Intro To Engineering Design Quiz Sept. 11

These lines are used to show interior detail that is not visible from the outside of the part. The term "hidden" accurately describes this purpose, as it implies that the details are concealed or not easily seen.

The lines being described as "thick and dark" suggests that they are being used to outline or define something. This aligns with the definition of an object, as objects can be visually defined by lines. Therefore, the correct answer is object.

Center lines are used to define the center of arcs, circles, or symmetrical parts. They are half as thick as an object line. Center lines are important in technical drawings as they provide a clear indication of the center point of a shape or object. They help in accurately positioning and aligning elements in a design.

The correct answer is "construction". Construction lines are lightly drawn lines used as guides to help draw all other lines and shapes properly. They provide a framework or structure for the drawing and are often temporary, meant to be erased or hidden once the final drawing is complete.

Section lines are used to define where there is material after a part of the object is cut away. They are typically drawn as evenly spaced parallel lines that indicate the presence of solid material in the sectioned area. By using section lines, engineers and designers can clearly communicate the internal structure of an object or component in technical drawings. This helps in understanding how the object is assembled and how different parts interact with each other.

The proper way to make a hole in Inventor is by first creating a point at the center of the desired location and then using the hole command. This method ensures that the hole is accurately placed and aligned with the part.

Dimension lines are used to show the measurements or dimensions of an object. They indicate the distance between two points on an object and are typically represented by a straight line with arrowheads at each end. Dimension lines are important in technical drawings and blueprints as they provide accurate information about the size and proportions of an object.

Extension lines are used to show where a dimension starts and stops on an object. They are typically drawn 1/16" away from the part to avoid confusion with the object lines.

A design brief is a document that provides a concise overview of the problem at hand. It outlines the key details and objectives of the project, including the scope, target audience, and desired outcomes. This document serves as a reference for designers and stakeholders to ensure a shared understanding of the problem and guide the design process. It helps in aligning everyone involved and sets the foundation for successful problem-solving and design solutions.

A short break is a freehand drawn line that shows where a part is broken to reveal detail behind the part. This line is shorter in length compared to a long break, which means it indicates a smaller break or opening in the object. The short break helps to visually represent the presence of a break or opening in a part, allowing the viewer to understand the internal details or components that are hidden behind it.

A long break line is used to shorten very long objects that do not change in detail. This means that when there is a long object in a drawing that remains the same throughout, a long break line is used to represent it in a shortened form. This helps to save space on the drawing and make it easier to understand.

The correct answer is Paul McCready. In the Gossamer condor video, Paul McCready is mentioned as the designer of the aircraft.

Leader lines are used to indicate the location of a feature or dimension. They are typically drawn as a thin line with an arrowhead at one end. Leader lines are used to connect a note or dimension to a specific feature on a drawing, such as an arc, circle, or detail. They help to clarify the relationship between the feature and the associated dimension or note.
