[PR] [0.18-0.21_pre] Arch Stair - More Geometry Control? Profile Generator

[paullee]

Still stuck...

For fun, play with simple experiment to build a box theatre like model ...
... mainly on 2 master sketches
... 1st with 4 edges for the theatre enclosure
... 2nd with 5 edges for the steps

Need some more features to add to make the model more refined

cool!

[paullee]

Thanks, slightly modified version.

Hope can find some seats to put in In addition to finding some potential features to add, found some bugs too

Ok, it seems I have made up my mind on how to do 'Profile / Face / Solid (BIM Object) Generator'.

How would you like to do a curve audience steps below?

• Still 3 simple straight lines - like the previous rectangle steps - representing 2 'flights' and 1 'landing'
• 3 ArchStair Objects with the 3 lines as base - still same as previous
  
• Now, Stairs has options like StructureOutput, StepsOutput ... that you can pick Profile, Face, Solid (BIM Object)
• Pick Profile and Stairs only give you profile, instead of the default 'rectilinear shape' stair flight solid
• Do whatever you like with the Profile (like Revolve in this case)
• (House the solid in an Stair Object as desired)
  

It seem much simple this way than to add 'more built-in features' in Stairs.

Any comments and ideas?

Then, the Profile should be 'editable' to let user fine-tune / adjust the 'default' structure / steps / risers profiles ?

In fact, just as simple as 1 line should do as Stairs has a 'Landing' attribute... just pick 'At center'

No need for 3 lines ... hmmm, just find a problem that the 'landing profile' is not produced in this way yet...

OK fixed - 1 line to create 2 flight + 1 landing

But with more more lines, one can tweak different risers height for each 'flight'

Hi, anybody know how to design a theatre? Just imitating some online images to test out the idea of using Stairs ...

Here is a typical section. This one is of Libeskind's Grand Canal Theatre in Dublin.

And he is a Revit section of a theatre I worked on that has a similar cross section:

And here is the process of building theatre from a 2d cross-section, similar to the way you are building them, while making sure it works with the sightlines, and then sweeping the cross section along a profile (Curved or straight)

[paullee]

Thanks for the drawings!

It's good the section has some dimension and sightline illustrating the considerations and provisions

Have you looked at the wall creation in Blender with the architools addon? It's not 100% intuitive, but it does a pretty decent job.
