Profile Curve Between Points

Constructs a vertical curve between designated points.

You can access this tool from the following:

  • Ribbon: Geometry > Vertical > Curves split button

Use the Profile Curve between Points tool to construct a vertical curve between designated points.

  1. Select the Profile Curve between Points icon.

    Note: If your View isn't in Profile mode, an error message will indicate that you need to Open Profile Model.
    • The Place Profile Curve between Points dialog opens.

    • Checking the box next to any of the fields locks in the associated value.

  2. When you move the cursor into the Profile View, it is equipped with a command prompt that invites you to choose a Placement Method. Navigate the options by striking the up and down arrow keys.

Start\End\VPI

  1. To create a symmetrical, vertical curve defined by a Start Point, an End Point, and the Vertical Point of Intersection, choose Start\End\VPI by striking the down arrow key on the Placement Method prompt. Strike the Enter key to initiate the Start\End\VPI method.

  2. When prompted to "Enter Start Point", so move the cursor to the point at which you wish the curve to originate then data point.

  3. When prompted to "Enter End Point"; use one of the following methods to establish the end of the curve:

    • Move the cursor to the desired location and data point.

    • Strike the left and right arrow keys to choose the Length option on the prompt, key in a value, and then strike the Enter key.

  4. Use one of the following methods to set the VPI (navigate the options by striking the left or right arrow keys):

    • As you move the cursor, a value is displayed on the prompt. Data point at the desired value.

    • Enter a value for Start Grade and strike the Enter key then data point.

    • Enter a value for End Grade and strike the Enter key then data point.

    • Enter a value for Vertical Curve Parameter and strike the Enter key then data point.

Start\End\Pass-thru

  1. To create a symmetrical, vertical curve defined by a Start Point, an End Point, and a point through which the curve must pass, choose Start\End\Pass-thru by striking the down arrow key on the Placement Method prompt. Strike the Enter key to initiate the Start\End\Pass-thru method.

  2. When prompted to "Enter Start Point", so move the cursor to the point at which you wish the curve to originate then data point.

  3. When prompted to "Enter End Point"; use one of the following methods to establish the end of the curve:

    • Move the cursor to the desired location and data point.

    • Strike the left and right arrow keys to choose the Length option on the prompt, key in a value, and strike the Enter key then data point.

  4. Use one of the following methods to designate a point through which the curve must pass (navigate the options by striking the left or right arrow keys):

    • As you move the cursor, a value is displayed on the prompt. Data point at the desired value.

    • Enter a value for Start Grade and strike the Enter key then data point.

    • Enter a value for End Grade and strike the Enter key then data point.

    • Enter a value for Vertical Curve Parameter and strike the Enter key then data point.

High\Low\End

  1. To create a symmetrical, vertical curve defined by a the High or Low Point and an End Point, choose igh\Low\End by striking the down arrow key on the Placement Method prompt. Strike the Enter key to initiate the High\Low\End method.

  2. When prompted to "Enter HighLow Point", so move the cursor to the curve's highest or lowest point then data pointX.

  3. Use one of the following methods to the set the end of the curve (navigate the options by striking the left or right arrow keys):

    • As you move the cursor, a value is displayed on the prompt. Data point at the desired value.

    • Enter a value for Start Grade and strike the Enter key then data point.

    • Enter a value for End Grade and strike the Enter key then data point.

    • Enter a value for Vertical Curve Parameter and strike the Enter key then data point.

Vertical Curve Type

The option for curve type can be changed in the dialog or by pressing Shift key on keyboard. Supported curve types are:

  • Parabola Symmetric Parabolic Curve

  • Asymmetric Asymmetric Parabolic Curve

  • Circular A simple curve defined by radius

Manipulators

Manipulators are available for:

  • Start Point

  • End Point

  • High Point

  • Through Point

  • VPI Point

  • Length
