How to read mechanical engineering drawings ?

Best answer:

1. . Visible line: Indicates an edge is visible in relevant view.
2. . Hidden line: Indicates the edge is behind a face.
3. . Phantom line: Mostly used to indicate an alternate position of a moving part.
4. . Centre lines: drawn to indicate the exact geometric centre of the assembly.

FAQ

How do you read and interpret drawings?
Follow projection lines to read most dimensions. Lines drawn up or down indicate length and width, while those out to the side indicate height. Some drawings might place the dimensions directly on the side of the object if it’s clear in the drawing what side that dimension refers to.

How can I improve my engineering drawing reading skills?

1. Tip #1: Dimension only critical & measurable features.
2. Tip #2: Communicate hole tapping needs with thread size and depth.
3. Tip #3: Consolidate call-outs when multiples of the same feature exist in a view.
4. Tip #4: Communicate assembly intent of critical features.

What are the symbols used in engineering drawing?

What is the 3 most important parts of an engineering drawing?

1. Geometry – the shape of the object; represented as views; how the object will look when it is viewed from various angles, such as front, top, side, etc.
2. Dimensions – the size of the object is captured in accepted units.
3. Tolerances – the allowable variations for each dimension.

Is engineering drawing hard?
It is a kind of technical drawing with complete specifications for engineered items. Engineering drawing may be about technical drawings but it is one of the toughest subjects, ask any engineering student and you will know. A sound knowledge of drawing is vital otherwise its a tough road ahead with the subject.

Do I have to be good at drawing to be an engineer?
You do not have to be talented at drawing to become a civil engineer. But, it’s necessary to be able to use drawing software such as AutoCAD. Hand-drawing may be helpful when you design buildings, but most of the companies today use computers that can draw blueprints.
