Sketch distance cannot resolve

gauthier_östervall

I am trying to use the distance tool to constraint a sketch.

Here is the blue line in my sketch, I am focusing on the top one. Manually movable:



Fixing the length with the distance tool:



When I try to change the length by entering a distance, the sketch becomes unresolved.



I don't understand why I can manually move the line to approximately where I want it, but not assign a length with the distance tool.

Here is the project.

What is going on?

EDIT: interestingly, it works if I remove the half circle. I don't understand why that half circle is blue to begin with, it's not movable after fixing the distance (in the picture with 8.91 above).

Certainly some weird behavior. I got it working by making the other unconstrained geometry constrained (just clicking the construction line and the circle to lock it down, and adding a dimension to the other line).
