Stair Graphics

[Isaacarus]

I am having difficulty getting my stairs to display properly in section. I have drawn my stairs with end with riser selected. The stair will display properly in plan meeting cleanly with the floor above, but in section the riser and part of the tread are shown inside the supporting wall. These elements are well past where the 2 dimensional plan and sketch show they should be.

I feel like there should be a pretty simple solution, but my brain is not up to the task of it today. Can anyone help?

Using the screen to scale it, it appears that you need to adjust your tread length.
When you put the stairs in sketch mode, what does it look like? Does it appear to line up there as well. When you go back to the model view, if the stair is embedded in the floor and your cut plane is above, you shouldn't see the overlap, just as if you stabbed a knife into the side of a peice of cake and then looked at it from above.
If you could show a screen cap of the stair in sketch (edit) mode, it would be helpful.

Show the last tread and riser. Not just the riser. Then make the stair end at the 3rd tread. The issue is that you are changing construction types and the last riser is really the foundation wall.

I am posting a few more screen shots to help illustrate the problem. The first image is of the stair sketch in its proper plan location. The next two images show what happens when I force the riser into the right location. The stringer will not extend to the support wall. Also note in the plan view there is now a gap of a few inches.

It seems that the plan view of a stair or a sketch view will not take into account how the stair is actually constructed. In other words Nosings Tread depth and Riser thickness are never taken into account in the Plan Graphic representation. In my case the plan view shows only riser lines that are 11" apart. In the section because of the nosings when you measure the over all tread they are 12". I still can't figure out why the stringer ends where is does.

Is there any way to show the total depth of the tread and show a dashed lines for the riser in plan? I need to be able to dimension tread depth in a plan view and all the program is displaying is a single line for a riser.

The plan view always shows nosing-to-nosing.

When you omit the top tread (and riser) the top step ends up being 1 nosing shorter than the others. (I think this is a programming mistake myself.)

But your issue as I said isn't the stair. It is how the top nosing is created. See attached.

Where the stringer does not make it to the wall, you can just extend the green boundary edges of the stair to extend the stringers.

As to the stair riser or tread endings, you need to move your stair to accommadate the last risers thiskness: or in the Type Properties dialog box for the stair, change the Riser to Tread Connection value to Extend Tread Under Riser under the riser group parameters.

To finish the nosing at the top riser meeting the concrete foundation/floor, Aaron has shown you the way.

Thanks for the help. I think I get it now
