Fabrication drawing can be regarded as special type of detailed drawing, some of them are virtual assembly drawings, and for example when there are two or more components fixed together, it can be termed as fabrication. Basically, it consists of the entire materials which are a must to constitute one drawing. They also have certain codes and standards that are to be learnt.
Fabrication drawings are very much clearly described and these have the perfect dimensions and after following the fabrication process the geometric parts have to be analysed. It is equally acceptable to show all the manufacturing details in it.
These are mainly used in:-
1. Structural Steel
2. Sheet Metal
3. Architectural Steelwork
4. Stairs
5. Balustrading/Handrails
The drawings are similar to manufacturing drawings and are divided into two categories:-
1. Single Part Drawing:-Single part drawings are workshop drawings which show details of one part such as a single beam or an end plate. These drawings are usually presented on A4 size papers.
These drawings are supposed to show sufficient information for the material cutting.
2. Assembly drawing:-Assembly drawings are workshop drawings which show the single parts assemble such as beam with end plates and they are prepared on small sheets like A3 or A1 for assembling high complex structure with many single parts.
The fabrication shop drawings shows relevant details and at times some precise ones are also marked on the sheet. The items used in fabrication drawing are identified by numbers these number’s should reflect the difference and methods for identifying numbers on fabrication drawing include lower case letters such as a or b or c, or in numeric form like 1/2/3 or sub-units like 1A/2B/3C etc.
Cost
Fabrication drawings are usually having fixed price and they are able to quantify work easily. Structural Engineering Drawings and Architectural drawings are needed to provide fixed drawings.
Fabrication Shop Drawings
A fabrication shop drawing is a drawing or set of drawings produced by the contractor, manufacturers, fabricators or sub-contractor. Before fabrication is done the shop drawings are required for prefabricated components. These include elevators,, structural steel, pre-cast windows, cabinets, air-hanging units and millwork.
CAD with paper and pen
Making drawings with hand are excellent and also showcase the inside depth in them. We can also draw it in 2D structure to get a basic idea.
Views
Basically, one drawing involves a lot of figures and is offered explanation in different terms. Their opinions and different perceptions are all noted down along with certain locations as well. What are required without any doubt are mentioned in the well terms as follows, have a look.
• Axonometric Views
• Orthographic Projection
• Sectional Views
These also indicate clear dimensions and are understood quickly and clearly. Indicating features sizes and location and other minor details will go a long way to minimize the use of fabricator’s time. Fabrication time cannot get the exact dimensions so the dimension tolerance is needed. The most important thing in fabrication drawing is to remain consistent so that the drawings are easy to follow.
