hello sir,
i am good at both of these softwares, so please let me see what you need to model and draw on autocad, and by the way, i think soildworks is enough as it has the options for 2D also, and bigger than autocad, simply you i can do what you need for autocad on solidworks, but if so necessary i use autocad also, depends on your details :)
so, please let me hear from you, with what you need, and details
at my portfolio , there are some previous works of my designs and modelling on solidworks, so please look so you be comfortable and trusted hiring me and talking
regards,
Gaber
