There are more than 30 varieties of CAD software available in the market, which are sourced from different software developers. Apart from these, customers also have the option of downloading freeware and shareware available easily on the Internet. Customers who want to buy CAD software should conduct a comparative study analysis to select the most suitable software among available options.
CAD software can be compared using different product criterion such as cost of the software, developer’s profile, after sales technical support and future upgrades. This can be done by using an excel spreadsheet or other software. Product analysis software is also available in the form of freeware, which can be used to compare and select the most cost effective CAD software.
CAD software systems are also compared based on features such as two dimensional (2D) or three dimensional (3D), CAD or CAD+CAM, operating system compatibility ( windows, UNIX, Solaris, and SunOS), microprocessor requirements ( Pentium, Celeron), hard disk space & RAM memory requirements, and supported formats(IGES, DXF, STL, SLA, Gerber, HPGL, CadKey & APT, CATIA CL, Excellon, Gerber).
Customer reviews can also be used to compare different CAD software. Reviews are written by CAD software users who describe their experiences about different brands manufactured by different software development companies. A number of websites are completely dedicated to provide information about CAD software reviews, which can be used to gather information on the benefits and drawbacks of different software programs.
After comparing, different brands of CAD software are rated on a scale of one to five, which is commonly known as star ratings. A rating of four and above indicates that the software is good and can be purchased. Software systems that are rated below three usually do not have advanced features and may have inherent defects. Customers who do not have in-depth knowledge about software systems should opt for CAD software that is rated in the range of four to five.
