However, parametric modeling is not without problems. Other modeling technologies have tried to gain market acceptance, but parametric modeling has proven to be more reliable, more robust and more powerful, enabling engineers and designers to create new products in record time. This is a huge time-saver and helps to reduce design errors. Changing dimension values – or adding, editing, reordering or deleting features – automatically updates a part’s geometry and all associated downstream deliverables, such as assemblies and drawings. The beauty of feature-based parametric modeling is that engineers can create solid models with an ordered list of understandable modeling features (sketch, extrude, fillet, shell, etc.). I took on a lot of work for Mars (Electronics) and there was growing pressure from them and other customers to buy a CAD system.For over 30 years, feature-based parametric modeling has been the gold standard for creating complex parts and assemblies and is used in production every day by hundreds of thousands of companies worldwide. “I literally went back to the drawing board and offered mechanical design services using pen and paper. Soon Alan realised there was more work and more money in product design. The dream of being a graphic designer didn’t last long though.
A few weeks later in July 1989, after re-mortgaging, I handed in my notice and Visitech Design was born.” “Typically Mars said, ‘we don’t want to lose you, so we can’t give you the redundancy package’. But like any business venture, it is never plain sailing. Alan put together a business plan and set up a Barclays business account and even started trading.
With a company name Visitech, a play on visual and technical design. The package wasn’t particularly generous but more than enough to start a Graphic Design business… so, I set the wheels in motion.” Mars told me what they would give me if it went through, so I was determined to go for it. I still thought I wanted a career in Graphic Design, so I enquired about the redundancy package. “All throughout my employment I had been doing a little work on the side with small design jobs but also with a lot of graphic design projects.
