Composite Curve
This functionality is available on Onshape's browser, iOS, and Android platforms.
Represent multiple edges as one Curve. Select multiple adjacent edges, sketch entities and other curves. Selecting non-contiguous edges may result in multiple Curves created. Selections for each Curve must meet at their vertices. (Curves are listed in the Parts > Curves list.)

In the Feature toolbar:

The Composite curve feature allows you to represent multiple edges as one Curve. Select multiple adjacent edges, sketch entities and other curves. Selecting non-contiguous edges may result in multiple Curves created. Selections for each Curve must meet at their vertices. Click the Composite curve feature tool on the toolbar. Select the sketch entities used to make up the composite curve. Curves must not intersect or overlap. In this example, two composite curves are created from sketch entities. Click the green checkmark to accept the new composite curves. The Curves appear in the Curves list.

With two or more contiguous sketch curves in the graphics area:
- Click
.
- Select each sketch curve. (Curves must not intersect or overlap.)
-
Click
to accept.
Selecting non-contiguous edges can result in more than one Curve being created:
You are not able to show/hide the Composite Curve feature; use the show/hide functionality in the Parts (Curves) list instead.

To use a Composite Curve in a feature tool like Loft, select the Curve in the Curves (Parts) list as the profile:
