Objective

As discussed yesterday, let’s first define our objective before starting our voyage through AutoCAD. It is obvious that what we do with AutoCAD is drawing / drafting / digitizing / modeling. There should not be any disagreement about it. But what could be the possible collective term for all types of this data and what would be the purpose of creating those? In the next paragraph we will discuss the same.

Production Information

• Production information can be defined as –
  ‘the information prepared by designers and facilitated by the CAD TEAM, which is passed to a construction team to enable a project to be formulated’
• Evidence shows improvements in quality of production information:

1. Reduces the incidence of execution quality problems, and
2. Lead to significant savings in the cost of execution work

• In simple words Production Information is a ‘Working Drawing’
  
  All right! Now we understood that what we are going to document is ‘Product Information’ in form of various drawings and graphics. This product could be a piece of furniture, a mechanical assembly, a building or an infrastructural element like road, bridge or a flyover. No matter what your product is, the basics of drawing apply to all of them all the same.
  
  What do you mean by Drawing?
• An idea represented in a sketch form
• Communicating visual ideas
• Expression of thought in a bare form
• Use of colors and textures to differentiate elements
• Outflow of concepts
  
  Okay, now we have an idea of what a drawing literally means. But it still doesn’t say anything about drafting. Is drawing and drafting one and the same? And if not, what is that sets both apart?
  
  What is the significance of Drafting?
  
  Difference between Drawing & Drafting
• Drafting is a sketch presented in a structured form
• Drafting gives Technical Dimension to the Visual
• Drafting is a Process of converting thought to reality
• Drafting incorporates Symbols and Annotations to make the idea UNIVERSAL
• Drafting facilitates Practical Birth of a concept to take Real FORM
  

Today we learnt three basic concepts –
1. Production Information
2. Drawings
3. Difference between Drawing and Drafting

Tomorrow we will try to understand the concept of CADD, stay tuned…!
