Go to “Tools” menu and from the drop down menu select “Sketch Tools”. From the side drop down menu select “Sketch Fillet” by clicking on it.

Step 3


Then select the Vertex or corner ‘A’ of the rectangle or select the AB and AD lines. Then an automatic fillet preview is available on the sketch interface.
