Create Curve at intersection

On the Design tab, in the Editing group, select Curve | Create Curve at Intersection to insert a curve at the junction intersection.

(You can also select a Connect Strings by Curve) option from the same menu.)

Method

Radius

Select this option to insert a curve by defining a radius. Optionally specify the number of points.

Tangent Distance

Select this option to insert a curve which is tangential to the selected point. Specify a distance to determine the length of the curve, and optionally the number of points.

Auto fillet

The Auto fillet option applies whatever fillet radius is needed to determine the arc of the curve.

Number of points

Specifying the number of points on the curved segment is optional. The number of points is calculated automatically when no value is specified.
