Profile Curve Between Elements
Used to construct a vertical curve between two designated elements.
You can access this tool from the following:
Use the Profile Curve between Elements tool to construct a vertical curve between two designated elements.
-
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. -
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.
-
Use one of the following methods to set the Back Vertical Offset:
-
When prompted to Locate Second Profile Element, move the cursor to the element to which the curve must extend then data point.
-
When prompted to Locate Second Profile Element, move the cursor to the element to which the curve must extend then data point.
-
Use one of the following methods to set the Ahead Vertical Offset:
-
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):
-
