Summary	0003389: Using Draft-PathArray on a Sketcher Arc with Align=True results in "Value out of range"
Description	When using the Draft PathArray to align on object on a Sketch Arc the Object is aligned correctly initially but when the Arc Radius is changed or the Arc Angle is changed a Value out of Range error is produced. However the error does not happen for every resize. I have reported this on Forum at: https://forum.freecadweb.org/viewtopic.php?f=10&t=27428 I made a screen cap at: https://youtu.be/MVLm1e3z5vI
Steps To Reproduce	1.) In Part Design WB create an Additive Cube. ( or any object ) 2.) Create a second body with a Sketch and an Arc. 3.) Switch to Draft WB 4.) Select Cube and Arc, click PathArray Tool 5.) In resulting array change the Align property to true 6.) edit the arc sketch and increase/decrease it's size until you get error It seems larger changes produce the error more reliably. It also seems like the closer to the object the path is the less likely to get an error.

Kunda1 2018-11-19 10:32 administrator ~0012219	@yorik what release should this be assigned to ?

wandererfan 2018-12-08 02:06 manager ~0012244	I can't reproduce this on v0.18. Also the test file is not fully constrained and has redundant constraints. The only error in v0.18 is "link go out of allowed scope". PathArrayAlignedBugConstrained.fcstd (14,092 bytes)

wandererfan 2018-12-08 18:05 manager ~0012245	marking this one "Resolved"

yorik 2018-12-28 02:18 administrator ~0012343	I also did some testing and cannot reproduce the problem, I suppose it doesn't apply anymore...
