Properties

Use this tab to define how the program calculates and documents quantities.

Where can I find the dialog?

In the toolbox, select the SFI Properties... icon.

Calculation Method

You can choose from the following calculation methods:

  1. Parametric method
  2. Manual method
  3. 3D lines
  4. Manual/3D lines

Theoretical and Physical Layers in the Calculation

When building Gemini theoretical layers and calculating quantities, you must select which layers to include in the calculation. The following options are available:

  1. Only VIPS layer types
  2. Only Gemini layer types
  3. Gemini theoretical layers against VIPS physical layers

Calculation Standard

You can choose from the following calculation standards:

  1. None
  2. Process code
  3. NS3420

Under the Quantity Types tab, you can retrieve suggestions for quantity types. The available quantity types depend on the selected calculation standard.

Note

If you change the calculation standard, the program does not automatically replace old quantity types. You must do this manually in the quantity types tab.

Type

You can choose from the following types:

  • Unspecified
  • Road
  • Railway
  • Trench

Type is used in several places in the SFI model.

The first time you close the properties dialog after creating a new SFI model, the type also determines which editing dialog starts:

  • Line Definition starts for type Road
  • Line Definition Data starts for type Trench

Type is also used when building special grading for railways. For railways, special grading is adjusted relative to the lowest rail (VIPS layer type, since these are not built).

Type is also used in the Swedish market to determine how pile numbers are specified in plan and profile drawings. In the Norwegian version of the program, pile numbering is the same in all cases.

When importing VIPS projects, the type for road and railway is set automatically.

Road Class

This option is relevant when using the SFI model for road design.

Road classes are divided into standard road classes and user-defined classes. The following categories exist:

  1. HB N100 2014
  2. Agricultural Roads 2013
  3. User-defined

For each category, you can choose from defined road classes. Use the Show button to view the associated parameters.

If you do not want a connection to the road standard, select Blank in the class field.

With the ... option, you can view existing road classes or create new user-defined classes.

You can update parameter values in the SFI model using the Update button. The Update button becomes active if parameter values in the SFI model differ from those in the associated road class (standard or user-defined).

Automatic Mode

For the parametric method, this will always be the case, so the option is grayed out for this calculation method.

The option is active for all other methods but is not allowed if any profiles are locked or contain quantities reported to Gemini Connected.

Warning

You will receive a warning if the file contains VIPS data, as these will be deleted if you check automatic generation and building.

Work Area

With this option, you can set a work area for cross-section editing. Only the profiles within this work area will be shown in the list. Three dots at the beginning and end of the list indicate that a work area is defined and that the SFI model contains more profiles.

Example of a work area

The option is only active for the manual calculation method. In such projects, it is common to work with a subset of profiles at a time (road projects with gradual progress). It can be useful to set a work area to avoid unnecessary scrolling in a long list of cross-sections.

Save Template... and Use Template...

You can save all parts of the setup, for parametric and manual methods, to a template using the Save Template... button.

You can later retrieve this setup when creating an SFI model or in an existing SFI model using the Use Template... button.

Warning

For road parameters, superstructure parameters, and tunnel parameters, the program deletes existing content first. For example, if you choose to retrieve superstructure parameters from a template, you will lose the existing superstructure setup.

Layer names, metadata, quantity types, and labels are handled slightly differently than parameters. When you retrieve these from a template, you are asked if you want to keep the existing setup in the SFI model. If you answer Yes, the existing content is merged with the new content.

Update External Lines

An SFI model can have several lines in addition to the centerline. You can edit these using the Extra Lines... option in the Planning, Design, and Execution toolset. Extra lines can belong to the active SFI model or be imported from other SFI models. In the latter case, information about the external model and external line will be present in the active SFI model. This will also be reflected in the line name, for example, 2.01_Road2.sfi.

If line 2.01 in the SFI model Road2.sfi has later been changed, you can use this option to update the external line in the active SFI model.

Save Data

You are working with a data structure in memory (not directly with the storage format). Only when you use the general save options in the File menu, the toolbar, or the Save Changes... button in this dialog, is the content written to the file.

If you want to undo changes made, you can click Discard Changes.... The content from the previous save will then be restored.

With the Save Copy As... option, you can create a copy of the SFI file.
