File Menu


5/34

The File Menu

The File commands move various types of data in and out of memory. These data types include digital

terrain models, coordinate geometry, template libraries, roadway design, and preference information. You

can also import and export data in various industry standard formats.

New – creates new files.

Open – opens existing files.

Save – saves existing files.

Save As – saves existing files to another name or to another directory.

Close – closes existing files. Project Defaults – sets the default directory locations for opening/saving files.

Project Options – defines controls that affect the system-wide operation.

Text Import Wizard – imports alignments, event points, cogo points, and surface data in a

variety of ASCII formats.

Import – imports existing data.

Export – exports survey data and MicroDrainage types of files.

Translators – translates data to a variety of industry standard formats for import and export.

Exit – exits the product.

• Use this command to set the default

directory locations for opening/saving files.

• You can also set up preference files to be

opened when BRT is started – AMEY BRTis set as default here.

• You can specify a path for each file type

as well as the name of each preference

file to be opened.

• You can set up multiple configurations and

save them under different names –

separate ones for each project.

• You can also retrieve a set by selecting a

name from the drop down box.

Set Project Defaults Dialog

• The Options dialog box controls parameters that

affect system-wide operation – we just need to

ensure the Amey BRT preference is loaded here

(if Projects Defaults are set correctly this will

happen automatically when you open BRT)

• The Rail Tab - Use this tab to set default cant

values used by the Cant Editor and Maglev

Superelevation Editor commands.

the Active Project Settings dialog box

A change to any of the active settings is effective

immediately, and other commands automatically

become aware of the change.

Active Project Settings and Global Scale Factors

The Global Scale Factors dialog box gives you

access to scale factors for text, cells, and line

styles.

Use these to change your required plot scalebefore displaying graphics from BRT (0.2=1:200;

15/34

Locks Menu


16/34

The Locks Menu - 1 of 3• Feature Filter

• The Feature Filter lock is a global setting that enables or disables The Feature Selection Filter

and The Survey Style Filter.

• Will be covered at a later date with surfaces.

• Feature Highlight

• Use this command to highlight selected features in plan view.

• Will be covered at a later date with surfaces.

• Style

• The Style locks affects two groups of commands: the View Surface commands and the

Annotate Cross Section command.

• Will be covered at a later date with surfaces and cross-sections.

• Pencil/Pen Mode

• The Pencil/Pen lock applies to plan display only and controls what happens when a piece of

graphics is redisplayed.

• Pencil mode – graphics persist only until the item is redisplayed; no duplicates

• Pen mode – graphics are permanent; allows duplicates (see the Delete Ink lock)• Graphics written in Pen mode using vertical commands are not retained between edits of

display.

• It is critical to understand that the current setting of the Pencil/Pen lock is irrelevant in

determining what will happen when you redisplay a piece of graphics. What is relevant is

whether the existing graphics were displayed in Pencil mode or in Pen mode.


17/34

The Locks Menu - 2 of 3• Delete Ink

• The Delete Ink lock allows your redisplayed graphics to replace even graphics that were drawn

in ink.

• Locate Lock

• The lock applies when you use a locate button (indicated by a crosshairs icon) to specify a

position in the graphics file.• If the lock is set to graphics (the icon shows a single, red line), locate actions will seek the

nearest displayed graphics.

• If the lock is set to features (the icon shows an image of a surface), locate actions will seek the

position of the nearest feature in the active surface whether or not the feature is actually

displayed.

• Snap

• The Snap lock on the toolbar can be set to either Point Snap mode, Element Snap mode, or No

Snap mode. Click the toolbar button to cycle through the three settings.

• The Point Snap lock enables or disables your ability to snap or lock onto any point contained in

the geometry project.

• Use this lock to aid the placement process of geometry elements.• The Element Snap lock enables or disables your ability to snap or lock onto any geometry

element in the geometry project.

• With this lock toggled on, the software snaps to the element nearest the data point you place in

the drawing file.

• When using a point pick button element snap will snap to a point in the same manner as Point

Snap.


18/34

The Locks Menu - 3 of 3• Station

• The Station lock is applicable only when the first station specified on the horizontal alignment is

an odd-numbered station (for example, 238) and you are generating cross sections, executing

the Roadway Designer, or generating station type reports.

• Station lock on and the first station is 238 and the station interval is defined as 50, the software

performs the command action at stations 238, 250, 300, and so on.• Station lock off and the first station is odd-numbered, the software performs the command

action at odd-numbered stations only (for example, 238, 288, 338).

• Report

• The Report lock is used by several commands to control whether or not the command displays

output in a dialog box as the command calculations are performed.

• If this lock is off, the command processes and stores results without displaying them in an

output dialog box.

• Cogo Audit Trail

• This document defines the coordinate geometry audit trail.

• The intent of the audit trail is to record all coordinate geometry results to a text file.

• Toolbar

• This command toggles the display of the Locks toolbar.
