Engineering Design 1 - Week 18 Lecture - Assembly Drawings

Countersinks

A conical hole that allows the head of a screw or bolt to sit flush with or below the surface, BSI Abbreviation: CSK.

Smart Dimension

A feature in SolidWorks used to create dimensions using the Annotation toolbar.

Bill of Materials

A listing of parts in an assembly drawing, including quantity and descriptions.

Exploded View

A view that shows the assembly with parts separated to illustrate how they fit together.

Hatching Patterns

Used to differentiate different types of components in section views.

Section View

A drawing view that shows internal features of an object as if it has been cut through.

Item References

Used to identify parts in an assembly, often with balloons in the drawing.

Assembly Drawing

A drawing that illustrates the arrangement and assembly of parts together.

Auxiliary dimensions

Dimensions added for reference only without affecting the overall dimensions of the part.

Exploded View Guidelines

Best practices for creating exploded views that clearly show the spatial relationships and assembly sequence of parts.

Item Referencing in Drawings

The process of labeling components in an assembly with unique identifiers, often represented with balloons connected to the corresponding items.

Labeling in Exploded Views

The technique of adding labels or numbers to parts in an exploded view to enhance clarity and understanding of the assembly process.

Directional Arrows in Exploded Views

Using arrows to indicate the direction in which parts need to be moved to assemble them back together.

Reference Numbers for Parts

Unique numbers assigned to each part in item references, facilitating identification in the assembly drawing.

Clear Representation of Components in Exploded Views

Ensuring all parts are visible and distinguishable for easier understanding of how they fit and work together.
