Pictorial Views

Dimensions Line Types

Drawing Clarity-Setting standards and norms in a drawing for a clear interpretation of the parts and assemblies.

Determine placement of the regular views.

Determine cutting plane lines and corresponding section views.

c. Determine detail size and descriptions.

1. Details should be labeled by a phantom line circle on the drawing where they occur.

2. Details can be placed in any convenient space on the drawing. Under the separated detail should be the name and scale of the detail.

Assess you knowledge of Drawing Clarity

Can you identify examples of these line types in a drawing:

- Object lines

- Hidden lines

- Dimmension lines

- Phantom lines

- Section lines

- Center lines

Can you identify the 6 regular drawing views and their location?

Can you identify the 3 commonly used pictorial views?

First Angle Projection and Third Angle Projection

Determine the language of the print, and whether it is drawn in first-angle projection or third-angle projection. The standard can be written in the title block or shown as a symbol.
