workflow: bodies inside parts, set in position, scketches with relations, shape binder green wide using (great!).
lessons: I've been working with 3d cads since 1992, at the time in Fiat-Iveco...there is little bit of personal story and background...
what issues did you encounter and how did you solve them:
mainly the middle point datum reference, it has to be implemented in my opinion. If not you can work it around by sketches or datum-distances, not simple and not a natural way of designing in my opinion.
techdraft dxf exporting little mess: in my opinion it has to be changed by exporting hiddens on one layer, visible on another layer, axes one another layer too and so on.
About this last: normally 3d cad are good for 3d modelling, but little woody for the 2d draftman's job. Don't change the nature of things. Better, in my opinion, is doing an efficient export by dxf and finishing views and sections inside a 2d libre and so on. A good dxf export is necessary also for those who want to work inside Freecad also for 2d. If not, It's impossible an industrial quick drawing exchange between 2d cads.
In a close future, I'll be posting here a nostalgia-motor glider model airplane did at home on winter sunday afternoons. This, I can post the construction and the maiden flight video too. Coming soon.
Thank You very much indeed!
You, faber libertatis!
