Locating Sketch Unconstraints

[jeph00]

Hello everyone.

As I understand it, when there is a lock next to the sketch symbol and all the sketch lines are black it means that the drawing is fully constrained, like in the screenshot attached.

In the part I have attached, it shows that it is not fully constrained, even though all my lines are black. What are ways I can determine why my sketch is unconstrained?

Yes all black lines is a requirement along with no white points.  You have one of these.

You are victim of the coincident points are hidden trap.

I see no benefit in this model of projecting a plane, even though it has no bearing on the problem.  

If you are the author of the sketch, you should be able to find it, 

Might help....

Enter this in the Text Command Window:

• Sketch.ShowUnderconstrained

File -> View -> Show Text Commands

...did you find it?

Two lines ending here where there should be only one construction line.

Yes @TheCADWhisperer I got it. Used the Text Command like @etfrench suggested. I did not even know that was possible. Thank you all for your help @g-andresen @davebYYPCU 🙂
