Inserting Line Segments

You can insert line segments of various kinds for existing line, arc, or spline objects.

1. Select a line segment in the History Tree (not the modeler window). The individual segments entries are CreateLine, CreateArc, CreateAngularArc, or CreateSpline.

   This action highlights the object and enables the Insert Line Segment subcommands in the Draw menu.

2. Using the menu bar, go to the Draw > Line Segment submenu and then choose either the Insert Segment Before or Insert Segment After submenu.

   Alternatively, right-click a polyline segment in the History Tree and, from the shortcut menu, choose either the Insert Segment Before or Insert Segment After submenu

3. Use this submenu to specify the kind of segment to add. The inserted segment can be: Straight, Spline. 3 Point Arc, or Center Point Arc.
4. Depending on your selection in the previous step, do one of the following:
   • If you clicked Straight, follow the procedure for drawing a straight line.
   • If you clicked 3 Point Arc, follow the procedure for drawing a three-point arc line.
   • If you clicked Center Point Arc, follow the procedure for drawing a center-point arc line.
   • If you clicked Spline, follow the procedure for drawing a spline.
   Note:

   When inserting straight segments or arcs, the insertion operation will terminate as soon as you complete the definition of a single new segment. For splines, you can insert a spline with any number of defining points, and the insertion operation terminates as soon as you terminate the spline.

5. Repeat steps 1 through 4 for each segment of the polyline before or after which you want to insert a new segment. The endpoint of the previous segment serves as the start point for the next segment.
