stair landing problem. Problem and Workaround.

[jagostinho74]

Hello,

Due to core shape, the following stair needs to be modelled as the image below.

Stair looks ok at floor plan but in 3D it looks different. A hole comes up on one of the half landings.

Workaround was found by breaking the stair and, hence, creating this warning.

Edit stair.

Delete last run and landing.

Edit intermediate run. Drag grip to remove last step.

Add last run again.

Convert half landing to sketch.

Edit landing sketch. Adjust half landing as image below.

Adjust landing relative height to accommodate +1x riser height.

Convert intermediate run to sketch.

Add missing step.

Adjust landing height again to correct landing relative height elevation (???!!!)

Finish stair

Add in-place component for missing triangulated infill between intermediate run and landing.

We are very keen on having as few warnings as possible in our projects but could not work this one out.

Would have you done it differently?

RVT File attached with problem stair and workaround.

Many thanks.

Hi Joaquim, 

Thank you for posting this on the forum, 

This does seem to be a really odd behaviour and it's easily reproducible.

I've gone ahead and documented it for our development team and I'm sure they will be looking into it really soon. 

As to your approach/workaround, I would personally have done it they same way.. 

There might be some trick, but it seems that whatever you change, as long as you have the run end with a riser, the solid will be cut in 3D view. 

I also noticed the cut represents the angle of the riser below so in some way I suspect the conflict to originate from there. 

I will update the forum thread with an incident ID along with an article, the article should be ready within a day or two. 

Again thank you for making us aware of this, I hope you have a great week!

Hi Joaquim, 

Following up with you regarding this issue, 

I have published an article regarding the issue you made us aware of. #

There's a unique incident associated with it and it's "104222". 

Here's a link to the article I published, it should be ready within a days time. 

• Users reported that stair geometry gets cut when the run has an angle to the landing

You can track the status of your request through this article and refer to it if you're speaking to one of my colleagues. 

Thanks again,
