Change Line/Arc Button

[TappedAnts]

I cannot find my change line/arc button. I want to curve some stairs. I've look in the available tool bar buttons but can't find it. What am I missed. Thanks for your help.

It is an edit tool, which means it is on the edit toolbar, so you need to have an object selected (select the straight stair section first, because the button won't display until you do) that can have that type of change applied before you will see it displayed.

You can do select it in either your floor plan, or a camera view, whichever is easier for you.
