How to bisect an angle in ZWCAD?

A client asked me how to bisect an angle in ZWCAD recently. And I draw a conclusion that there are three methods:

1, Use Construction Line command
On Draw toolbar, click the Construction Line button and enter B to select the Bisect option. Then follow the prompt to select the vertex and two sides of the angle. Now you can get the bisector.

2, Use Dimension command
Firstly is to make an angular dimension for the angle. Then click the Line button on Draw toolbar and select the vertex point as first point of the line. Another point of the line is located at the midpoint of the dimension arc. Now the bisector is available and the angular dimension could be deleted.

3, Use Arc command
Firstly draw an accessorial arc using the angular vertex as center with start from one sides of the angle to the other side. Then draw a line with the angular vertex as starting point, and the midpoint of the arc as end point. Now the bisector comes out.Similar with the method 2.
If you have some experience on using CAD software, please share with us.
4. Use the attached lisp program to create bisector.Illustration video is available in the compressed .rar folder.
One more tips, we can user this lisp program to get it run.
