Well, Heck, here I am again, quirky as ever. This may be a FreeCAD quirk, or prob'ly not, but I swear I have re-checked the dimensions many times, and they all add up to a vertical sidewall, yet it appears slanted. Here's the Main Pad of the Real Bowl. (Body001 is temporary, trying it on for size to then re-create it in a separate Document. It's just a Pad Disc, same Diameter as the Core Pad, with lips on its rim.)
You can see on the Right End front view, it is vertical:
, whereas the Left End is slightly atilt:
. This tiltedness is more pronounced when a the first Groove is visible:
, and the Sketch for this Groove does not line up, even though its parts add up to the same diameter as the Core Pad and Body001:
All the Lines in the Groove Sketch are constrained to vertical, the outside edge of the Sketch is constrained Vertical from the Diameter of the Core Pad, and the datum Constraints all add up to the diameter of the core Pad and Body001, so is this tilted sidewall due to crappy hardware, or a FreeCAD quirk, or maybe those Tangency Constraints are stretching the curves a little, or maybe there's some flaw in my strategy or design, which is the most likely scenario, but if it's a bad Sketch, wouldn't the sidewall be tilted all around, instead of just where the Sketch is?
Will you please share your thoughts on this? Thamks.

Also some interesting co-planiarity things came to light with the Pipe and the Pipe Pre-Pocket. Basically, when I pocket out a pathway the same Outer Diameter as the Pipe, I get an error about the Pipe not being a solid, since it's like half a micron away from the inside of the pathway, so if I make the Pipe Pathway Pocket the same diameter as the Inside of the Pipe, the Pipe then intersects the Bowl and FreeCAD finds it solid. Best Practice here would be to make the Pipe Pathway Pocket smaller than the Pipe Outside Diameter, but larger than the Pipe Inside Diameter, to avoid coplanarilaty (cylinder-style) on the Inside and Outside of the Pipe.
