4.2.1 Modeling implied motion

In this part the wiki introduce four types of model by using the preset function inside the Fusion 360.

Extrude

The first one is Extrude, this is a basic function that can be used on a lot of model making. By creating a base shape, and extrude it, that face will have volume to become a model. This is more about a simple extending.

Revolve

For this part, a revolve is another function that can make a face rotate around an axis to form a model. Instead of vertical stretch. This time it use an axis to create a seemly different model than what the original face is.

Sweep

Sweep is a bit more complex. A sweep is when a shape was created, and then use a path to let it “extrude” according to the path. It could be twisted, or finished at the end as a smaller face.

Loft

The last one is loft. The loft is when multiple faces with same or different shapes stacked, then connection them to create a model.

My turn

After reading the wiki, this is my attempt of making these models.

4.2.2 Mold making

This part, the wiki described how to check the model to make sure it is ok to make the mold. Important things like no negative space, anything have two bigger side and thin middle part cannot be present on the mold. For example, the left one in my practice is impossible.
