Hi!
After making several improvements to Part workbench, in particular the 2D offset feature, I decided to re-do an old project which I call Ellibox.
It's just a box with a cap that is slightly elliptical, so turning a cap makes it lock a little bit. Too easy, right?
The original project involved Sweep and Connect (both box part and cap part are the same in construction). The resulting project was quite messy.
Now that Part Offset2D is available, I can make the project much simpler, by applying a bunch of offset operations to the base ellipse, and a bunch of extrude operations. Easy, right?
Who'da thought this project will put out great resistance to get the result!
Bugs discovered:
Bug in Part Offset (3d and 2d): expression units
Bug in Part Offset 2D filling
2D offset creates curves of unsupported type
Extrude Offset Ellipse is invalid geometry
Part Offset2D, Draft Clone and Extrude direction weirdness
Phew!
