Long Section by Freehand

(This functionality is available with the Profiles and Design module)

Creates a new long section between two points.

The points can either be real points in the data base or any freehand position the user wishes to select. A straight line will be assumed between the two points.

A pair of Point Identifiers separated by .. through the keyboard, or if this field is active, snap to any points in the plan view.

Note: If you use the accept (left) mouse button without snapping first, the mouse position will be taken from the screen and shown as a freehand position.

To obtain this option, select the Profile/Long Section command and the Method/by Two Points command from the Profiles task to display the relevant dialog box.

The long section to be created uses the parameters set in the Long Section Parameters Dialog Box.

Long Section by Two Points dialog box

Item	Used to
Long Section name:	Enter a new long section name into the list, or select an existing long section from the list. If the long section name has already been used, you will be given the option to overwrite it with the new long section when the OK button is selected. This can be a unique name up to 31 characters.
Point Range	Enter a pair of point identifiers separated by .. through the keyboard, or if this field is active, snap to any two points in the plan view.
Open Long Section in:	Select if the long section is to be displayed when created. The user has three options, they are. Do not open - If this option is selected the long section will be generated and a long section view will not be created. New Long Section View - If this option is selected a new long section view will be created and become the current view when the long section is generated. Long Section View X - All existing long section views are available for selection from the list. They are named Long Section 1, Long Section 2, etc. If there is only one existing long section view, then its name is "Long Section View". If you enter a long section name that already exists and then create a long section, you will be asked to "Append", "Overwrite" or "Cancel". If you choose to append or overwrite and the relevant long section is currently being displayed in one or more long section windows, then all instances of it will be replaced by the new version of the long section.
Parameters:	Open the Long Section Parameters Dialog Box.
Create:	Generate the long section and close the dialog. Notes: The long section created will only be defined within the area where elevations can be extracted. For instance, if the line defined by the freehand points starts beyond the area of a model from which the elevations are being extracted, the long section will only commence at the edge of the model. If the long section name used already exists a dialog box will appear asking whether to Append, Overwrite or Cancel.
Close:	Close the dialog without generating a long section.
Help:	Display the help for this function.
