My Review - based on Power supply design (schematic + PCB) above
Autodesk 123D seems quite neat. Large collection of components, simulation capability of arduino programs and virtual breadboarding with oscilloscopes and multimeters is really nice.
Though my review on the schematic and pcb design tool is that it needs more polishing to be effective for complex designs.
I found Autodesk 123D Schematic and PCB design tool relatively harder to use than other softwares like Designspark pcb, kicad, Eagle among others. It lacks many design features that ease design work(I suppose the RND team are working on improving this). The hardest part was Routing the copper traces, which needed to be done manually with no assistance tool such as interactive autorouter or provision of any external routing software
I recommend Kicad for this particular project, which is much more suitable for this task
