Final Answer:
To extend two lines to the point at which they meet without adding an additional line segment at an angle while using Chamfer command b) First set the Chamfer Angle to 0.
Step-by-step explanation:
The Chamfer command in design software allows users to bevel the corners between two lines or objects. To extend two lines without adding an additional line segment at an angle, you would first set the Chamfer Angle to 0. This configuration ensures that the lines will meet at their endpoint without creating an additional segment at an angle. By setting the Chamfer Angle to 0, the command will create a straight-line extension between the selected lines, eliminating the creation of any additional line segments or angles.
This method ensures a precise extension of lines without introducing an angle or extra segments, providing a clean and direct connection between the two lines. Setting the Chamfer Angle to 0 essentially instructs the software to extend the lines in a manner that ensures they meet at their endpoint seamlessly without any added angular segments.
Therefore, the correct option is b) First set the Chamfer Angle to 0. Selecting this option within the Chamfer command settings is the most appropriate method to achieve a direct extension of two lines without introducing extra line segments or angles.
