BreakVal.tml

Breaks a pline in a vertical curve.


Start with:

Profile View: VAL with Vertical Curve


End with:

Profile view: VAL is broken in the Vertical Curve

There are times that you must break a VAL. With the Terramodel commands, you cannot break a VAL within a Vertical Curve. BreakVal will quickly break the profile at any station even in a vertical curve.

How to use the BreakVal command:

After downloading BreakVal.* to the Terramodel installation folder\Terramodel\tmls folder, open a Terramodel project and type breakval at the Terramodel command line:



You will see:

BreakVal command bar

  1. VAL: Select a Vertical Alignment. This must be a pline.
  2. Station: Type the station at which you desire to break the VAL. Click the right mouse button for point snaps.
  3. Labels: If the VAL is labeled, select the layer or layer list to have BreakVal automatically update the references of the label text. If the VAL is breaking into two VALs, then the labels defining the stations for the second VAL will be referenced to the second VAL.
    If the Mode is set to Trim, then the labels will be trimmed as well.

    Update labels to change references.

    Labels dialog box.

  4. Mode Options:
    • Break: This will break the selected VAL creating two VALs. The original VAL will end at the selected station and a new VAL will begin at the selected station.
    • Trim End: This will trim the selected VAL at the selected station. The original VAL will end at the selected station.
    • Trim Begin: This will trim the selected VAL at the selected station. The original VAL will begin at the selected station.
