I’ll never forget the first time I saw computer-graphed equations. It was in the seventies and a co-worker was displaying the results of his work. Beautiful curved lines intersected and intertwined to create a picture that deserved to be a work of art. Until that time, I had perceived computers as a way to automate business tasks and analyze data.
Despite that early introduction, it was several more years before I heard the
term computer assisted design (CAD). There were some early prototypes at that time, but the advent of personal computers and the introduction of AutoCAD software in 1982 gave a tremendous boost to the popularity of computer-assisted design. Early models were 2D and resembled hand drawings. The technology has developed over the years and now includes 3D renderings, which can be viewed from multiple perspectives. CAD is used in applications as diverse as aerospace, prosthetics and special effects for movies.
I always dreamed of owning CAD software, but AutoCAD’s price was prohibitive. I looked for software that might be an AutoCAD alternative, but found nothing comparable at that time. Times change. I’ve recently read about ZWCAD and ZW3D, ZWSOFT products that offer an AutoCAD alternative with comparable functionality at a far lower price. Lower works for me. I’m excited about the possibilities that ZWSOFT’s products provide as an AutoCAD alternative. Maybe my dreams of owning CAD software can be realized.
