How are modification drawings used in the engineering field?
Modification drawings delineate changes to delivered items, stockable items (e.g., Standard Part Drawing of honeycomb panel blanks), assemblies, installations, or systems. Drawings are prepared to add, remove, or rework items, equipment installations, or systems to satisfy the using activity’s requirements.
What is the purpose of dimensioning in drawing?
The purpose of dimensioning is to provide a clear and complete description of an object. A complete set of dimensions will permit only one interpretation needed to construct the part. Dimensioning should follow these guidelines. Accuracy: correct values must be given. Clearness: dimensions must be placed in appropriate positions.
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.
Which is the left side of an engineering drawing?
The left hand side view is drawn on the left hand side of the front view. Similarly, the top view (plan) is drawn at the top of the front view. Engineering drawings, being one of the many forms of technical communication, have to fulfill some accepted standards.
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.
