Why design with CAD software?

CAD software has automated the drafting process since we first traded in our drafting tables, T-squares, set-squares, mechanical pencils, erases, and sore backs for a computer, keyboard and mouse.

Computer Aided Design (CAD) software is a more time and cost effective way of producing detail house plans for construction. Operating CAD sofware can be relative simply. Also, you can learn CAD on your spear time and become very compotent operator too.

CAD software are used in a range of industries and professions.

Manual drafting versus CAD software

CAD design professional primarily used Manual drafting for complex project, because of the time it took to produce and revise these drawings.

Computer aided design drafting applications were introduced for commercial drafting in the 1960's and 1970's. During this period CAD programsmwas limited to the production of orthographic or 2D drawings just as manual drafting only much faster.

In the 1980's CAD took on a new dimension known as 3D. This would lead to the creation of precision 3D software in the early 1990's.

Potency of CAD softwares

CAD software versus Parametric modeling

CAD represent the traditional drafting methodology for generating blueprints through the use of vector file based line to represent objects.

Parametric allow us a CAD designer to virtual create an object and dynamically orient that object in real time.

BIM represent a new era for design software and possibly a new method of managing construction process and reduce cost through virtual information modeling.

This evolution of computer aided design has made many tools available for professional and amateur users of drafting software.

1. Better imagery2. Easy retrieval of embedded information3. Coordination of construction documents4. linking of vital vendor information to drawing file5. Reduce delivery time CAD programs can now incorporate industries product and standards into drawing process which further enhancing the functionality and usefulness with the introduction of Building Information Modeling (BIM).

As a design professional or amateur, BIM also allows the luxury of modifying element in any view which automatically updates all other affected view.

BIM also indicate if their is conflict between different discipline example Mechanical and Structural, allowing these issues to be resolved in the design phase if the project.
