  4. Double-click on the component and check on Exclude From Triangulation.

    Exclude from triangulation specifies that features created from points in the component are excluded from triangulation during the 3D Model creation.

Define the beam for the guardrail

  1. Right-click in the Current Template window and select Add New Component > Simple.
  2. Populate the bottom of the dialog with the following data:
    • Name = GuardrailBeam

  4. Double-click on the component and check on Exclude From Triangulation.

    Exclude from triangulation specifies that features created from points in the component are excluded from triangulation during the 3D Model creation.

  5. Save the .itl file.  Click File and Save on the Create Template drop-down.  Saving work frequently is recommended since an autosave feature does not exist.

Insert a point and change constraints (to give the beam a different shape)  

  1. Right-click on the line between points GR_8 and Gr_9 and select Insert Point.
  2. In the Dynamic settings dialog, enter 1.3333, 1.7529 in the xy = field and press Enter on the keyboard (while the blinking cursor is in the xy= field).
  3. Right-click and select Finish.
  4. Right-click on the Gr_4 point and select Add Constraint > Full Constraint.
  5. Left-click on the Gr_5 point and click OK (don’t change the values).
  6. Right-Click on the Gr_8 and Gr_9 points and Delete Both Constraints.
  7. Right-Click on the Gr_8 point and select Add Constraint > Full Constraint.
  8. Select Gr_5 for the Parent Point.
  9. Change the Vertical Offset value to -0.2915 and click OK.
  10. Right-Click on the Gr_9 point and select Add Constraint > Full Constraint.
  11. Select Gr_6 for the Parent Point.
  12. Change the Vertical Offset value to 0.2915 and click OK.

  13. Save the .itl file.  Click File and Save on the Create Template drop-down.  Saving work frequently is recommended since an autosave feature does not exist.

Insert a Null Point

  1. On the Dynamic Settings dialog In the Point Name field type Hinge.
  2. Select xDNC-Do Not Construct for the Point Style.
  3. Right-click in the Current Template window and select Add New Component > Null Point.
  4. In the Dynamic Settings dialog, enter 1.6042, 0.0 in the xy = field and press Enter on the keyboard (while the blinking cursor is in the xy= field).
  5. Right-click the new Hinge point and select Change Template Origin.
  6. Right-click the Gr_ point and select Add Constraint > Full Constraint.
  7. Select the Hinge point to be the Parent Point.
  8. Click OK on the Add Full Constraint dialog.
  9. Right-click Gr_1 point and select Delete Vertical Constraint.
  10. Right-click Gr_1 point and select Add Constraint > Vector Offset.
  11. Select Hinge and Gr_ to be the Parent Points.
  12. Leave the Offset value set to 0.00 and click OK.

    Important Depending on the needs of how the Guardrail should move, or function, other constraints should be changed and tested.

Test the Guardrail

  1. Right-click the Hinge point and select Test Point Controls > Test All.
  2. Move the Guardrail and confirm all points follow the Hinge.
  3. Right-click the Gr_ point and select Test Point Controls > Test Vertical Point Control.
  4. Move the Guardrail up and down.  Notice one point (Gr_3) is not moving as expected.
  5. Right-click the Gr_3 point and select Delete Vertical Constraint.
  6. Right-click the Gr_3 point and select Add Constraint > Vertical.
  7. Select Gr_2 to be the Parent Point.Keep the value at 0.00 and click OK.
  8. Re-test the Gr_ point and confirm it is moving as expected.
  9. Save the .itl file.  Click File and Save on the Create Template drop-down.
