Profile Curve Between Elements

Used to construct a vertical curve between two designated elements.

You can access this tool from the following:

  • Ribbon: Geometry > Vertical > Curves split button

Use the Profile Curve between Elements tool to construct a vertical curve between two designated elements.

  1. Select the Profile Curve between Elements icon.

    Note: If your View isn't in Profile mode, a message will indicate that you need to Open Profile Model.
    • The Place Profile Curve between Elements 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 requesting that you "Locate First Profile Element", so move the cursor to the element from which you wish to draw a curve then data point (left-click) on it.

  3. Use one of the following methods to set the Back Vertical Offset:

  4. When prompted to Locate Second Profile Element, move the cursor to the element to which the curve must extend then data point.

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

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

  5. When prompted to Locate Second Profile Element, move the cursor to the element to which the curve must extend then data point.

  6. Use one of the following methods to set the Ahead Vertical Offset:

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

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

  7. 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 Length and strike the Enter key then data point.

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

  8. To trim the element at the intersection of the curves or to extend the new curve to intersect with the old, your Offset value must be zero. Strike the down arrow key to choose the Back option then strike the Enter key.

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

Properties

To View the new element's properties, equip the Element Selection tool.

Select the element in the View then let the cursor hover over the selected element. Click the Properties icon to access rule data for the chosen element.

Custom Tool

These pre-customized versions provide a simplified prompt sequence for many common construction tools. Right-click on the Profile Curve between Elements icon then choose Show/Hide Arc from Element Tools to access the following option:

  • Parabola between Elements - Creates a parabola between two elements, Offsets are locked at zero

  • Asymmetric Parabola - Creates an asymmetric parabola between two elements, Offsets are locked at zero

  • Circular Curve between Elements - Creates a simple profile radius between two elements, Offsets are locked at zero

Note: Customized versions are pre-configured to select parabola or curve types negating the need to use ALT key to cycle types.
