I am new to this site & need some advise before booking a CAD course. I have used Autocad in a planning depatment of a telecomms company years ago & enjoyed it. I am now looking to take an official course to gain the qualification. Baring in mind that my background is Installations/Streetworks I need advice on which course to take & who with. Also, please can someone tell me more about 2D & 3D Cad & how important it is to have both? Thank you very much for any advise you can give me.
