Figure 3.30 - Full model with both sides
Since they will be different objects, use a CTRL+J to join them, and later
apply a Merge using the distance option. It removes all duplicated
vertices.
Tip: A trick used by some artists to apply a mirror using the Scale
transformation consists of a scale with -100% of the object size. For
instance, select the object and press the S key. Type -1 as the factor to
get a mirror image of that model.
What is next?
The extrude is an incredible tool and is by far one of the highlights of this
chapter, but it won't solve all modeling challenges alone. You will still
need additional tools to create complex models. But, in most projects,
you use extrudes to build the vast majority of a model structure.
