This is a section cut through the stair that my tutorial had me build. I've done everything that the tutorial wanted me to do, but I wasn't happy with the guardrail. I wanted to make the rail look more code-compliant...the bottom rail left too big spaces between the rail and the treads.
So I figured out how to move it down. (I haven't respaced the others yet, just to be illustrative.)
But then I noticed the nosing strangeness at the arrow above. How to fix? And the baluster seemed to be hovering over clear space, in front of the nosing, so I tried stretching it back and got this image.
Which is still Not Good Enough.
I suspect I may be jumping ahead of myself in expectations, and that I should just keep trucking through the tutorials, and I'll learn a finer degree of control farther along. I hope so. Or perhaps this sort of representation problem gets fixed by "hand" in CD preparation? I hope not - this sort of thing could be annoyingly difficult to remember to detail - what if I hadn't looked at this particular place, from this particular angle?
Perhaps that's a new schedule item, using BIM - "Pretend to use your building. Walk through slowly, in real time, as if you were a student on a special tour of an architectural Wonder. Be critical, and take notes."
