Select three types of lines that engineers use to help represent the shape of a design in a sketch.

object lines

leader lines

center lines

extension lines

dimension lines

hidden lines

Answers

Answer:

object, hidden, and center lines

Explanation:

Among the given alternatives, we prefer to dimension to visible lines.

When creating technical drawings, dimensions are typically placed on visible lines. Visible lines represent the visible edges or outlines of an object or part. These lines are used to depict the physical features of the object that are visible to the eye. By dimensioning to visible lines, we ensure that the measurements are accurately associated with the visible features of the object.

This helps to provide clear and unambiguous information about the size and location of the features being dimensioned. Dimensions on hidden lines or center lines may not accurately represent the physical dimensions of the visible features and can lead to confusion or misinterpretation. Therefore, visible lines are the preferred choice for dimensioning in technical drawings.

Which sentence highlights the use of coherence and unity in the building design?

Amelia creates a building design where she includes many themes and variations in the shapes and patterns used. The building remains asymmetrical. Clara created a building design that has rhythm, two themes, contrast, and balance. Sam’s building design, on the other hand, has too many elements and themes.

Answers

The sentence that highlights the use of coherence and unity is "Clara created a building design that has rhythm, two themes, contrast, and balance."

What are coherence and unity in design?

In design, coherence implies all elements included are logical or work together, which means there is a balance in the elements.

On the other hand, unity implies the elements work as a "whole" despite being different.

What sentence illustrate these principles?

Clara's sentence illustrate these principles because even when she included different elements all of them seem to have a logical order and they word together to create a unit.
