I've inherited a stair that needs to have handrails remodeled. What I'm finding is that there is a problem with the height of the handrail generated at the top of the stair. I'm hoping someone can take a look and see what is causing this incorrect result:

Typically, this is controlled by your railing sketch.  Make sure your sketch line intersection is at the last riser if both landing and stair handrail height is the same.   If that junction is over the stairs, the landing railing will be lower.

I thought that too. I tested creating new ones as defaults and still the same result. I should not have to tweak the sketch incrementally to get the correct result. This should be a default of the stair if everything is set up correctly. So I'm trying to figure out where the error in the components parts are that is yielding the incorrect result.

My expectation is that the top rail family should create the correct condition at the top of the stair w desired heights input. Otherwise it appears that this feature is useless?

Not necessarily. Please see the pictures, I hope they clear things up a little.

 

The condition with ‘end with riser’ unchecked - fig 1.

If you activate ‘plus tread depth’ option, its necessary to shorten the rail at the top by one tread (fig 2).

The condition with ‘end with riser’ checked, is shown on fig 3.

Ah ha! That confirms Mr.'Hub's point about the sketch path. Troublesome that there's not a conditional argument made in the railing system that would account for that automatically. Thanks for pointing out that trick! I appreciate it!
