In the overall urban planning, whether to use chamfer or fillet for road red line, how to use fillet and chamfer, and how to distinguish them? Ask for an answer, thank you.

Chamfering can be used to intersect two straight lines without leaving threaded ends, while fillet can create an arc between the two straight lines, and the radius of the arc can be set by yourself. To use fillet, first click the fillet button, then enter r, then enter radius, and then pick two straight lines to fillet.

Please pay attention to the following command line when using.
