Using external constraints (Should know)

It's rare that all the features of the part we want to design are in the same two-dimensional plane.

Imagine that we want to add holes to the top surface of the part we designed in the Modeling with constraints (Must know) recipe as shown in the following screenshot. To do this, we need a way to associate a new sketch with the top face of the part.

An external constraint gives us a way to relate elements of our sketch to entities that are not in the sketch itself, like the face of a part.

Using external constraints (Should know)

In this recipe we'll also show how features in a sketch can be related to an existing object.

Along the way, we'll also ...
