AC21 - stair's structure and finishing

[alemanda]

Hi,
in my workflow I usually draw the stairs twice. One stair is the structure and the other one is the finishing. I put them into 2 different layers.
during the stair editing if I disable the finishing, the structure actually takes the place of the finishing. Actually I need the raw structure ... I mean I need the structure as if the finishing is there ...
In order to get the proper structure geometry ... is it possible to define the structure of the stair as if the finishing was there but without finishing?
...or the only solution is just a SEO between the finishing and the structure?

[alemanda]

Finally I solved duplicating the "finishing" stair and modeling it so that the risers and treads of the "structural stair" were 30mm after and 50mm below respectivley the risers and tread of the "finishing" stairs

Well, yeah, the ability of Stair components to react to changes in Partial Structure Display settings is another topic, which should also be addressed in my opinion.

Yeah! It would be a great time saver! Just like the possibility to add a plaster skin to structure automatically!

[alemanda]

Actually the plaster skin is a big deal ...
Plaster seems to be an against-BIM item ... How to handle it consistently with original BIM approach?
Maybe this is another topic and deserves to be discussed separately ...

[squall_tmo]

Yes, you are right: it's probably the subject for another topic!

Anyway I think it can work if it works for the columns...but it surely need the 'partial structure display' improvement, so maybe it's even too soon to talk about it!

actually I'm not a fan of partial structure display ... I think the most proper way is to keep structural model, architectural model and MEP models separated. This will allow a better documentation.

Hi.
So... how did you end up solving the structure-finish issue?

And a little bit off topic... I also think that two separate models (structural - architectural - MEP) is a good way to coordinate and document a project. To me, partial structure display helps a lot in this regard, as it allows to compare the load bearing part of the architectural model with the structural model. The only thing I'm torn about partial structure display is the separate sets of annotations: sometimes it is great... sometimes it means duplicating annotations.

Do you ever use partial structure display? A bit of insight to workflows is a great learning resource.

Best regards.

External finishing is almost always modeled.

Internal finishing almoste never ... many times I use the zone stamp.

I never use partial display.
When I have to provide also the structural drawing I model the structure in the same file.

Annotations. Well, annotation are almost never duplicated. To do this I play with the layers/layers' combinations

Just today I was reading a document about layers and layers theory ... I'm thinking of changing my template basing the new system on a classification system (ominclass maybe) but it's huge work and needs time

I meant the stair structure-finish issue... sorry.

Layer combos work if you don't use partial structure display. Since each partial display has its own set of dimensions, it can be helpful in some cases and a nightmare in others.

Best regards.

I wrote it some posts ago ...

[sinceV6]

Yes... but didn't quite get what you did

What I understood is that you solved by using the finish stair twice, the second one used as "structural" and tread and riser parameters modified. Is this correct?

Thanks.
