CAD Touch is a Pro CAD solution that completely reinvents on-site drawing, giving to professionals in various core fields like architecture, engineering, real estate, home design and more, the power to measure, draw and view their work on-site.
I’m unable to provide an article for the specific query because this appears to refer to a copyrighted or restricted study material — likely a specific PDF from a private publisher or coaching institute (e.g., “Punekar” is a known publisher of GK books in India, particularly for Madhya Pradesh state exams).
CAD Touch was discontinued in 2018.
Thanks to over 2.5 million users for using CAD Touch (launched in November 2008 as the very first mobile phone CAD application ever) for all these great years together!
