Hi Rune,
Ok, I re-optimised the stringboard as when you make changes, this custom change might disappear, and it did. Also, reset the best position for the step in the turn to have the best aesthetic result.
Attached are the files together with the design file.
Do not hesitate to share your experience with us with pictures and a small testimonial. We would be glad to share this experience on our website

Hi Michel,
I confirm the design is correct.
Even though flight 1 length is reported @ 3011mm, the actual string length is 3011 + “length beyond the last step” = 3157mm.
The straight steps I have cut are indeed 286.77mm – ie 240.77mm tread + 20mm nose + 26mm riser space.

Hi Rune
You have to be careful as you say tread width 240,77 is the going of the step. The actual step is 286,77. With a demo version, you will not be able to see the finished dimensions of the parts. We will provide this with our stairfile once the design is finished.
The total length of the flight is still 3057 in this design. I do not see any extension here of 10cm. The flight is 3011mm, and the last step is 146mm.
Can you check and reconfirm?

Hi Michel,
Happy new year to you too – and thank you for your feedback. The string looks a lot better now.
I updated the design with a larger well hole as it is not a problem to remove 10cm of the upper floor at that end – I already started making the straight steps so I cannot change the tread width from the 240.77mm.
I had also taken into account about 5mm spacing with the 3057mm well hole length.
Attached is the final design – please provide stairfile for it.
Thank you for your support!

Hi Rune,
First of all, Happy New Year!!
The stair should be ok but I always advise to allow a little play in the stair length in order to be able to put into place. 5mm should be enough. So, 3057-5mm play
In your setup, the last step (landing step) is only 46mm long. You could think of reducing the flight length to 2911 and adding a 100 overlap on the cut stringer to create a last step of 146mm, which is more comfortable, and you still have a comfortable step on the rest of the stair.
Here is a version that I made. I also corrected some geometry of the inner cutstring to have a nice shape and connect properly to the floor. Some step windings also change in the corner for a better result.
You might need to upgrade your software in order to be able to read the file. Here is the link for it if needed.

Hi Michel,
to further elaborate, I had to design the stairs with 46mm shorter length than the actual well hole, ie 3011mm instead of 3057mm. Then I simply added a manual string extension and everything seems ok – both 2D and 3D.
The well hole is still defined to 3011mm in the design file but I guess that can be ignored.
Since I cannot see the actual measurements in the demo version I basically just need you to confirm the designed stairs look ok and would fit in the actual well hole of 3057x890mm and floor height of 2684mm.
It should be ok from what I can deduce using the visible coordinates?

Hi Michel,
here is the designer file to go along with the image. I added a landing and removed the manual extension to show the problem.
I have defined a well hole of 3057x905mm. If I also set the right cut string length to 3057mm, the 2D drawing of the string shows the top step to be too short by 46mm (no room for a riser due to the well hole).
The 3D drawing of the stairs (image in my previous post) shows an impossible solution with the top step extended into the floor.

Hi Michel,
thanks for your reply.
I have tried to draw my question in the attached image. That is what happens when I do not add a manual extension to the cut string.
I think the stair design looks ok with the manual extension of the cut string by 46mm, but I want to make sure I did not do something wrong to cause the string to be shorter than the stairwell.

Hi Rune,
It is unclear to me what your point is on the room for a riser. Do you mean a landing step on top of the stairs? Could you explain it in more detail or sketch it so we can check on it and add all the details to the design?
regards
Michel
