Summary	0004277: Result of Part:Cut operation is distorted.
Description	The cut operation of two lofts make unexpected result. The resulting object doesn't keeps outside shape of original sub-components. Lofts are created from multiple sketches. It looks that some points (2 in my case) of the original outside object are replaced by points from inside (subtracted) space.
Steps To Reproduce	1. Start the FreeCAD 2. Open attached file (Jak9-WingTip.fcstd) 3. Select the Part workbench 4. Make a Cut of two shapes: (WingEndOuter - WingEndInner) 5. Check resulting object on the thinnest (higher Y coord) side for distortion

openBrain 2020-03-03 15:27 developer ~0014202	@david254 : sorry but this is just EBKAC. ;) In the properties of the 'Cut' (Property editor -> View tab), just adjust deflection and deviation to something more appropriate to the scale you're working on (eg. Angular deflection = 1 / Deviation = 0.05). Then recompute & everything is fine. This is typically case why our guidelines require that you first open a topic on our forum so community can confirm it's a bug before you open a ticket. ;)
