Tutorial: Modifying a surface body

This tutorial shows you how to create complex surfaces, starting from sketch lines and curves, using spline sketches to turn straight edges into curved ones. You take advantage of the Timeline to make changes, by rolling back to make changes to the underlying surfaces, without redoing all the subsequent tools.

In this tutorial, you

• Setup the project with appropriate units

• Create complex surfaces from simple sketch lines and curves, and modify their size and shape using the Trim and Extend tools.

• Roll back the Timeline to modify the surfaces, and see the changes propagate through features later in the timeline.
