stair against a round corner wall

Recommended Posts

Hello 

 

Can anyone tell me how I can create this stair. Before the curved part I need 11 steps in the curved part I need    3 steps witch must end right, because I must place after the corner

2 steps. My stair is in 90° ( see picture) thanks for the support

There are a couple ways to do/fake this. One is to let the winders be square and then cover the corner with a curve. Or you could use different pieces for each run. Or use a straight stair at the bottom and top and extrudes for the winders. One note, to my knowledge the stair you show will not meet code (US); as I recall the minimum width for tread is 4". But perhaps this is for stage and so does not need to meet code?

so there is not a method to make it in 2d/3d with the stair tool?

You can create it with the Stair Tool (I think), but not with the rounded corner. That will need to be masked with a polygon or round wall, or some other contrivance. Also, not sure whether the current Stair Tool will allow zero width winder treads as you show; I would need to try it/fiddle with it.  Often in these cases (curved & zero width winders, eg) I find it way faster and easier to work with simple extruded forms: Draw each windered tread in 2d; extrude each one and place at the correct height. Then use two separate straight runs of Stair for the lower and upper portions. Yes, you will need to do some math, but that's why they call it work. One trick is to use a dummy stair just to find the height of each riser. That will speed things up a bit.

This is done using a single stair PIO, check the attahced vwx file, the  screen shots show how to control the radiused corner and the number of steps on the winding section.

The stair would be difficult to make and won't comply with the US or UK standards. If its in timber with stringers, these settings wont work in the pio.   131044451_StairImage.thumb.png.d6cc7a0e43e3b081d487c3b978678c08.pngStair_All_PIO.vwx889065183_StairWindingSteps.thumb.png.427415f19510c9fbb93f7c515c4b74a1.png1344550932_StairRadiuscorner.thumb.png.a3c369069a39f37305887a5ca0d7434c.png

Nice work! (I have never loved the UI on the Stair Tool so I lose patience with it pretty quickly)
