How are engineering drawings numbered?
All Engineering documents shall carry a unique identification number consisting of five groups: (1) a two letter prefix, (2) a three digit number, (3) a second three digit number, (4) a two digit suffix, and (5) the letter R, C, or E followed by one or two digits. These five components shall be separated by dashes.
What does drawing number mean?
The drawing number is used primarily for sheet to sheet linking, typically in, but not limited to; section details, section cuts, and detail callouts. Drawing Numbers are placed in CAD files, they consist of the discipline/sheet type designator followed by a hyphen and a number.
What information can you find on a mechanical drawing?
Mechanical systems drawing is a type of technical drawing that shows information about heating, ventilating, air conditioning and transportation around the building (Elevators or Lifts and Escalator).
Why drawings are numbered?
Drawing numbers should be given in all memoranda whenever drawings are transmitted. The drawing numbers are a positive means of identification, and they minimize potential difficulties if drawings become detached from the transmittal memoranda.
What is drawing in mechanical engineering?
Mechanical engineering drawings are technical and skilled drawings that help define and illustrate specific mechanical requirements and processes. They are engineering drawings specifically for mechanical purposes. These technical drawings help communicate problems and solutions that mechanical engineers experience.
What are the two elements of engineering drawing?
The two broad types of projections, both with several sub- classifications, are parallel projection and perspective projection. Projections. Orthographic projections: are drawn as multi view drawings, which show flat representations of principal views of the subject.
Is part number same as drawing number?
Part numbers and drawing numbers should be the same. Adding a table for design variations are not old school, but essential for R&D development/pre-production. Models can be revised; it is a good check for the “changing form fit and function?” question; that is if you are changing the model, the answer is likely “yes”.
How do you make a drawing number?
To do this: Run a drawing process for your single parts. In the Process properties dialog, use the Drawing number field to set your drawing number as needed, this will become the part number. Click OK to exit the Process properties dialog. Run a drawing process for your assemblies.
How do you create a part number system?
6 tips for creating part number schemes Don’t start part numbers with 0. Use as few letters as possible. Keep a consistent part number length and formatting, preferably on the short side. Don’t use spaces or characters as delimiters that will confuse software, like slashes, parentheses, or apostrophes.
Is engineering drawing hard?
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. It is an art because it involves a lot of drawing, that to complex form of drawing.
Why do you need to know about mechanical drawing?
It gives the design team the ability to combine ideas among each other and develop them into cohesive, yet elaborate, drawings consisting of dimensions and line work, allowing for a straightforward transition to computer aided design.
What is a plan view of a mechanical drawing?
A plan view is an orthographic projection of a 3-dimensional object from the position of a horizontal plane through the object. In other words, a plan is a section viewed from the top. Basically, a plan view is just another name for the top view of a 3D object.
How are construction drawings organized?
Drawings are always organized from most general to most specific or specialized. Since plans are most helpful to see the overall design of the project, they come first. Elevations and sections are a bit more specific and come next followed by details and schedules, which are the most specific type of drawings.
What is the number used for filing drawings called?
The drawing title and the drawing number are used for identification and filing purposes. Usually the number is unique to the drawing and is comprised of a code that contains information about the drawing such as the site, system, and type of drawing.
What is the order of construction drawings?
The General Order of Drawings in a Set of Construction Plans G for General Sheets: Cover sheet, plan index, and location plans. A for Site and Architectural Plans: Floor plans, ceiling plans, roof plans, elevations, sections, wall sections, and others, depending on the architect’s chosen level of detail.
What are the 2 types of drawing?
There are two types of drawings. The first is a drawing done without instruments, known as a sketch. The second is a drawing done with instruments, known as a final drawing. Sketch Final drawing Artistic drawings convey an idea, feeling, mood or situation.
How many types of mechanical drawing are there?
6 types of engineering drawings.
Does mechanical engineering have drawing?
All mechanical engineers are taught drafting. Thus, most engineers are skilled at making and interpreting these formal mechanical drawings.
How do you read mechanical engineering drawings?
Title block Name and address of the company or agency who prepared or owns the drawing. Part number and description. Material. Mass. Finish. General tolerances. Projection details. Scale used in the drawing.
What is RF in engineering drawing?
Explanation: Representative fraction is the ratio of the length of the object represented on drawing to the actual length of the object represented. So the representative factor is that dimension in drawing to actual dimension. R.F.
Why engineering drawing is called universal language?
With the help of this, engineers living at every corner of the world can understand the need of their customers and engineer the product accordingly. Since every engineer, irrespective of their languages can read and understand it, drawing is said to be Universal language or Language of engineers.
