Half Section  
 

 

Half Section of the Collet Fixture Solid Model.

The cutting plane has a right angle bend and is aligned with the center of the large vertical through hole. The cutting plane also goes through the center of the small pin hole on the side of the collet fixture. The right front quarter of the object is then assumed to be removed, showing the remaining part as a half section.




Half Section Drawing of the Collet Fixture.

The cutting plane line is drawn on the top view indicating the position of the right angle bent cutting plane. The half section is shown in the front view. The part of the object that is solid at the cutting plane is shown crosshatched in the front. The part of the object that is hollow at the cutting plane is not croshatched, but the visible background lines of these features are drawn. Her the visible background features include the back of the large vertical through hole, the small pin hole, and the half-slot on the end of the fixture.




Alternate Half Section Drawing of the Collet Fixture.

Hidden line and centerline representations are optional on the non-sectioned side of a half section view. Here, hidden lines and centerlines have been omitted in the non-sectioned side of the front view of the collet fixture. This less detailed approach may be justified because of the symmetric nature of the collet fixture. For this case, a centerline is used to indicate the separation between the right sectioned side and the left non-sectioned side of the front view.
