Silt Winding Stairs

Hello:

I would like to draw the stringer of a flat staircase 250 x12 following a curve

and have the development of the plate  for the laser 

 

stairs 

2 flat stringers 250x12 

1 exterior and 1 interior 

Step width 800

and 1 90° turn

 

Thank you

I came to add it... too late... :)

Given the shape of the staircase, the development will not be a simple parallelogram!

Hi @ cloce

 

See this link in addition

http://forum.solidagora.com/topic2776-20.html

among other things for unfolding silt sheets

through 3D curves

 

PS: you could post your file I can't open your step

I'm on SW2012

@+ ;-)

Drag the links directly into SW @gt22!!

@ David be3

it's impossible for me to open it, don't understand ;-(

@+ ;-)

It works at home SW 2013, you haven't changed the extension, you're still in . STEP?

well yes I don't understand anything 

 

I don't understand anything anymore I take the link dropped on the screen and 2 mouse clicks and it works???????????????????????????????????

 

@+ ;-(

well after having trouble opening your STEP and I still don't know why it didn't work

now I have it in front of my little eyes

it's not 1 1/4 turning but 2 1/4 rotating

you have your 2 stringers to do

and the worst it crashed SW afterwards...................... good reopening resumption of your step here we are

with the SW file it would have been simpler

so I advise you if you want it

to take the view from above, to make the

1° sketch along your external steps for the external stringer and to make an elevation in surface

ditto for the 2nd sketch but the internal steps

create 4 3D sketches for the stringer heights along the walls created on each surface

then you go to sheet metal by taking the 2 3D sketches corresponding to your stringer

you will have your pieces in sheet metal and unfoldable

Something like that you want?

It's quite hard to do though! The right part between the 2 turning quarters is not easy to make up for aesthetically!!

Hi @ David be3

 

I won't bother trying to catch up with the right lines created

 

In this type of staircase, to harmonize the shape, you have to play with the curves

which + is especially for the interior part of this staircase

 

so go through splines under 3D sketches in support of the created surfaces

and played with the settings of these splines via the appropriate tools

Indeed, I was a little fast. With the straight parts it's a little more complicated.

 

The idea of splines seems pretty good to me. From memory, the height of the skirting board (and therefore of the stringer) must be constant in relation to the stair nosing. So, you can create 1 point vertical to the walking angles and make your curve pass through these points.

Once the curves are created, you can do a thin extrusion to create the stringers.

@ chamade if you do as you say it's not going to be very nice especially on the internal silt

 

You have to harmonize the splines to soften the visual

even if it means having high stringers and not regular stair nosing

 

that's not what you see the + in a staircase

 

@+ ;-)

Thank you for your answers 

I'm going to test it and I'll tell you again

Hello Davis BE3

 

sorry for the late reply

Can you make a development of your stringer?

 

Hello 

After testing your solutions...

I can't do it... it's not a thing the splines LOL

Who can not send me the solid file?

Thank you  

 

@ cloce

post a screenshot or a step to find out where you are

to be able to unblock your situation

 

@+........ one.. Red Beanie

Attached is the WWTP 

This is what I did after I blocked 

Thank you
