National CAD Standard
In a world where globalization is invading and distinction is becoming therule,We feel the urge to pass some of the knowledge we acquired through our years of humble experience. We will put between your hands some tools that will allow you in thenearfuture to be at the level of the challenges that any ambitious person will face, if planning for a successful career.
National CAD Standard
In this course, we will introduceinternationalstandards.likeany language, architectural and engineering drawings have their rules. Many systems and codes can beapplied,Maybe the most common of all is the NCS or “National Cad Standard” or “Standard”.
National CAD Standard
This “Standard” will allow you and the majority of the world to understand each other’s through this language which is the “drawings” that each architect will use to expresshimself.
National CAD Standard
We will start with a brief about the purpose and reasons for the use of NCS in each different phase of a project, then we will define execution phases, then we will discuss the layering system, sheet numbering system, drafting conventions, tags and symbols, hatch, patterns, etc…All that will be in the objective of a better understanding of the project cycle and the specific phase of your projects.
National CAD Standard
NCS is known as the “National Cad Standards” for architecture, engineering and construction; it is called also “the standard”.NCS intent during the design phase is to speed the transfer of information between owner, designer, consultants, contractors and subcontractors.During construction, NCS intent is to reduce time in finding and referencing information between owner, designer, consultants, products suppliers and manufacturers.
National CAD Standard
NCSScope of work:Data Organization: Organize cad files: it addresses issues such as layer name, discipline designators, line weights, pen assignments and the graphic organization of the construction drawing sheets.Dataexchange: Helps to guarantee the future utility of today’s Cad data files.
