Are hidden lines shown in isometric drawings?

Usually only the visible surfaces of an object are drawn in isometric, with hidden lines left out. Although this is considered the preferred practice, there are always times when hidden lines are needed to clarify very complex isometric drawings.

Why hidden lines and center lines are used?

Hidden lines in a drawing represent the edges where surfaces meet but are not directly visible. Hidden lines are omitted from pictorial drawings unless they are needed to make the drawing clear.

What are center lines?

2.2 Center lines. Center lines denote a circular feature such as a shaft or a hole. A rectangular feature seen on an elevation of a drawing could be identified either as a circular feature or a rectangular feature. The center line is the method of quickly identifying the shape.

What do hidden lines in orthographic projection?

What do hidden lines in orthographic projections denote? Explanation: Hidden lines denote those parts which cannot be seen when viewing the object. They are used when there are holes or slots in the object if they cannot be viewed directly. Change of plane is indicated by outlines.

Can hidden lines overlap?

The overlapped areas of the objects that lie behind (referred to as the background) are drawn as hidden lines. Objects overlapping each other this manner are said to be involved in a “hide situation”. Any closed contour on a contour layer or a non-mechanical layer can be selected as a foreground object.

How is a Centre line represented in an engineering drawing?

Centerlines indicate a circular feature on a drawing. In 2D, most circular features look exactly the same as features with non-circular geometry. The only way to tell them apart is by adding a centerline, which represents their central axis and confirms their geometry.
