# Modeling Techniques
# Extrusion
- What is it
- different ways to use it
- common problems
– Extrusion created geometry from a source component and connects the new geo to the source geo
– It’s a good way to expand the shape especially in the beginning phases of your model
- along normal
–
# Common problems
- Laminate faces
- edge poles
- can be limiting in the shapes you can make
- scaling
# Mirroring
– What is mirroring in CG?
–
- a copy and matrix transform of target 3D data
– When might it be useful?
