Steps interval

[Anonymous]

Can someone explain how can I get wished interval of steps of a stair? Whatever value I enter the joint recalculates steps interval to place them equally along the stair. For example, I want steps to be placed with the interval of 200mm (item 1). I enter 200 but the joint calculates and sets steps with interval 263 so the steps placed all along the stair with the same interval.

The only way I can get what I want is when the stair has angle of 45deg and the length=height. If angle is different - it`s impossible to set my interval.

What I do wrong?

Hi,

in my experience its all about the start and the end height of your system. If u are not used to the AS Stairs generator try to draw the stairs with some polylines. U will now see where the start and the end of your system should be.

Draw your System and keep the GA drawings close and u should be fine 🙂

What is the length and height?

Exactly what it says, length and height of a stringer. Right what you see on your printscreen.

Now try to get step interval equal to 200 (Step-General tab) for example

no, not going, I need rise=200 (sorry I mistakenly called it interval)

If your height is 3000 and you want a 200 rise that will be 14 rises. if the length is 4400 the going will be 293.33.

What height and length are you after if different?

I suppose you could do what you want but you would have to workout your start and end points to allow for the difference.

In the UK Building Regulations require you to have equal rises and goings on a single flight of stairs so I would NEVER make up the difference on the first or last rise.
