Lecture of 9th of August 2023

4. Project 

5. Loft: Transitions between sketches or profiles (Requires at least two sketches (Angle doesn’t matter), Select base sketch, create a copy of sketch (Not mandatory), Select sketches, click loft tool) 

6. Draft angle: (Extrude, estimate Draft angle value)

7. Shell: (Select surface, click shell tool, estimate shell(wall) thickness value) (Case1: Plastic) (Case 2: Cup design) (Shell out faces vs Shell out whole body)

8. Helixes (Basically Revolve tool) (Least one sketch, Select axis, Click revolve, define height(Length) of rotation, define angle) (Thread tool: Bolt and Nuts)

4. Project 

1. Sketches (Require a sketch and a 3D object, Tap to select sketch, search for project tool, Tap to select bodies (Imprinted Body Edges / Sketches), Tap project)

2. Solids (Select the face of a solid, Select face to project, With the same logic, Edges to faces curves...)

>>> Used the mathematical concept of points projected on a derivative and instantaneous rate of change forming a curve. Plus highlighted the fact that the surface of the sketch does not bend over the surface of the object, projecting it directly in straight lines.

After teaching the syllabus, some students were yet unsure about the previous contents, so revised the prior lecture.

5. Loft: Transitions between sketches or profiles (Requires at least two sketches (Angle doesn’t matter), Select base sketch, create a copy of sketch (Not mandatory), Select sketches, click loft tool) 

>>> Used the mathematical concept of mathematical similarity of figures and differential quadrature method to show the filling and forming of the object through distinct surfaces. Also explained both relations to rotation in differential calculus and definite integration for understanding the fact of being a similar process of deriving results. Plus explained the carving tool for smoothing sharp cuts.

6. Draft angle: (Extrude, estimate Draft angle value)

>>> Used the mathematical concept of the angle between two vectors, cord, and trapezoid to explain the procedure. Precisely, the pivotal concept applied in this mechanism is the angle between a line and a plane, where the angle is adjusted changing the position of the plane itself. This may also be extended to the angle between two planes and its orientation.

7. Shell: (Select surface, click shell tool, estimate shell(wall) thickness value) (Case1: Plastic) (Case 2: Cup design) (Shell out faces vs Shell out whole body)

>>> Used the mathematical concept of similarity of mathematical figures extending to the ratio difference of similar three-dimensional figures. Explained by showing the creation progress of a cup for example.

8. Helixes (Basically Revolve tool) (Least one sketch, Select axis, Click revolve, define height(Length) of rotation, define angle) (Thread tool: Bolt and Nuts)

>>> Used the mathematical concept of trigonometric functions in three-dimensional space, forming a helix(spring). Explained in the order of concepts: Rotation of a circle forming a doughnut, (Mathematical concept of rotation of quadrature method) then stretching the doughnut, (Mathematical concept of stretch) then rotating the angle consistently until a sufficient amount of helixes are formed. This could later be merged with a bolt and nut to form a screw-based object.
