When you are just making stuff for yourself it’s fine to just sketch things out on a pad and make them. However, if you are working with others it is good to have proper drawings that you can share and discuss. I have also used a 3d Graphics program to visualise some of my projects.
This year I’m looking at getting back in practice with using a CAD system so I can draw up some of my projects. I did have several weeks training with Dowty back in the 1990s on manual drafting and a little time was spent with their DOS based Autocad system but things have changed a bit since then. So I asked the CAD Expert Paul Tracey what his recomendations were.
