Lecture on the 30th and 31st of May 2023.

The concepts we covered throughout the lecture syllabus are

Sketch

11. Trimming Sketches (Select trim, Select unwanted segments, unselected area or backspace to finish)

12. Introduction to Constraints (Constraints setting) (Sketch menu) (Auto Constraint) (Show all VS Selection-based)

13. Adding and Removing Constraints (Select sketch element first, Select constraint type after) (Perpendicular, Midpoint, Endpoint, Point Locks) (Three ways to remove constraints 1) Unlock, 2) Disconnect, 3) Delete Constraint (Button))

14. Editing sketch dimensions (Select sketch, Calculator calculate dimension number) (Select distance type, left from icon) (Three types of distance 1) Horizontal, Vertical, Connected or unconnected) (Define angles)

15. Types of constraints (At least two lines, Constraint menu, not always connected) (1) Parallel, 2) Tangent, 3) Other elements(Shapes) 4) Midpoint (Endpoint + Midpoint), 5) Concentric (Arc + Circle), 6) Horizontal+Vertical(One or more), 7) Auto-Constraints (Just Sketch), 8) Equal-Constraints (Many), 9) Symmetry-Constraints (Two lines + Axis-line), 10) Lock Constraint (Line + Lock, colour)

16. Using pattern constraints (Pattern Changing, break pattern for individual change)

17. Making Construction Geometries (Select Sketch, Select one sketch element, Make construction, dashed line, to return-Make Regular)

18. Defining Sketch Planes (Faces of orientation cube, press the space bar, select the face, select the space by touch-screen)

Final rewards:

Using Chat GPT-4 to generate precise shapes

11. Trimming Sketches (Select trim, Select unwanted segments, unselected area or backspace to finish) (Only group 1)

>>> Again explained how to trim (Remove) sketches, however minded to calculate contacting points of sketch lines such as intersections, since the system recognizes them as different parts, and it is very important. Furthermore explained the action with the mathematical concept (Definition, Principle) of removing equations and functions or the m plotted in specific areas, giving conditions.

12. Introduction to Constraints (Constraints setting) (Sketch menu) (Auto Constraint) (Show all VS Selection-based)

    >>> Used the mathematical concept (Definition, Principle) of identifying the information of right-angled geometric features. 

>>> Explained with the focus on modifying standardization throughout the designing process.

13. Adding and Removing Constraints (Select sketch element first, Select constraint type after) (Perpendicular, Midpoint, Endpoint, Point Locks) (Three ways to remove constraints 1) Unlock, 2) Disconnect, 3) Delete Constraint (Button))

>>> Explained the difference between Locked/ Unlocked and Connected/ Disconnected. Plus breaking and forming them through the Trim tool. Locking a point causes a point on a line to stick on the cartesian plate coordinate given, and only other connected parts with certain points are moveable. For the Connection tool, it is the condition that causes a sketch line to become independent to freely move and rotate. 

Then covering Number 14,15,16,17 from our Modelling Syllabus, we learned and explored constraints named “Parallel”, ”Perpendicular”, “Tangent”, “Coincident”, “Midpoint”, “Concentric”, “Horizontal/Vertical”, “Equal”, “Symmetry”, “Disconnect”, “Lock”, “Make Construction”. Plus the importance of defining the independent sketch object selected first, since it becomes the standard axis of actions given above, with a certain direction.. ( “Parallel”, ”Perpendicular”, “Tangent”, “Coincident”, “Midpoint”, “Concentric”, “Horizontal/Vertical”, “Equal”, “Symmetry”)

14. Editing sketch dimensions (Select sketch, Calculator calculate dimension number) (Select distance type, left from icon) (Three types of distance 1) Horizontal, Vertical, Connected or unconnected) (Define angles)

15. Types of constraints (At least two lines, Constraint menu, not always connected) (1) Parallel, 2) Tangent, 3) Other elements(Shapes) 4) Midpoint (Endpoint + Midpoint), 5) Concentric (Arc + Circle), 6) Horizontal+Vertical(One or more), 7) Auto-Constraints (Just Sketch), 8) Equal-Constraints (Many), 9) Symmetry-Constraints (Two lines + Axis-line), 10) Lock Constraint (Line + Lock, colour)

    >>> Used the mathematical concept (Definition, Principle) of the perpendicular foot between two lines, even with extended dash lines. 

    >>> Used the mathematical concept (Definition, Principle) of the uniqueness of a cartesian coordinate point to explain “Lock” in Constraints.

    >>> Used the mathematical concept (Definition, Principle) of translation with a translation vector while explaining moving sketches by constraints.

    >>> Used the mathematical concept (Definition, Principle) of the Relation between Vectors and Scalars on a 2D Cartesian Plate, while explaining the tool “Equal” and “Parallel”, by the conditions required for a scalar to become the same vector with another. That only sharing the same magnitude insists that two scalars are equal, however when the directions of each vector with equal scalars are parallel, sharing the same direction, they become equivalent vectors. 

    >>> Explained the “Perpendicular” tool with Perpendicular and Parallel relations between vectors(Lines)

    >>> Explained the dilation of sketch figures forming tangents by the mathematical principle of Dilation and Tangent and Instantaneous Rate of Change which forms in the point of sketches meeting each other.

    >>> Explained placing two or more lines on a coincident by using the tool “Coincident” by method on a 2D cartesian plate, by the mathematical principle of the equivalent of functions.

    >>> Explained plotting a new point constraint by using the tool “Midpoint”, and used the mathematical principle of Midpoints on a line.

    >>> Explained plotting various polygons to circles and ellipses with concentric methods through the mathematical principle of concentric. By the definition of concentric in Geometry, the objects are said to be concentric when they share a common centre. Circles, spheres, regular polyhedra, and regular polygons are concentric as they share the same centre point. 

    >>> Explained changing the angles of drawn lines using the tool “Horizontal/Vertical”. The system recognizes the closest angle by dividing portions between diagonal lines of each quadrant (y=x and y=-x) and discriminates whether it would become horizontal or vertical, meaning parallel to the x-axis if smaller than 45degrees, and parallel to the y-axis if larger than 45degrees and smaller that 135degrees. 

>>> Explained the tool “Symmetry” by the mathematical concepts of rotation and symmetric relations. 

    >>> Explained the tools “Connect” and “Disconnect” by using the mathematical principle of Continuity Relations of a function and Discontinuity Relations of a function. 

16. Using pattern constraints (Pattern Changing, break pattern for individual change)

>>> Explained the pattern constraints with the mathematical principle of Sequence and Series, plus all mathematical tools used above to explain. How to generate pattern constraints, focusing on the relations between each constraint and patterns.

17. Making Construction Geometries (Select Sketch, Select one sketch element, Make construction, dashed line, to return-Make Regular)

    >>>Explained the tool “Make Regular” by Dashed lines in mathematics, used for standardization and design planning.

18. Defining Sketch Planes (Faces of orientation cube, press the space bar, select the face, select the space by touch-screen)

    >>>Explained the usage of orientation cube and the importance of the mathematical concept of 3D planes in vectors and scalars + Cubes + Mathematical Intuition vs Standardization. Also highlighted the importance of designing with standardization, instead of being dependent on intuition while designing, which requires proper frontal face faced on the design plane.

For the last, as we accomplished our objectives of finishing the sketch in 3weeks, as a reward, we learned and discussed using Chat-GPT to generate a function through an input visual source and plot it on the Desmos programme, for fun and enthusiasm in Artificial Knowledge also.

Throughout three weeks, our club members fully mastered sketching skills through Sharpr3D, and will take more lessons during their summer holidays, extending our knowledge to designing 3D spaces. Great effort everyone!
