Re: Design question - Waterproof
If it won't be waterproof in its first version, has any thought been given at this early stage that will make waterproofing easier to implement at a later date? For example, concentric grooves or flanges could be added to the moulded parts for version 1.0, so that labyrinth seals can be more easily added for version 1.5.
Whilst waterproofing the design would add cost - especially the testing, if it is to be sold as waterproof - this decision does seem to limit the market considerably. [Anecdotal, I know: In my local pub (some distance from the coast) there are a couple of paragliding enthusiasts, a few motorcrossers, a couple of dozen mountain-bikers and maybe a dozen surfers. ]
I'd be interested to read of your experience of learning to use Solidworks, too, with respect to more common software: What did you make of the UI, for example, or did you find quite straight forward after you got the hang of the conventions (sketches > bodies > parts > assemblies, the feature tree etc)? Did you just play with it, or did you follow tutorials on YouTube and look at user forums?
Best of luck with this project.
