@Franck51, you should put this beautiful file in a tutorial so that everyone can enjoy it!
Sorry
It's not that I don't want to, but these documents are confidential.
With our Excel sheets, we calculate all the dimensions of the parts, but we also generate the programs for our numerical controls.
Sorry again

Good evening
I try to make a sketch by steps but no way to get a result
If someone has a model I can look to make one and print the stringers and steps after modifying the dimensions.

Hello Hrey
Send me the configue of your staircase and I'll look to see what I can do.
Maybe I could model the staircase and send it to you in iges for example.
Kind regards
I advise you to create plans to delimit the size of the staircase (2 parallel planes for the departure and 2 planes at 90° of the others for the arrival of the staircase. On these plans you build the edges and after, the steps against the risers etc.
If it's not clear, you can write to me at alain.viard@riotinto.com.
Good luck
well after a few hours of work
and headaches

the same with its external stringers

Hello gt22
Great directing, on my side I tried too.
I think there are simpler things but it's a start.

Hello hrey
Here is the version of your staircase quickly made in 5 minutes.
I'm sending you an idea of the staircase as well as a 3d pdf.
If you can't get it back, give me the format you can get back and I'll see how to send it to you.
The export turned the curves into a rough right-hand section, I apologize.
Kind regards
Franck

Hi Franck51
after download
you have a problem with the length of the tread
and your first balanced walk which from above seems very fair to me ;-)
Hi hrey
your staircase has no swinging steps
@+ ;-)
Hello GT22
My staircase has many swaying steps, but only 7 steps.
It is an industrial staircase for which it was chosen, not to do a total swing, but only partially.
So for the treads it is the same in the swinging steps, this one is bigger. (In the standard it is only specified that the tread distance between the balanced steps and the straight steps may not be less than 10 mm. With my design, it always feels bigger.
Kind regards
@ Franck51
After downloading and converting this is what I see
something bizzard the sides between my 2 green dots
1199.71 mm and my stroke at 400 mm
so OK my line is not quite in the axis but still it surprises

In the thread I didn't want to be unpleasant in any way
have a nice day @+ ;-)
No problem for me, I didn't take your remark in an unpleasant way, it was just to explain to you that I design "industrial" staircases and not artisanal staircases.
Then the width of the flight is not 800 but 846 (I'm not sure of the dimension anymore).
So your green dot on the left should be moved outside the stringer and not positioned inside the post
I don't see what your 1199 line corresponds to?
Well, precisely
my line of 1199.71 is the odds between posts
and 400 my axis not in that place I grant you but 1199/2=~ 600
after checking I just noticed
-that I misplaced my points with the evaluate and measure tool on SW on the front view
788 Measure between silt

Hello
I am also starting to take an interest in the subject of the parametric quarter turn. I read and tried to follow the different posts on this forum and a councurrent, without finding all my little ones:
As much as the vocabulary, it's starting to get good, but I haven't found an explanation on the correspondence between the "stair template" file in solidworks and the "stair stair" spreadsheet offered for download. In order to start with the parameterizable, I think this link is essential, in order to transcribe it into the SW equations perhaps.
I was wondering how the different attempts on this subject were, hence this topic digging.
Thank you

Hi @tecnao
I was able to open Excell but not your part of the stairs
@+ ;-))
Hi @tecnao
Can you be more specific about what you are really looking for.
I work with Inventor and create parametric industrial staircases using excel sheets.
If I can help you, there's no problem.
Don't hesitate to ask.
Franck
PS: can you put your file in a format readable by any type of CAD (Like step or stl for example).

oops, sorry for the late reply, wrong subscription settings as the discussion progresses.
In PJ the SW file in step format, but almost only sketches, not sure if it will pass in step.
Otherwise, in summary, I'm looking to design a simple 1/4 swinging staircase, but I'd like to take the opportunity to do something parametric in order to adapt it if the demand emerges a second time one of these days.
To advance the schmilblick I started to draw a balanced 1/4 turning using the harrow method to calculate the swing, but the result was frankly not ideal aesthetically to have an inner stringer as I wanted it (not very aesthetic breakage).
So I resumed the swinging to limit the number of swinging steps, and go from 10 to 5. Here, the result is much more adapted to what I wanted aesthetically, but probably a little less comfortable.
The change from 10 to 5 balanced steps was unfortunately not done very easily, with many unresolved constraints, to be redone, ... This is where the parametric side would have interested me: to be able to correct just the parameter of the number of steps balanced and that everything adjusts automatically. But maybe I'm asking a little too much. So if you have an idea on the process to follow to achieve this goal, I'm interested.
And if my extrapolation of the 5-step swing is messed up, I'm open to any constructive comments. If Franck wants to see what it would look like with his Inventor configuration, the input data are:
Finished height: 2.91m
staircase width: 0.95m
First quarter length low (I already don't remember the technical name and am too lazy to search): 1.70m
Length second quarter top: 3.49m
Thank you.
