Allow Boolean Cut Void Operations on Stair Components

[timwaldock5907]

I would like to be able to create void elements in the component stair edit mode, and then use the voids to cut shapes out of individual stair components - WITHOUT converting the components to sketch.  This would mean that you could create irregular shaped stair components that retained their component capabilities (such as shape handles).  At any time the stair component could be modified as normal (add/remove risers, adjust height etc) - they would just work around the void so that part of the stair component would be cut away; railings would adjust around the cut shapes.  The voids could be removed or modified to change the shape of the component.

This would allow us to create such things as tapered stair runs (with triangular voids at each side), landings with notches cut out of them etc.

Hello from Spain.
Its a common issue of discussion the lack of interact of stairs with other entities, like walls, voids, masses....

It would be a great improvement the ability of cutting stairs with voids, openings, masses....
For example, in building reform is usual to have to cut stairs in order to place a lift. Now I have to model two adjacent stairs, both in existent phase, but one will be demolished in new construction phase.

This means  work twice, it would be faster to model only one stair in existent phase and cut it  partially with a void in new construction fase, this would permit the right documentation of the stair in both phases,  construction and demolition.

Regards.

Why we can not have an opening in stairs (by component or by sketch) for some design needs.

this opening can be a shaft opening or just an opening like wall opening or be able to add an opening within the stair sketch.

Hi, There are already two topics on this. Please check before posting:

Great idea. 

Even when using stair by sketch there are situations where being able to cut stair elements would be beneficial. For example recessed light fixtures in terraces.

I think this has been mentioned in some other Ideas posts - but if this were to be actioned I'd also like to see "join" work between stairs and walls at the same time.

Are we discussing/proposing the same thing?

Being able to cut voids is critical.

We frequently have  services in the fire stairs (like hydraulic pipework). If we can't cut voids, our clash detection will pick up false clashes.

We can use floors for the landings, but the flights don't connect well (and Cut Profile isn't an option in elevation views). Stairs are then unconnected and don't annotate correctly etc etc.

I don't understand the logic of not being able to use a void to cut holes from landings, while floors etc are fine.

Please allow recesses into a landing. If you dont users instead model floors, filled regions and move these every single workstage and between the model is changed.

Further pls stop those infernal popups for feedback, i am giving you feedback and i have to keep clicking close on the feedback dialog.

thanx you

Hi,

Still the same workflow problems, with stairs, users will workaround using stair landings and model notched flight to landing connections. I have seen an example where builders actually built this as they thought it was a stait feature.

Further stairs are built incorrectly becuase in Australia another line at a flight will mean another riser and despite my best efforts to get users to use begin with riser and end with riser, they do not. Further as the landings do not allow model hatch editing and voids for TGSI, or ground indicators that are set down. and they want to show the set downs in concrete setout plans.

Is there a place to submit changes and vote them up.

If this is the place I VOTE FOR IT

Why is there a limit on what categories can be cut? I can think of several other categories that need cutting:

• Temporary Structures
• Stairs
• Railings
• Masses
• Structural or Infrastructure categories
• Columns
• Site
• Topography
• Roads
• Ramps
• Hardscape

Ich würde mir die Verschneidung von einer Treppe im Außenbereich mit einem Geländevolumenkörper wünschen.

I was just asked by a colleague on how to remove a bit of a stair run. We found we could not just subtract a void in-place component despite it being of the 'right' category. The idea is to allow stairs for the boolean operator from the modify tab.

I'm not sure if you would simply prefer a different workflow or if you are having trouble creating a certain condition. If its the latter, you can convert the stair to sketch-based and you should be able to accomplish what you're trying to do.
