4.2 Exercise Reflection

4.2.1 Modeling Implied Motion

The purpose of this wiki page was to introduce how to create implied motion within Fusion 360 by using parametric molding techniques such as extrude, revolve, sweep, and loft.

• The Green-colored arc slot used extrusion to imply linear motion as this applies an extrude with symmetry, and also a fillet and draft.
• The Red-colored object used revolve to imply rotation of a shape about a linear axis. Which started with using spline and lines to create the shape, and also a fillet and draft.
• The Gold-colored lightning bolt used sweep to imply a shape along a curved path, which started with an ellipse and a spline in a “lightning bolt shape.
• The Copper-colored object utilized loft which changes the shape of the object for a certain path.  A hexagon and a circle were sketched in separate planes and lofted together.

4.2.2 

The purpose of this wiki was to understand mold making of a digital substitution model and how to identify undercuts, texture in the mold,  draft angles, and beveled corners, and how to modify the object orientation for the mold or possibly modifying the form.

For the first form, I had to rotate the object 90 degrees, to be able to create the mold, so that it doesn’t create any undercuts.

For the second one, I also had to rotate the object 90 degrees, so that it doesn’t create any undercuts.

For the third one, the mold came out really good, I didn’t have to rotate it, this mold will be half of the form since there is symmetry

For the fourth one, I had to rotate the object 90 degrees, so that it doesn’t create any undercuts in the mold as well.
