Architectural tools play an important part in the solving design issues. The best way to represent a designer's imagination in a concrete reality is by using drawing techniques. With changes occurring in the field of technology and design the use of drawing tools has also evolved and improved.   Although   digital tools   replaced conventional drawing tools that were used in the past, the influx of computer technology in architectural design has had a profound influence on how buildings are planned and constructed. The widespread use of digital technology (IT) transformations at this stage introduced technologies that encourage the development in architectural designs and manufacturing techniques for reasons other than necessity, and their impact on architecture is still widely undefined. Many new software applications for digital models with Building and Modeling Knowledge have launched in recent years been used for model developing and 2D drawings as well. This study aims to analyses the characteristics and nature of design process and how it is evolved from beginning through organic approach till now with the advent of software packages, by doing so it will highlight the comparison of conventional and modern tools and the impact of software tools on architects and design, the advantages of utilizing software tools in the field of architecture.
