Create Lines

Description

Create line objects by various computational techniques.

Access

Home / Tools / Create / Line

Requirements

Depends upon technique used.

Techniques

Create straight lines using the following techniques.

Create circular arcs using the following techniques.

Create splines using the following techniques.

Create Transition Curves using the following techniques.

Controls

The controls available is dependent upon the technique used.

Control	Description
OK	Compute the vertex location for the current line segment.
End	Ends the current line and stores it in the project.
Close	Create a line segment back to the first vertex in the line. You can continue to add segments to the line.
Back	Remove the last vertex from the current line.
Solve	Click to compute the line from items in the list.
Abort	Cancel the creation of the line.

Click one of the above buttons with a tentative selection in the model view, to accept the selection and perform the action.

Notes

Lines are created on the active layer unless otherwise specified.
The Appearance Attributes of the lines are set by the layer however you can click the Attributes tab to override the appearance.
Click the Attributes tab to view or edit automatically created attributes.
Click the Components tab prior to clicking OK to view the components of a circular arc.
To create single lines for each segment in the current line sequence, select the Automatically Segment Lines checkbox in the Create settings in Options tool window.
When creating circular arcs, the 3D circular arc checkbox determines if values picked from objects in the model are 3 dimensional or 2 dimensional.
Clicking OK for the methods 2 Tangents and Distance, Centre and Radius and Linear Offset ends the line currently in construction and creates a new single segment line or alignment.
