In 2016 cad++ I used to be able to construct a pierce point from an auto circle right on the tangency of the circle, in 2018 I noticed when I try this it says math failed? So all I want to do is create a point on the tangency of the outside of my circle, without having to use a generic and type in CIR1.X, CIR1.Y,.CIR1.Z as an example any advice?

Here, if you want to constuct F1, the tangent should be perp to the radius (it's mathematically always the case !), so construct a line perp to the line and through the circle center should help creating the point.
If the distance between the line and the circle center is shorter than the circle radius, then, there's no solution.
You could apply the little arc method, then construct a feature set with circle hits and intersect points, and create a circle from them.
