False unconstrained result

[etfrench]

Sketch.ShowUnderConstrained is showing two points as being under constrained. 

But they both have endpoints coincident to a Fixed spline:

Hi,

Isn't a Spline a calculated entity? This would mean that your y position is fixed by the Dimension

but your x position is calculated and technically floats. Wouldn't this be unconstrained? That might

be the reason. The last time I had issues with Splines like this was importing an airfoil. The way I

fixed it was by creating a new Sketch and Projecting the curve of the airfoil. This locked it down

because it was in a fixed position. I then made other features co-incident or whatever to the Projected

curve and not the original spline.

I once got caught by a Hexagon that I thought was constrained. I Dimensioned the x,y for the centre

and the length of the sides. It still rotated around that centre. I couldn't see it until I grabbed a side

and it moved. In that case everything was "black" too but it wasn't constrained.

Cheers

this looks like a sketch solver bug to me.  I was easily able to reproduce it.
