How do you represent a sectioned surface on a drawing?
A sectioned surface is represented by drawing thick lines at angle 45° to the drawing on the sectioned surface, (this is done with the use of a tee square and 45° set square when drawn on a t board).
What are section lines used to indicate?
(Phantom or Hidden linetype) Page 2 of 11 Page 3 Technical Drawing and Design Section View Fundamentals Work Packet 3 Section Lines: Used to indicate where the cutting plane cuts the material. Section lines are thin and the symbols (type of lines) are chosen according to the material of the object.
What is a removed section view?
The removed section view is a zero-thickness slice through the model showing only cut edges and hatching perpendicular to the cutting line. ... It's easy, just select two opposed model edges and a view is created perpendicular to the section line, eliminating the need to create any additional construction geometry.
When and why is a section view necessary?
In which case, the direction of sight is towards one half of the object. The other half is then mentally discarded. Drafters use sectional views to improve the clarity of complex objects when internal surfaces result in too many hidden lines. Special conventions are used to make a sectional view easy to understand.
What is the difference between a half and full section view?
2What is the difference between a half and a full section? -A full section view is the full section. The half section view is half of the section. It is used when the object is symmetrical in both inside and outside details. One-half of the object is sectioned and the other half is shown as a standard view.
What is a broken-out section?
A broken-out section is part of an existing drawing view, that is used to remove material to a specified depth in order to expose inner details of a model. A closed profile, usually a spline, defines the broken-out section.
How do you draw a full section view?
A full section view is generated by running the cutting plane through the entire length of the object being sectioned.
- Click Layout tab Create View panel Section drop-down Full. ...
- Click the view you want to use as the parent view. ...
- Click in the drawing area to indicate the start point of the section line.

Are there hidden lines in section views?
Section views do not include hidden lines. Any material cut when a section view is defined is hatched using section lines.
What is an aligned section view?
An aligned section view / cut is a view created from a cutting profile defined from non parallel planes. In order to include in a section certain angled elements, the cutting plane may be bent so as to pass through those features. The plane and feature are then imagined to be revolved into the original plane.
What is a section line in engineering?
section – are thin lines in a pattern (pattern determined by the material being "cut" or "sectioned") used to indicate surfaces in section views resulting from "cutting". Section lines are commonly referred to as "cross-hatching".
