This is a Revit from Renan Jose, and I'm going to create a staircase from the existing layout.
Create Stair using Sketch, and pick all the lines to create the Boundary and Riser, draw in the Stair Path as well.
Something's not right... don't give up, check the Type of the run.
Change the Underside Surface from Smooth to Stepped
It looks weird but worked.
Now let's see if we can make the smooth option works, try different dimensions with the Smooth option.
Nope, I'll leave it for now, at least it looks okay on floor plan.
Now let's have a look of the other issue, that the Riser at the at the corner is not counted.
It says 17 Risers here, let's count.
It looks like there is 1 missing......
I am guessing it is because there is only one boundary line (green line) to these steps.
Move the Riser lines by 5mm and see if it changes.
It changes to 18...
It somehow broke here, let me fix it...
It goes to 17... maybe do the same to this corner...
Adjust the first step so it also has a second boundary, like a 5 mm one.
Yes, 18 again.
I can't remember what I was doing here, maybe to test the counting once more.
Have a look in 3D.
Now let's try the Smooth option...
It works this time...
As you can see, the stairs are no perfect
This video is only to show you some of my thinking and some experiment about the counting number issue during the sketching.
I saw that ToanDN have modelled a perfect one, I'm also interested to know how he did it.
Hope it helps. Thanks.
