Existing Surface Layers

The Existing Surface is composed of several layers. The example below shows the available Existing Surface Layers. A brief explanation about the layers is found below.

Data Lines

The Data Lines layer contains the lines, points and labels relevant to the existing ground. Data contained within this layer is used to generate the 3D surface.

Annotation

2D information not used to form the 3D surface. 2D CAD Data is automatically moved to this layer during transfer.

Perimeters

Used to define the bounding edge of the existing ground data.

Stripping Areas

A modifying layer used to indicate areas where vegetation and topsoil is removed prior to starting the design. Stripping Areas modify the Existing and form the Stripped Surface.

Benchmarks

Contains any control points (Benchmarks) specified. These points are often used for re-scaling to plansheet or with AGTEK's Graphic Grade program.

Strata Bore Holes

Points used as boring to describe Strata layers as depths below the existing ground or by elevations that cannot exceed the existing ground.

Strata Break Lines

Break Lines area used to connect the bore holes which help the program determine the strata between the bore holes.

Profile Lines

Used to create profiles and cross sections across the job. This lines are also used to create stations and offsets.

Contours

Lines created when using the Contour Surface command from the Utility Menu in Edit Mode.

Cut/Fill Labels

These are spots entered to be used in conjunction with the User Cut Fill Values located under the View Menu in Planview Mode.

Cut/Fill Lines

Lines that define the boundary of the cut and fill areas on the job. These lines are placed according to the Edit Cut-Fill Transition value.

Haul Path

These lines are generated when calculating Balance Regions. The line runs from the center of mass of cut to the center of mass of fill.

Pipe Lines

These lines are entered to calculate the trench volumes.

Documentation

Contains user added Notes or 3D Notes entered in Sitework 4D or Notes and Photos imported from SmartPlan.

Background Images

Contains the sheet borders for imported PDF and TIF files.
