Orthographic Writing Chapter 5 Quiz

The process of adjusting the orientation of an object's view in an orthographic projection to ensure clarity and consistency.

A view of an object where the selected portion is shown in a larger scale than the original view.

Lines indicating the intersection of surfaces that are hidden due to fillets or rounds. These lines are added to the projection, even though they don't physically exist, to improve understanding of the object's shape.

A convention used in orthographic projection to represent the shape and orientation of an object. This convention helps communicate the intended view clearly.

A view representing portions of a part that have features needing clarification.

A partial view showing only half of the part, often utilizing a line of symmetry.

A view that displays features needing clarification, often focusing on specific details.

A view which shows the object in its true form, as if projected onto a plane.

A view that represents the shape of the object from the side.

A view that shows the object in its complete form.

A line that indicates the symmetry of an object, often dividing it into two equal halves.

A common practice in orthographic drawing that deviates from strict projection rules to improve readability, dimensioning, and drawing efficiency.

A representation of an object's multiple views (front, top, side) used in technical drawings to illustrate its shape and structure.

An alternative placement of the side view next to the top view when the object's height is significantly smaller than its depth. This saves space and improves clarity.

A side view that omits a feature that cannot be seen clearly from the chosen viewing direction, simplifying the drawing and enhancing clarity.

Dimension figures are placed so that they can be read from the bottom and right side of the drawing.

Dimension figures are placed so that they can be read from the bottom of the drawing.

The unit of measurement for length is millimeters, written without the "mm" symbol.

The unit of measurement for angles is degrees, denoted by a small circle symbol (o).

Notes providing additional detail about a feature should be placed near the feature and outside the view.

Notes should always be written horizontally for easy readability.

Adding size and location information to a drawing, making it suitable for production.

Dimension figures should be placed close to the feature they are describing to avoid confusion.

Lines that indicate the location on a feature being dimensioned, extending from the feature to the dimension line.

Lines with arrowheads indicating the direction and extent of a dimension, containing dimension figures.

Lines connected to features with a note to specify details like drilling information or radii.

Numbers placed on dimension lines to indicate the size or distance.

A system of measurement using units like millimeters and centimeters.

A system of measurement using units like inches and fractions of inches.

A set of standards (like ISO and JIS) that define rules for dimensioning in the metric system.

A curved shape created by joining two or more arcs, requiring defined radii and center locations.

A three-dimensional object with circular cross-sections of equal diameter, defined by its diameter and length.

A circular opening in a part, characterized by its diameter and depth.

A chamfer is a bevel or angled edge created by cutting away a corner.

The measurement of the distance between two points or the size of an object.

The measurement of the position of an object or feature.

A dimension line with a circular arc, where the center of the arc is at the vertex of the angle.

A dimension line indicating the radius of an arc, marked with a 'R' before the numerical value.

The dimension line and arrowhead are placed inside the arc to indicate the radius, ensuring there is sufficient space.

The leader line connecting the dimension line to the arc must be radial, at an angle between 30 degrees and 60 degrees.

When the center of the arc is outside the drawing sheet or interferes with other views, a foreshortened radial dimension line is used.

A note indicating the radius of fillets and rounds if they are uniform across the part. It's optional to dimension them individually, but it is necessary to add the note specifying the radius.
