Study Notes

Introduction to Design

Design is the art of discovering new things and sharing knowledge.
It involves learning, teaching, breaking, making, seeing, and showing.

2D and 3D Drawings

2D drawings represent objects with two dimensions: length and width.
3D drawings represent objects with three dimensions: length, width, and height.
2D drawings have no depth, whereas 3D drawings have a life-like representation.

Dimension Tools

Dimension tools are used to change the size of drawings.
You can create horizontal, vertical, aligned, and radial dimensions with the DIM command.

3D Extrusion Tools

The Extrude tool creates a 3D shape from a 2D shape by defining various parameters.
Extrusion takes a portion of a mesh and extends it in a certain direction.

Tinkercad

Tinkercad is a powerful and easy-to-use tool for creating digital designs that can be 3D printed.
It offers guided lessons to teach the basics of Tinkercad and more complex modeling techniques.

Tinkercad Interface

The Workplane is the surface where designs are created, resembling a blank sheet of graph paper.
The menu bar is located at the top of the screen, providing various actions.
The Viewcube and navigation buttons are located to the left of the Workplane.
The Shapes menu is located to the right of the Workplane.

Exploring the Workplane

The Workplane has 1 cm "major grid lines" and 1 mm "minor grid lines".
The Edit grid button allows changing the units of the design.

The Viewcube

The view in Tinkercad is called the camera, using movie camera terms: tilt, rotate, pan, and zoom.
The Viewcube helps tilt and rotate the camera.

Shapes can be moved from the menu to the Workplane by clicking and dragging.

Resizing Shapes

Shapes can be resized in various ways after being placed on the Workplane.

Translation

Translation is changing an object's position without rotating or changing its size.
Translating an object along the X-axis moves it left or right on the Workplane.
Translating an object along the Y-axis moves it near or far from the Workplane.
Translating an object along the Z-axis lifts it up or down from the Workplane.

Boolean Operations

Boolean operations combine shapes into a new shape.
Boolean addition adds one shape to another.
Boolean subtraction turns one shape into a negative space, removing material from another.

Selecting Multiple Shapes

The Band Selection tool selects multiple shapes by drawing a box around them.

Grouping Shapes

Grouping shapes combines them into one complex shape using Boolean operations.
This allows creating complex shapes with solids and holes.

Challenges

The first challenge is to navigate around Tinkercad and view hints from the optimal angle to reveal a hidden message.
