Technical Drawing Concepts

A drawing that shows multiple views of an object from different angles.

A standard practice where views are arranged in a specific order to ensure clarity and easy understanding.

The top view of an object in a multiview drawing is positioned above the front view.

The right side view of an object in a multiview drawing is positioned to the right of the front view.

A view drawn to show a specific feature of an object that is not visible in the principal views.

The main views of an object in a multiview drawing used to define overall shape and size.

Six standard views used to show an object completely: front, top, left side, right side, rear, and bottom.

A view of an object that is cut open to reveal internal details and features.

Shows how an object looks when viewed from six directions, as if the object were enclosed in a glass box.

A view that shows the object from above, as if you were looking down on it.

A view that shows the object from the front, as if you were standing directly in front of it.

A view that shows the object from the side, as if you were standing to the right of it.

A technique used in engineering drawings where the observer is assumed to be in front of the object.

The true width of an angled surface is shown in the top and side views, but it does not show the true length.

The true length of an angled surface is shown in the front view, but it does not show the true width.

An imaginary cut through an object, perpendicular to the line of sight, used to reveal internal features.

Lines used to represent the cut surface of a section, often indicating the material type.

A sectional view where the cutting plane goes completely through the object.

A sectional view where the cutting plane is only partially passed through the object, typically used for symmetrical objects.

A sectional view used for thin objects like sheet metal or gaskets, depicted using solid black lines.

Identifying letters used to label sections, indicating their position on the drawing.

Arrows indicating the direction of sight when viewing a sectional view, placed at the ends of the cutting-plane line.

A section where the cutting plane rotates 90 degrees, showing features like spokes or ribs. Used for clear representation of internal shapes.

A section moved to a new location on the drawing for clarity and enlargement. Used when the original placement is insufficient.

A section with a stepped or offset cutting plane, used when features lie in multiple planes. Shows intersection of features across different levels.

A section showing a small portion of an object, used when a full section isn't needed. Defined by break lines.

Shortening a long, uniform object to show details at a larger scale. Uses special break lines to indicate shortening.

Internal structures added to objects to increase strength and rigidity.

A method for understanding drawings by examining the shape, size, and other information on the print.

Practice reading prints to build proficiency and avoid costly mistakes.

The use of lines to represent hidden edges or features of an object that are not visible in the main views.
