Hi,

Creating a stair using AC27, and I notice that the stair width is 1cm different at the top of the stairs than at the bottom, what could be causing this???

thanks

Can't get any more simple than that.

What does the flight width in the stair settings say it is?

And I assumes you have placed this stair by defining the length of the base line (reference line)?

You haven't edited or stretched it in any way?

 

Is it a rounding issue with the dimensions.

Can you set your dimensions to show more decimal places as a check?

Different in the same view?  Or different in views that might have different dimension settings ?

Hi Steve, on plan view I have my stairs placed. And when I measure the width of the stairs at the bottom and the width of the stairs at the top. There is a 1 cm difference. This also means that the long edges of the stairs is not parallel.

Just one more reason why I have so little to no use for the Stair Tool.  Things like that can go unnoticed for a while and cause all kinds of problems.  At least you found it.  Good luck with it 🙂

Can you show an image of the stair in plan?

Having dimensions fall on half your dim accuracy is sooo annoying...

Thanks Barry, you were right, I had accidently stretched it in the cornerby a tiny fraction and had not noticed.

I did not know this was even possible.

There is the stair baseline (reference line) that controls the path of the stair.

Usually when you select a stair you see this single baseline.

 

But if you select the stair by the opposite side to the baseline, you will see 2 boundary reference lines.

Stretching these will affect the shape of the stair - make one end wider or curve an edge for example.
