Difficulty with coinciding a tangent line

alex_hepp

My shape will not close because the coinciding constraint is not on but when i set that constraint then it says that the shape is over defined and the entire sketch turns red. What am i doing wrong and how can i solve this problem?

I don't think that anyone can quess whats wrong unless you share a link.

@alex_hepp , Make your sketch close by adding coinciding constraint. Now your sketch became red because your sketch containing extra dimension due to that it became over constraint. For making fully constrain you have to remove unwanted dimension from sketch by showing "constraint option". It will highlight responsible failure constraint in red color. You have to delete one of them after that sketch will become fully constrain.
