The Create Round Corner function creates a new arc at the intersection of two lines and rounds out the corner area. To do this, use the Create round corner function in the Tools menu. You do not have to select the lines beforehand.
Parameters
Specify the fillet radius r of the arc to be created between the lines.
Options
If the "Cut lines" check box is selected, the projecting lengths of the original lines are deleted within the corner area after the fillet has been created.
The "Delete corner" option also removes the point at the original intersection.
Select the "Divide arc into segments" check box to divide the arc into a corresponding number (n) of straight segments.
List of Lines
You can select the lines in the work window with a mouse click or enter the line numbers directly in the text boxes. When entering the line numbers directly, you can swap the first line number with the second one using the button and delete the line numbers using the button.
