Multiview Drawings

You will select one of your puzzle cube parts to draw.

Select and draw the best front view, then project the top and right side views

2.1.A LineConventions

Line Conventions

Lines of varying style and thickness are used in specific ways to develop and communicate graphic messages about an object’s geometry. The next few slides show some basic line conventions and their use

A front view refers to the view that typically shows the longest dimension and the most distinctive shape. For instance, in this context, the best front view of a vehicle would be one of the sides (driver or passenger).

Guidelines for Selecting a Front View

Selecting the correct front view tips:

Shows the longest dimension
Shows the best shape and characteristic contours
Hides the fewest edges and features
Displays the most stable and natural position

Line Conventions (Types)

Line conventions are rules that professionals use to standardize the way lines are displayed on technical drawings. Lines used in orthographic projections on multiview drawings are differentiated by weight (thick/thin, heavy/light) and by style (solid, dashed, broken). Lines of varying style and thickness are used in specific ways to graphically communicate information about an object’s geometry.

Construction Line - Lightly drawn line used to guide drawing other lines and shapes

Object Line - A heavy solid line used to represent the outline of an object

Hidden Line - A Heavy dashed line type that represents an edge that is not directly visible

Centerline - A line that defines the center of arcs, circles, or symmetrical parts. A center line is half as thick as an object line

Centerlines and Center Marks

When indicating the center point of a circle or arc, two perpendicular centerlines are combined into a center mark. A center mark should be placed on the view where the feature appears as a circle or arc. A centerline is used to show the center between two lines or edges or to show that a part is symmetrical. Figure 6 shows an example of the use of both a center mark and a centerline.
