Command Description

The Attribute Editor command allows you to edit, add or delete “feature attributes” and “12d attributes” on existing objects in TBC. This a flexible way to change the current attributes on a collection of objects and add “12d attributes” to new objects.

  1. Click in the Entities selection field and then in a graphic view select the objects which you want to edit the attributes of. Click Options for additional selection options.

  2. Attribute type:
    • 12D Attributes – Attributes imported from 12da files. These can be assigned to any of the following objects.
      • Points
      • CAD Points
      • Linestrings
      • Pipes
      • Alignments
      • Polygons
      • Surfaces
      • 3d Shells
      • IFC Meshes
      • Text
    • Feature Attributes – Attributes assigned from an FXL file to an object as part of a feature.
  3. Based on the above selection, the attributes currently on the objects selected will be displayed in the panel. Feature attributes are broken into Name, Count, Code, Type and Value, while 12d attributes are displayed by Name, Count, Type and Value.
    • Editing attributes – Any current attributes in the panel can have their values edited. Once a value is changed the attribute name will colour blue and remain that way until they are applied to the object.
    • Adding attributes – You can add a new attribute to an object by pressing the ‘Add’ button at the bottom of the panel. A box will pop up to select the attribute type and give it a new name. The new attributes in the panel will be coloured green and remain that way until they are applied to the object or the feature definition is edited.
      Note: When adding a “Feature attribute” to a feature, once you press ‘Apply’ the new attributes are also added to the current FXL file in the TBC project. This will not add the “new” attribute to other objects with the same “Feature” in the project unless they were selected at the same time.
    • Deleting attributes – You can delete any current attributes in the list by selecting it and pressing the ‘Delete’ button at the bottom of the panel. Attributes that have been deleted will colour red and remain that way until they are applied to the object.
      Note: When deleting a “Feature attribute” from a feature, once you press ‘Apply’ the deleted attributes will be removed from the current FXL file in TBC and therefore also from any other object using that feature within that TBC project.
    • If attributes with the same name but varying values are selected the rows these occur on will be coloured pale yellow to indicate this.
  4. To edit the attribute definition for feature attributes, select the row in the table, and press the ‘Edit’ button at the bottom of the panel or double click on the attribute name. This will pop out a definition box for the attribute which can be edited. If the attribute is new and has not been applied, then it will automatically be applied at this stage. You can also edit these properties after they are applied within the FXL file under the project explorer. 12d attributes names can be edited in the same way.

  5. Click Apply to apply the changes and keep the Attribute Editor command pane open. The number of attribute edits, deletions and additions will be noted at the bottom of the panel.


Part of the operation of this command allows the user to add and delete “feature attributes” from objects within the TBC project and therefore also the FXL file in the project. The user needs to be aware that the effects are the same as when adding or deleting feature attributes manually from an FXL file.

  • An updated FXL should be exported from the project to be used for future surveys, just the same as if you had updated the FXL manually.
  • If copying the data via a VCL file to another TBC project, then the updated FXL file will also need to be in that project for it to import.
  • If importing and processing JXL or JOB data that was recorded using the “old” FXL, any newly added feature attributes will also be added to this data but have blank values, and any deleted feature attributes will be removed from this data.
  • It is not recommended to reprocess feature codes after modifying the attributes, as you may be left with duplicate points and lines.
