Session 3 8th

Why is the Sketch Tool more powerful than using basic shapes in 3D design?

• It draws faster

• It allows more freedom for precise custom shapes like holes and curves

• It can color the design

• It works only with squares and rectangles

In the context of robots, what are 'links' most similar to in the human body?

• Fingers

• Bones

• Muscles

• Nerves

Which of the following tasks would require advanced 3D design skills rather than basic shapes?

• Making a ball

• Drawing a cube

• Creating a sensor mount with angled holes

• Designing a smiley face keychain

What is the main advantage of designing robot parts in 3D first?

• You can skip manufacturing

• You can animate the robot

• You can visualize, test fit, and 3D print parts accurately

• You can color the parts

What feature of 3D models makes them different from 2D shapes?

• They use only curves

• They are black and white

• They have depth (height, width, and length)

• They cannot be rotated

Which part is not typically prototyped using advanced 3D design?

• Arduino casings

• Custom gears

• LED light programs

• Sensor brackets

What happens when you click 'Finish Sketch' in TinkerCAD?

• Your robot starts to move

• The sketch turns into a 3D object

• The program shuts down

• The shape gets deleted

Why is it important to choose the correct plane (top, front, side) before sketching in 3D software?

• It saves the file in color

• It decides how your model prints

• It determines how the shape is built in space

• It changes the font

What is one benefit of prototyping a robotic part before manufacturing?

• You don’t need to use CAD

• You can test functionality and fit without wasting material

• It makes robots faster

• It improves battery life

Which of the following tools is most useful for drawing curved outlines in the Sketch Tool?

• Eraser

• Rectangle tool

• Arc tool

• Color picker
