The Path Stair command raises some issues concerning how the stair runs attach to landings.
In particular, the "Beam Stair" type creates a landing whenever the V-Line path changes direction.
1. So the first question is how does one create a curved landing?
Suggestion: Add a means to create any shape landing.
2. The second question, how does one control the thickness of the riser run?
3. How does one control the thickness of the landing?
Generally speaking most landings (I've worked with) are co-planar on the top surface and on the under surface. The structure and finish on the bottom of the landing are parallel to the floor not sloped as the Path Stair/ Beam Stair type command creates.
4. How does one adjust the sloping underside of a landing?
Suggestion: Add controls to adjust the "flatness" of the underside of the landing.
If one has two or more landings, each landing follows the same landing offset. This isn't necessarily useful. There are many cases where one landing length may be different from another landing.
5. How to make each landing offset unique at each landing? I've tried the S-split tool. This not only splits the landing but the stair changes from a solid to a surface object. I find it difficult to changes the resulting surface objects back into solids.
Suggestion: Add controls to the stair so that the landings can be "stretched" or lengthened without destruction of the stair.
Sometimes landings tuck under the stair riser runs. This is typical with wood construction where the stair stringers are supported on top of a landing beam or header.
6. Suggestion: Provide a mechanism to recess a landing beneath a stair run.
Note: A workaround for all of this is to create a stair on a layer, ghost that layer, set snap options to "Snap to Ghosted" and draw over the "close-but-no-cigar" stair piece-by-piece on a new layer. Make adjustments as necessary. This allows one to create curved landings, custom railings, correct thickness of stair run structure and landings, tuck under landings, and "non-sloped" landings. This takes some work. It isn't quite the time saver one expects from a Stair command.
Suggestion: Provide an edit mode to edit the stair using the drawing tools.
Well, that's all for now.
