Quickly creates multiple 3D offsets.

SetOff.tml will:
  • Quickly create up to nine 3D offset lines
  • Allow user to save the group of offsets to be used for different sets (Curb & Gutter, Curb, AC Dike, Sidewalk)
  • Create 3D points for DTMs along straight sections and curves

Start with a 3D set in the plan view,
run SetOff.tml and get something like this:



How to use SetOff.tml

After downloading SetOff.* to the Terramodel installation folder\Terramodel\tmls folder, open a Terramodel project and type setoff at the command line and press the < enter > key.


You will see the following:


  • Select a set or multiple sets for which you desire to create offsets.
  • Select Settings. The 3D offset settings dialog box will appear:


3D Offset Settings

Note: The original set will be replaced by a set with points at the interval selected here. The offsets created will be from this replacement.

  1. Point name: Name given to the points along the original set.
  2. Point interval: Interval between the points created in straight sections. Use the mouse option to pick a distance from the screen.
  3. Maximum middle ordinate: Determines the distance between points created along an arc. Use the mouse option to pick a distance from the screen.
  4. Number of offsets: Number of offsets for the set. When this number is decreased, the last offset is removed.
  5. Offset/Delta Z box: Shows the offset and change in elevation of each offset created. Note: Double-click on the offset value to edit the settings.
  6. Load: Loads previously saved offset/delta z groups or classes.
  7. Save: Saves the current offset/delta z group.
  8. Cancel: Cancels changes.

Add Offsets

  1. Type the number of offsets desired in the Number of offsets field.
  2. From the list of offsets now appearing in the offset/delta z box, double-click on the first.
  3. The Offset properties dialog will appear.
    • Offset: Offset distance from the original set. Positive values are offsets to the right, negative values are offsets to the left.
    • Delta Z: Change in elevation from the points of the original set.
    • Layer: Layer this offset will be created on. Layer 0 will place the offset line on the layer of the original set.
    • Color: Color of this offset line and points. Color 0 will assign the color of the original set to this offset.
    • Point name: Name assigned to the points created on this offset.
    • Click OK when finished with the changes.
  4. Double-click on each offset/delta z and make the necessary changes.

  5. Click Save to save the changes to the offset settings.
  6. Click Load to load a predefined group of offsets.
    • Highlight the desired class and click Load.
    • Click New to create a new class.

  7. Close out of the dialog boxes after changes are made.
  8. Click OK to create the offsets.
  9. Redraw the screen and the offsets will appear.

Programmer's Note:

With one set and SetOff.tml, you could create a proposed roadway in seconds.
