Angle bisector between 2D lines

Tool(s): Angle Bisector

You can use the Angle Bisector tools to draw an angle bisector between two 2D lines. The lines can already exist, or you can define them by specifying their start and end points. 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: In the case of parallel lines, the program creates a center line.

To draw an angle bisector between 2D lines

1. Click Angle Bisector (How).
   

   Activate Angle Bisector in one of the following ways

   • Actionbar:Role Draft Task Design Task area 2D Objects

   • Menu bar: Create Draft

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

   Draft

   3D Modeling

2. You can apply symbols to the start point and end point of the angle bisector or draw the angle bisector as a pattern line.
   

   You can apply start symbols and end symbols to various 2D elements. To do this, you can use the Properties palette - Element area.

   • Select the symbol you want to use and define its size in millimeters.
   • Decide whether you want to apply a start symbol or an end symbol or both symbols by selecting the relevant the check boxes.
   • While drawing, you can change the symbol or switch it off at any time.
3. 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.

4. Specify the second line.
5. 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.
   • Click a point in one of the four areas.
6. If you entered the length of the angle bisector in the dialog line:
   Specify the area in which you want to create the angle bisector.
