I have 1 constraint that i cannot find so that the sketch is fully constrained. What have i missed?

The part is 2013

Thanks

There is a hidden segment in the following spot:

As a tip: you can use the automatic dimension tool to find these sometimes.

thanks niels..i did try the dimension tool but it did not pick up the missing constraint. i cannot seem to get it to fully constrain

I have it...deleted the short line and used the coincident constraint to connect the 2 points.Thanks

In order to get it fully constrained, you could use a horizontal constrain to the intersection of the construction lines.

I'm not sure why the extra segment got created though, so it might be better to see if you can reconstruct those lines as a single element.

Make sure you don't end up with tangency problems, i wasn't able to apply a tangent constrain after i did the same.

Yes i did see that.I used your method after.Thanks for help
