I have been trying to create a precast monolithic stair with a short bottom landing. The problem I am having is by adding the bottom landing at the length I need causes the throat thickness to taper. Refer to the attachment "Bottom landing problem".
When I increase the length of the bottom landing the stair goes back to how it should be. Refer to attachment "Bottom landing OK".
The element and type properties for the stair are included in the screen shots for information.
Any ideas?
