Invalid solution found

Hello

On some pieces, in a sketch, SW 2013 gives me "invalid solution found" with the lines in red or yellow depending on the case.

Until now I was redoing my play differently until I no longer had this message but it lasted, it lasted, it lasted...

And then I decided to ignore the message and surprise, he does the extrusion or the removal anyway, leaving me the function with a yellow triangle.

What should we do in this case, where is the error because there must be one?

Hello

In general, and in this specific case, it comes from a sketch that is overstressed. So redoing the sketch that is used for the extrusion of the tabs solves the problem.

Without necessarily redoing everything, first remove all the relationships (coincidence, collinearity), then replace them one by one.
Sometimes, changing the type of relationship (replacing a collinearity with a coincidence, a coincidence with an equality) is enough to solve the problem, to avoid the effects of a cascade like segment3 equals segment 2, itself equals segment 1 to be replaced by segments 2 and 3 equal to segment1.

Hello 

A quick solution is to delete these two lines (rather splines), then redo the offset, 

The cause, I can't determine, the sketch is so under stress, anyway the offset with end closure works, it's what you did after that's wrong, I imagine that you adjusted lines and assigned verticality constraints :S

Thank you for your contributions.

I ended up getting there by doing what @stefbeno advises, which is to delete all relationships, a bit long but it works.
