DC StairCaseBuilder

Howard, Thank you this is great. I wish it was in inches.
I could use it all the time. Of course, I could break down and learn how to use it in metric. 
Thanks again for your generosity.

Thank you.
-
Yes, its really a great component. Thanks for sharing!

From a distance, certainly looks nice, but codes in my vicinity, and throughout most of the US, require more horizontals: 4" inch max clear is common. Tough luck for the yanks.

Howard,
That is a great tool, how can I get a copy ?

In the UK under "Part K" it's even slightly smaller - a 100mm diameter ball shouldn't pass through any gap in a stairs risers or associated railings/balustrades [there is an exception for the potentially non-compliant triangular gap between the riser/tread and a raking balustrade bottom]. This rule applies to any 'domestic' stair or building where you might reasonably expect children aged 5 or under - i.e. schools and the like. These days this is effectively most public buildings and even offices too - indeed, there was a tragic accident at a national TV station's offices a few years ago when a toddler fell several floors through a more open balustrade around an atrium, and was killed - he was there with his mother on a 'take-your children-to-work' day. A building operator is responsible for the Health and Safety of staff and visitors, so even if the Regs allow it many want 'safe' designs. Now only stairs in plant-rooms and the like can be the more 'gappy' type.
This '100mm ball rule' is actually determined from a toddler/baby's head size - whilst having these reduced gaps stops older kids falling through, the concern is that 'crawling' youngsters might squeeze through a small gap 'backwards', then fall BUT still get their head stuck in the gap if it's bigger than 100mm and then they could break their neck or strangle themselves - BUT they can't get their body through the 100mm gap in the first place, and so are 'safe'.
On aside note: I have also done work on maximum security prisons - in those the maximum gap is 125mm [was 5"] between rigid bars etc, this is determined as a gap a normal adult can't squeeze through - although in one jail there was a small skinny guy who would amuse himself by winding up the guards, he'd squeeze his whole body through the bars, but then get stuck because his head wouldn't pass through - then he was completely uncooperative about getting back through to the side where his head was [sawing off his head seemed the attractive option, but it's not allowed under some daft human-rights rule or other
]. Also no 'Shawshank Redemption' escapes because prison drains passing out of the secure compound can't be more than 300mm/12" internal diameter in the UK !
Back to the stairs... open-riser stairs of any type are also disallowed in public buildings under the Disability-Discrimination-Act[DDA]/BS8300 and Part M - 'Accessibility Regs' - if people with calipers on there legs might get then caught !
Where open-risers are allowed their gaps can be limited to <100mm by adding a single thin rod across them, or more commonly making the tread thicker at the riser location, or making the back of the tread with an upstand of ~25/50mm so that the gap is reduced AND you also have something to stop the tread finish against neatly.
Also often forgotten is in domestic/<5yrs buildings the parts of a balustrade etc are not allowed to be horizontal [rails etc], or even have 'holes', that could an be climbable by small children.
You talk about restrictions - "natural selection" has stopped here...

Thank you, Howard. At heart, of course, I'm just another spoiled child, wanting it all on my plate, served up, with savory sauce.
Thank you for delivering.

Brooke,
Some Top Tips for you ...
Use StairCaseBuilder to design the bulk of the Staircase, then ...
Finish off handrailing as shown - ProfileBuilder or PipeAlongPath Ruby Scripts help in this task.
...........
See attached file to give you some ideas.
StairCaseBuilder incorporates Horizontal (Handrail) and Vertical (Stanchion) Guidelines.
These are GUIDELINES that can be further enhanced or detailed to complete your staircase as required.
..........
Handrailing GUIDELINES (simple lines) are used in this DC (as opposed to more detailed handrailing) as the possibilities / combinations for more detailed handrailing are infinite eg- Position and Spacing of Stanchions.
- No and position of Horizontals / Verticals
- Handrailing / Stanchion Cross Sections, Which to choose ? eg Circular, Oval, Semi-Circular, Square, Rectangular or a more detailed / fancy section ?
..........

Thank you! You've made me appreciate dynamic components and glad I chose to get SU Pro. This is a real time saver!
-
I hope my last post doesn't give the impression that you can't use this Dynamic Component with SU free. You can, of course. I mean it's inspired me to learn more about how to create them, which you can only do in SU Pro.

In case you haven't seen it yet - you may also like to try this DC for creating doors (another time saver). I created it because I found that I was forever having to model doors from scratch - this DC is also animated (use magic finger icon on DC toolbar):
