Fillet

The Fillet button connects two separate line segments with an arc.

If the segments intersect - superfluous parts are automatically cut off after the use of this tool. If the line segments do not intersect, the segments can be extended. The Fillet button can be found in the Editor tab under the Instruments section.

Select the first segment and press the Fillet button (Editor Tab -> Instruments -> Fillet). Select the second segment.

Example 1: intersecting lines

Example 2: non intersecting lines

Note: arc's radius is available for changing:

•	press the Fillet button;

•	place the mouse cursor over the drawing field; the field in the dynamic input shows the radius of the fillet arc (physically this is  the distance from the intersection point to the sections' cut off points);
