Seems that Solid Edge does not allow a driving dimension with an intersection point involved.
Meanwhile, I could infer that with a perpendicular relation for the vertical line on the left and an angular dimension for the inclined line on the right, besides radius dimensions for the two arcs ensure that the dimension applied to just the end-points, give a consistent intersection point i.e. at the same location. So this would effectively be same as dimesioning to an intersection, unless you have some other design intent which is not obvious here.
Does that meet your requirement ?
....but on searching with keywords it does not locate the old thread. Is this working for you?
Seems to find topics for me buddy....it depends on where you are in the forum, as the "Search Granularity" filters to your locale by default,.....but you can change it to search within [amongst others] "Board", to cover all topics, in all groups. [well, all that a user has access to]

Thanks @SeanCresswell its working for me too. I earlier thought of searching it closer to where it can be expected to be found quicker - the forum section. The search strangely seems to be working smoother after going a couple levels up.
