not meet these requirements, a warning is displayed. The warning states that a design TIN cannot be created by using the specified data.
Illustration 3 g02268978
Example of an unacceptable common design boundary.
In Illustration 3, the polygons A and B share a common design boundary. The white circles represent shared vertices. The black circle represents a vertex for only polygon B. Because the vertex is represented by the black circle, the common design boundary does not consist exactly of the same vertices for each closed polyline. As a result, the office software would not create a design TIN.Points and vertices of polylines and lines must be separated by at least 1 mm (0.04 inch) horizontally. When points or vertices are too close to each other, all but one of the points or vertices will be ignored when generating the TIN. The office software reports the points and the vertices that have been ignored. Verification of elevation design TINs that are created by the office software can be accomplished by outputting the TIN to a .dxf file. The .dxf file should be Version 10, ASCII that is composed of 3DFACEs.Display
