Technical Illustrator Interview Questions and Answers

First angle and third angle projection are two different methods used in technical drawing to represent a 3D object on a 2D surface.

• First angle projection is commonly used in Europe and Asia, while third angle projection is commonly used in North America.

• In first angle projection, the object is placed in the first quadrant and the views are projected onto the planes surrounding the object.

• In third angle projection, the object is placed in the third quadrant and the views are ...read more

First angle and third angle of projection are two different methods of creating orthographic projections of a 3D object.

• First angle projection is commonly used in Europe and Asia, while third angle projection is commonly used in North America.

• In first angle projection, the object is placed in front of the viewing plane and the views are projected onto the planes behind it.

• In third angle projection, the object is placed behind the viewing plane and the views are projected onto...read more

Control surfaces in aircraft are movable surfaces on the wings and tail that help control the aircraft's movement and attitude.

• Control surfaces include ailerons, elevators, rudder, flaps, and spoilers

• Ailerons are located on the trailing edge of the wings and control roll movement

• Elevators are located on the horizontal tail and control pitch movement

• Rudder is located on the vertical tail and controls yaw movement

• Flaps are located on the wings and help with takeoff and landing

• S...read more

To convert 2D projection to isometric view, use a 30-degree angle and draw lines at 120-degree angles.

• Choose a 30-degree angle for the isometric view

• Draw lines at 120-degree angles to create the isometric view

• Ensure that all lines are parallel and equally spaced

• Add shading and texture to enhance the 3D effect

2D is flat while 3D has depth and volume.

• 2D is limited to two dimensions while 3D has three dimensions.

• 2D is often used for technical drawings and schematics while 3D is used for modeling and animation.

• 2D is easier to create and edit while 3D requires more advanced software and skills.

• Examples of 2D include blueprints, floor plans, and circuit diagrams while examples of 3D include video games, movies, and product prototypes.
