Odd sketch under constrained BUG.

[HughesTooling]

I have the sketch below that uses some projected geometry and should be fully constrained. The odd thing is if I delete the perpendicular constraint it then becomes fully constrained, all the perpendicular constraints were automatically create while drawing. To me it should be under constrained after deleting the perpendicular constraint but I think the 12.00mm and 5.5mm diameter dimensions end up constraining the centre construction line as parallel. I can't easily share the actual design but I've exported the component and Fixed what was the Projected geometry and the export shows the same behaviour.

Edit Testing a bit more I've found if I delete the 5.5mm dimension then add back between the centre line and just the end  point of the line it will show fully constrained as well.

Hi @HughesTooling - I took a look at this, and I'm not 100% sure I understand the problem.  The version of the sketch here does not have a vertical constraint on that construction line.  If I try to add one, I get an overconstrained error.  However, there is a legitimate bug here - replacing the diameter dimension (5.5) with a regular dimension (2.75) to the centerline does make this sketch fully constrained.  That is definitely a bug.  I'll log that one

[edit] the bug is:  FUS-67416

@jeff_strater  I didn't mention a vertical constraint, I said if you delete the perpendicular constraint on the construction line the sketch shows as fully constrained. What seems a odd is if you delete the perpendicular constraint, is the centre line direction is only being constrained by the diameter dimensions. I guess the dimensions are also working like a parallel constraint so the original constraint is actually over constrained?

It does seemed to be linked to the 5.5 dimension, if you look at my second picture I made the diameter dimension between the centre line and the endpoint of the line rather than selecting the 2 lines.

sorry, my mistake - it was late, I was tired, and was probably watching TV at the same time, so was only half-focusing...  It happens.  Anyway, there is definitely a bug with that diameter dimension.  Should be fully constrained with the diameter dim.
