TIN Files
Triangular Irregular Network (TIN) files describe a design surface with a mesh of triangles.A TIN is a better format than a grid for modeling design surfaces. A TIN more accurately represents sharp edges and uses fewer points in order to model the same design. In order to transfer a TIN into the AccuGrade System, create the TIN as a .ttm file.The AccuGrade System can use these formats directly. Alternatively, use the SiteVision Office software to convert the TIN or ttm files to a svd file format.Grid Files
A grid file is a rectangular grid of points normally derived from other digital elevation information or field survey data. An elevation is assigned to each point in the grid.In order to transfer grid DTM data into the AccuGrade System, create the grid in .dtx file format. The AccuGrade System can read this format directly.Alternatively, use the SiteVision Office software to convert the DTM or dtx files to a .svd file format.Sloping Surfaces Files
Sloping surfaces are defined by a master alignment and a slope on either side. Working with sloping surfaces is similar to working with a dual slope level laser. The difference is that with a sloping surface design, two different planes are defined at the same time.You can enter sloping surface designs in the office. The operator can also enter new sloping designs and edit existing sloping designs in the field using the Display. Refer to Operation and Maintenance Manual, "Sloping Surface Design" for more information.A sloping surface can be defined in two ways.
Point / Direction method - one set of coordinates, direction, grade, and left/right cross slope
2 Point method - two sets of coordinates and left/right cross slopeUse the method that is most convenient. Both operate in the same way for guidance.In order to create a new sloping surface design in the office, use the SiteVision Office software.With the sloping surface designs created in the office, you can also define a polygon in order to indicate the extents of the surface design.Level Surfaces Files
A level surface design contains a name and an elevation.You can enter level surface designs in the office. The operator can also enter new level designs, and edit existing designs in the field using the Display. Refer to Operation and Maintenance Manual, "Level Surface Design" for more information.In order to create a new level surface design in the office, use the SiteVision Office software. With level designs that are created in the office you can also define a polygon in order to indicate the extents of the surface design.Reference Surface File
Another type of file in the design folder can be the Reference Surface file. A reference surface modifies one of the previous design types. This file is used in order to give vertical guidance at predetermined distances that are above or below the design surface.A number of reference surfaces can be held in the same Reference Surface file.In order to create a Reference Surface file in the office, use the SiteVision Office software.Note: An .ofs
