Creating composite curves

A composite curve is a continuous boundary, which can be made up of various wireframe objects, as well as the edges of surfaces. In this case it is useful to create a continuous curve from the wireframe lines and arcs that form the outline of the plate, so that it is a single, continuous object.

To create a composite curve from the wireframe objects:

1. Click Wireframe tab > Create panel > Composite Curve.
