Rounding an Intersection On the Edit menu, click Trim, Round to create an arc with a predefined radius to connect two existing entities smoothly. Lines, arcs, circles, and polylines can be rounded with this command. AutoSketch trims off or extends the two entities to meet the endpoints of the new arc. s When rounding a middle section of a polyline to another entity, the polyline breaks into two polylines at that segment. s When rounding two adjacent segments of the same polyline, the arc becomes a bulge segment of the polyline. Non-adjacent segments of the same polyline are not allowed to round. s When rounding two end segments of a polyline, the polyline becomes a closed polygon. s When a circle is rounded to another entity, it breaks into an arc at the point where it intersects with the new arc. A rounded corner may create three separate entities which are not joined together. For information on joining entities, refer to page 294.
