Angle bisector between 2D lines

Tool(s): Angle Bisector

You can use the Angle Bisector tool to draw an angle bisector between two 2D lines. The lines can already exist, or you can define them by specifying their start and endpoints. The starting point of the angle bisector is the (virtual) point where the two lines forming the angle meet. The direction of the angle bisector can stretch in all four of the areas formed by the intersecting lines.

Tip: Allplan creates a center line for parallel lines.

To draw an angle bisector

1. Click Angle Bisector (How).
   

   Activate Angle Bisector in one of the following ways

   • Menu bar: Create Draft

   • Palette: Tools Create area in the following module(s):

   Draft

   3D Modeling

2. Click a line or specify the direction by clicking two points.
   

   • Click the point.
   • Align to points using the linear snap function and click the point.
   • Define the point by making entries in the dialog line.

   Tip: To find out how to enter points in Allplan, see Precision Drawing.

   Tip: The shortcut menu and dialog line provide tools and options to assist you in the process of entering points. For more information, see Tools and Options.

3. Enter the second line.
4. Enter the length of the angle bisector in one of the following ways:
   • Enter a value in the dialog line and press ENTER to confirm.
   • Enter a point in one of the four areas.
5. If you defined the length of the angle bisector by entering it in the dialog line:
   Specify the area in which the angle bisector is to be created.
