example it the part is really 8" in depth you would make the detph 4" (1/2 scale) for this 3D Cabinet view. Cabinet looks more realistic 3d view.

NO because they are the lightest lines on a drawing... only for our references and made light so they can be earsed easy or not seen much.

Dimension lines are not drawn to the same weight as object lines. In technical drawings, dimension lines are typically drawn with a thinner and lighter weight compared to object lines. This is done to differentiate them from the main features of the drawing and to avoid confusion. By using a lighter weight, dimension lines are visually separated and allow for clear and accurate measurements to be taken from the drawing.

Engineers provide technical and managerial leadership in industry and government. They are responsible for the design and development of new products. They also plan structures and highways. Therefore, the correct answer is "All of the above and below."

The whole number divisions on an architect's scale represent feet. This means that each whole number on the scale corresponds to one foot in real-life measurements. Architects use these scales to accurately represent measurements and proportions in their drawings and designs.

In a unidirectional dimensioning system, all dimensions are read from the bottom of the page. This means that the measurements are taken starting from the bottom and moving upwards. This system is commonly used in technical drawings and engineering designs to ensure consistency and clarity in dimensioning.

Floor plans are commonly drawn to scale in order to accurately represent the dimensions and layout of a building or space. The scale of 1/4" = 1'-0" means that every 1/4 inch on the drawing represents 1 foot in real life. This scale allows architects, designers, and builders to accurately visualize and plan the construction or renovation of a space. By using a consistent scale, it ensures that all measurements and proportions are accurately represented on the floor plan. Therefore, the statement that floor plans are most commonly drawn at a scale of 1/4" = 1'-0" is true.
