How are engineering drawings prepared in real life?

How are engineering drawings prepared in real life?

Usually engineering drawings (of real life objects) are prepared in three stages; sketches, handdrafts and detail drawings. This sequence is not very binding but most workers find it very useful to work in that order. 2.3.1 Sketches

Which is the best view for an engineering drawing?

Engineers stay true to the dimensions rather than optical illusions. This is the bread and butter of an engineering drawing. An orthographic view or orthographic projection is a way of representing a 3D object in 2 dimensions. Thus, a 2D view has to convey everything necessary for part production.

What is a perspective view in engineering drawing?

A perspective view is an artistic one that represents an object as it seems to the eye. Engineers stay true to the dimensions rather than optical illusions. This is the bread and butter of an engineering drawing. An orthographic view or orthographic projection is a way of representing a 3D object in 2 dimensions.

What is the difference between drawing and sketching in engineering?

The purpose of this guide is to give you the basics of engineering sketching and drawing. We will treat “sketching” and “drawing” as one. “Sketching” generally means freehand drawing. “Drawing” usually means using drawing instruments, from compasses to computers to bring precision to the drawings. This is just an introduction.

Which is the best way to draw an engineering object?

Any engineering drawing should show everything: a complete understanding of the object should be possible from the drawing. If the isometric drawing can show all details and all dimensions on one drawing, it is ideal. One can pack a great deal of information into an isometric drawing.

What is the ASME standard for engineering drawing?

ASME Y14.100; “Engineering Drawing Practices”. This Standard establishes the essential requirements and reference documents applicable to the preparation and revision of engineering drawings and associated lists. It is essential that this Standard be used in close conjunction with ASME Y14.24, ASME Y14.34M, and ASME Y14.35M.
