SpaTools: Bisect an angle

 

In the continuation of the last blog about Constructing the triangle when all sides are known, I come to know that we can bisect an angle in CAD with different ways.

 


Prior to discuss about different ways to bisect an angle, let us recall how we used to bisect an angle during high school studies using compass and scale. No doubt, it was so interesting as well as fun to do such exercises.

 


In CAD environment like AutoCAD or BricsCAD, we can bisect an angle in following ways:

  1.   Using XLINE command

 


 

This method creates a XLINE object which is a Construction Line having infinite length with no any defined start point and end point. It is often needed to construct a LINE object which bisects an angle.

 

 

2.     This method is little bit hectic but a line can be created as a bisector of the angle. This involves creation of a circle and trimming of the circle as depicted below:

 


In order to make things simple and automated, I have developed a JIG to bisect an angle and included as the part of SpaTools.

 


At the moment, it accepts two LINE objects as input. It draws a LINE object as output with desired length. 

The updated SpaTools DLL can be downloaded from Cadomation.
