Vectorworks Tip #151 – Basic Tools – Fillet Tool
The fillet tool is used to join two linear objects. It has three ways of joining the linear objects together: placing the fillet without affecting the other objects, placing the fillet and splitting the other objects and placing the fillet and trimming the other objects.
Click on the first linear object then move your cursor and click on the second linear object. Vectorworks will then place the fillet between the two objects.
This also works with walls.
