There are over 30 types of CAD software on the market that come from different software developers. In addition, customers have the ability to easily access freeware and shareware on the Internet. Customers who want to buy CAD software should do a comparative test analysis to find the most appropriate software from the available options.
CAD software is comparable to different product criteria, such as software costs, developer profile, post-sales technical support, and future updates. This can be done with an excel spreadsheet or other software. The product analysis software is also available in 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 2D or 3D, CAD or CAD + CAM, OS compatibility (Windows, UNIX, Solaris, and SunOS), microprocessor requirements ( Pentium, Celeron), hard disk space and 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. Opinions are written by CAD software users describing their experiences of various brands produced by various software companies. Many Web sites are fully committed to providing information about reviewing CAD software to help you gather information about the benefits and disadvantages of different software programs.
After comparison, different brands of CAD software are graded on a scale of 1-5. The four and higher ratings indicate that the software is good and can be purchased. The rating systems below the three do not usually have advanced features and may have errors. Users who do not have a thorough knowledge of software systems should choose the CAD software, which is in four to five ranges.
