Can't generate stairwell

[DSKray]

I am trying in HD Pro to generate a stairwell for a stairway leading from the first floor to the second floor of a two-story house.  The Auto Stairwell tool doesn't show up in the toolbar, which I read in Help is a sign that there is no living space above it.  But, as far as I can tell, there IS living space above.  I also tried to generate the stairwell manually bit without success.  I put a railing around the area on the second floor and created an open below.  From the second floor, you could see the ground through the opening and from the first floor you could see the sky through it.

 

Can someone help me understand, first, why the Auto Stairwell tool doesn't appear on the toolbar?

Thanks for your reply but I selected the stairs and still I do not see the Auto Stairwell tool.  Am sending screen shots of all tools after selecting the stairs.

 

I've added the requested information to my signature.

You will find this tool in the Edit Toolbar.

 

The Edit Toolbar is context sensitive, so it displays things relevant to whatever is selected.

 

You may also right click the stair, and find the Edit Toolbar items there.

 

By default, it's in the status bar lower left of the window.

Thank you!  I find it and it works.

The auto-stairwell tool only works IF there is already a second or upper floor in which to create a stairwell. Only then will it appear as a choice in the "Edit Toolbar".
