Designing a parametric wing in Onshape - going for maximum flexibility!
My goal is always to create as highly flexible/robust parametric models as possible. Here is an example! I am starting a project (not timeline, it's a personal interest thing a bit like my violin I published earlier) for an RC airplane (aeroplane!) and the wing is a great place to start. There are some really nice capabilities in Onshape that allow for super-parametric designs, which are especially useful in the early stages.
For those relatively new to Onshape this might be a good one to see how I use sketches (and sketch colors!), intersection curves, mate connectors, variables, feature patterns, frames, directed edit, surface features (e.g. loft), folders, and a custom features to help me out.
