I take it you are using ISO standard?
can you get away with showing a foreshortened radius?
You can right mouse klick on the dimension line and select hide dimension line.
I had the same problem a while ago.
I enlarged the boundary of the detail in the parent view to a point where the whole item was within it. This enlarged the detail itself. Then in the detail place your dim. Then reduce the size of the boundary to fit.
rmb on the extension line you want to hide and hide it
rmb on the dim line to hide it it reqd
Only works with ANSI dim style all others seem to keep the dim line between the leaders.

If its a circular edge, put in a radius dim, RMB and select Show as Diameter.
