Command Licensing and Default Menu Location

  • The Surface Area by Slope Range command is part of the RPS Modeling Toolbox
  • The command is located on the Modeling macros menu ribbon
  • The command is located in the Reports menu group


Command Description

Reports the plan and slope areas for cut and fill broken down by specified slope ranges on each of two surfaces. The report uses the isopach computed between the two surfaces (e.g. Existing and Subgrade Adjusted Finished Grade) to determine cut and fill areas and then sums the areas of triangles of both surfaces that fall within the defined slope ranges within the computed cut and fill areas. Ideal for the determination of surface finishing / trim areas in fill scenarios.


Command Interface Description

The Surface Area by Slope Range command dialog looks as follows

Original:
Select the first surface of two required for the command. This will typically be the Existing Ground surface

Design:
Select the second surface of two required for the command. This will typically be the Finished Grade or Subgrade Adjusted Finished Grade surface.

The command utilizes the two surfaces to determine the areas of Cut and Fill between the surfaces. Once the Cut and Fill areas are known, the command then sums the planimetric and surface areas of the triangles for both the selected surfaces and reports those areas based on a series of slope ranges defined in the next section.

Boundary:
If you wish to select a Boundary to limit the reported information, you can select it here. Currently only one boundary is supported.

Cut Slope Ranges:
Create the list of Cut Slope Ranges that you wish to report on. You can enter these in any order, and the command will sort them into a logical sequence from Flat to Vertical. Use the Add, Edit and Delete buttons to the left of the list box to change, add or remove slope ranges. On selecting Add or Edit you will be prompted with this dialog to enter the value at the lower end of a slope range. You can enter slopes as a % i.e. 2% or as a ratio i.e. 2:1 / 1:2

Fill Slope Ranges:
Create the list of Fill Slope Ranges that you wish to report on. You can enter these in any order, and the command will sort them into a logical sequence from Flat to Vertical. Use the Add, Edit and Delete buttons to the left of the list box to change, add or remove slope ranges. On selecting Add or Edit you will be prompted with this dialog to enter the value at the lower end of a slope range. You can enter slopes as a % i.e. 2% or as a ratio i.e. 2:1 / 1:2

OK
Executes the command and generates the Excel style report. Note while the Report is open, the command is locked and no other command in TBC can run. The command will look as follows

The Report is split into 4 parts. Cut Values and Fill Values as well as Surface 1 and Surface 2. Each part reports the Plan Area and Surface Area and breaks out the areas into the defined slope ranges.

Values can be copied and pasted from the report into a full Excel Spreadsheet or can be saved as an .xlsx Excel Spreadsheet as needed. That file can then be opened in Microsoft Excel if required. The file is typically saved in the Project Folder for the current TBC project.

Close
Closes the command without further execution.
