Spiral staircase

[Phil hunt]

What's the best way in vw to create a spiral staircase, it's not something I have to do much these days but I am doing this for a friend who is having a balcony...basically it's 2m in dia with a first floor level of 2900mm with a central tube support of 114mm ideally I would like to create the handrails and uprights in one go

I have tried to create in the stair tool but to no avail, I could create this manually but I would have thought there's a way to do this. Any help would appreciated. Thanks

The Stair tools have spirals. Look the configurations and choose one, then tinker with it until you like.

thanks peter

i tried the tool but i want the spindels/uprights for the handrail to be vertical

but it seems on the presets they all follow the line of the handrails...

The attached file is a model that i have created from scratch using a spiral sweep and then created the treads as a symbol and rotated them and then set the tread height manually.....

it took some time but it worked out ok

Glad you figured it out. I have also used the Stair Plug as a start, then Ungrouped it and fiddled around to get exactly what I needed.

Thanks peter

I didn't know you could ungroup the model created in the stair module.... I don't think I will be designing to many spirals in the future although it has been fun creating the model although it did challenge my maths !

You can ungroup any complex object. Of course the object will lose its parametric capabilities... But sometimes it's a good way to get close. Often I make a copy before ungrouping, so I can go back if needed.
