Roads

New features

New stakeout methods for 12da roads

You can now stake out a 12da road using two new methods: One string and Two strings. Use the One string method to stake a string (or polyline) relative to a 12da alignment. Use the Two strings method to stake to a surface defined by two strings (or polylines) relative to a 12da alignment.

For more information, see the Staking out a 12da road section of the Trimble Access Help.

Autodesk Civil 3D LandXML string road file support

Trimble Access Roads now supports the display of Autodesk Civil 3D LandXML string road files in the map.

Use the LandXML export function in Autodesk Civil 3D to export corridor baseline alignments, along with associated feature lines. You will need to extract feature lines from the corridor key point codes before you export the LandXML file from Autodesk Civil 3D.

For more information, see the topic To export LandXML string roads from Autodesk Civil 3D in the Trimble Access Help.

Enhancements

RXL and LandXML stakeout enhancements

The work that was begun in version 2021.20 to consolidate the menu and map-based stakeout workflows is now complete. The workflow for staking a LandXML or RXL road is now the same, regardless of whether you start stakeout from the menu or the map. You can now select To the road, To the string, or Station on the string by interacting with the road on the map, or use the method fields on the form to select these methods or one of the additional stake methods available. The String, Offset, Stations and construction offsets can now be selected directly on the stakeout form, without having to tap additional buttons or use the tap and hold menu.

Construction offset enhancements

You can now key in construction offset values directly on the form. For more advanced features, an Options softkey enables you to access them all from the one screen. You can no longer access the construction offsets from the tap and hold menu.

In addition, you can now apply a station construction offset when staking an RXL road. Previously you could apply a station construction only to LandXML, 12da, or GENIO roads.

When the stake method is To a string with a calculated construction offset applied, a perpendicular cut/fill (Perp. Dist) delta is now reported in addition to the vertical cut/fill delta (V.Dist). This delta is available for RXL and LandXML roads.

Cross slope and subgrade

You can now access the cross slope or subgrade functions using the Cross slope and Subgrade softkeys in the plan view and cross section view. On-screen prompts provide guidance on how to define the cross slope or subgrade.

Skew offset enhancements

When defining a skew offset you can now select the station by tapping on the map. Previously when you did this the method changed to Station on string. To select another station, you can now use the Sta+ and Sta- softkeys when using the Skew offset stake method.

Double-tap to clear map selection

To clear the current selection when staking a road, you must now double-tap an empty space in the map. This is consistent with how clearing the map selection works in General Survey. Previously, the map selection could be cleared in Roads and the method set to To the road with a single tap on empty space.

Improved warning messages for LandXML string roads

The software now warns when an invalid string is encountered when loading a LandXML file. Invalid strings are ignored, and the software continues to load the file. Previously the file would not load.

When selecting a LandXML file to display in the map that has multiple roads with strings that go back on themselves, the warning message now includes the road name, which is useful when the file contains multiple roads.

Tap Skip further warnings to prevent the software showing any further warnings for the road.

Spirals in LandXML string roads

When layering on a LandXML string road in the map, Trimble Access now warns if the spiral geometry is invalid. The horizontal alignment is then adjusted to fit.

For more information, see the topic LandXML string roads in the Trimble Access Help.

Last used stake method

The last used stake method is now remembered when you begin road stakeout.

Switch between plan view and cross section view using a function key

You can now switch between the plan and cross section views when reviewing and staking a road or staking an alignment by pressing the function key you have assigned to this function on the controller keypad. This keypad shortcut replaces the Tab key shortcut in previous versions of the software. Pressing the Tab key now moves between fields in a form.

To assign the function key, tap in the Favorites screen and select the Function keys option. Tap + on the function key you want to use and from the Map controls group, select Toggle Plan / Cross section.

For more information, see the topic Favorite screens and functions in the Trimble Access Help.

Map toolbar enhancements

The Map toolbar in Roads now includes a Video button when connected to an instrument that has video.

When connected to an instrument that has video and running Roads on a TSC5/TDC600 controller, tap the More functions button on the Map toolbar to access the Orbit and Predefined view map tools.

Resolved issues

  • Keyed in roads defined as alignments: We have fixed a workflow issue that resulted in a keyed in road being stored as an alignment.
  • Layer manager does not allow road layer display changes: We have fixed an issue where if you attempted to hide or deselect a LandXML road in the Layer manager, the software erroneously warned that the road was being staked out and you were prevented from changing the display status of the layer.
  • RXL station interval: If you edit the station interval for an RXL road the new value is now remembered when you restart the software.
  • 12da files: Improved support for 12da alignments where, depending on the geometry definition, some alignments could not be set to selectable in the Layer manager.

  • Road surface display: We have fixed an issue where a road did not always display the surface despite having templates assigned.

  • Review using 3D drive: To review a road using 3D drive, the road must now have a vertical alignment.

  • Slow stakeout on Android: We have fixed an issue where the software was slow to respond when staking an RXL or LandXML road on an Android device. This was an issue when the stake method was To the string and you had a calculated construction offset applied. It was particularly noticeable for large road files when using gesture support to zoom or pan.

  • Subgrade offset: If you select a different subgrade position when staking a subgrade position, the offset value at the top of the navigation screen now updates to the new value.

  • Vertical construction offset: We have fixed an issue where the offset was not being applied, resulting in an incorrect V.Dist value when the stake method was Station on string. This was an issue only at the navigation screen when the road consisted of a horizontal and vertical alignment with no templates assigned. The V.Dist value was correct at the Confirm staked deltas and Review job screens.

  • Flickering screen: We have fixed an issue where the Options form would flicker if you opened it from the navigation screen when the stake method was To a string and a Calculated horizontal construction offset was applied.

  • Alignment stakeout: When staking an alignment from the menu, you are now prompted to start a survey if you have not already started a survey.

  • Side slope staking: Using the softkeys or the arrow keys to select a different station at the cross section navigation screen now shows the target in the correct position. Note that this was only a display issue – the navigation deltas were correct.
  • Staking a road with a gap in the template: When staking To the road, you will no longer see the target in the cross section view when your position is over a template element defined as a gap. This is consistent with the software behavior when in the plan view.
  • Stakeout arrow pointing incorrectly: We have fixed an issue when staking a station on a string where the string was a catch point and was some distance away, where the stakeout arrow sometimes pointed in the wrong direction.

  • Cross section view unavailable: We have fixed an issue where occasionally you could not access the cross section view when the stake method was To the string and you were staking to an offset rather than a string.

  • LandXML string roads: We have fixed an issue where strings that went back on themselves were occasionally not being flagged as such.

  • Application errors: We have fixed several issues that caused occasional application errors when using or closing the software. In particular:

    • When selecting a station to stake after having previously staked a station with a keyed in elevation. This was an issue only when the road had no vertical alignment.

    • When selecting an additional string to stake. This was an issue only when the road had no templates assigned.

    • When selecting the To an additional string stake method from the menu when a calculated construction offset had previously been applied.

    • When attempting to view the cross section view when staking To the string with a computed construction offset.

    • When displaying a 12da file in the map where the file contains only the header lines.

    • When changing the Display the road selection screen on escape setting in the Options screen when selecting a road to stake from the menu.

    • When attempting to cancel out of the Exclude strings option when the map is updating.

    • When reviewing a road using 3D drive where some of the vertical alignment is vertical.
