Railing will not host to stair stringer

[mpukas]

I cannot get a railing to host to a stair stringer, so that the start and end posts (as balusters, with cut angles in the family), and balusters sit on top of the stringer and change/adapt to to changes to the angle of the stair run as it's being developed. The post as balusters and balusters will only host to an imaginary line drawn to the leading edge of the tread nosing. I've tried every possible trouble shoot I can think of... and I'm stumped... when I create a new stair from scratch, I set the railing to stringer, not tread. In the railing family, the base is set to host. But there's way I can discern what the host is - the tread or stringer? I can't change the railing host to specifically select the stringer. 

With the base set to host, the bottom edge of the balusters is not cut at the angle of the stairs, it's square, as if it's sitting on the tread. 

In the screen shot, I'm showing the stringer as a C-Shape, and you can see that the posts/balusters extend below the top flange to the tread line. 

Thoughts, please? TIA

Checked the offset?  

....ah, I read a little further. This has been posted about before. Offset is of no help.  

[mpukas]

yes, have played with offset from path under constraints, as well as base offset in type properties. No change, railing does not host to stringer

Post the file. Let's have a try.  

...btw, is your railing using balusters per treads on stairs?

Share the baluster/post family here.

balusters per tread not selected

See revised model.  Control railing Offset as a whole by Offset from Path parameter.

@ToanDN Yes, that solves my problem. I knew there had to be something I was overlooking. Thank you!

I have a stair with a mono stringer in the middle. Is there a way to stop the balusters, in between the start and end, at the bottom of the treads? I have the start and end down but the in between ones range different depending where they hit the tread.
