Filling space under stairs

Anonymous — Tue, 23 May 2023 13:16:54 GMT

I tried with Fill Tool but got no results. I need to fill marked (with red line) space.

I tried to do something like trim to roof (trim to stairs ) and with SEO tools but neither gave me a result

Hi,

Can't see the red line in that picture, what exactly are you trying to do? fill the gap between the stairs and the floor?

The fill tool is 2D only and will not yield any results in the 3D window.

Use the SEO's.

1. Create a slab extending under the stair and walkway at the desired locations. You could even use the slab you've created for the walkway itself. (although in you're photo it appears to have 0 zero thickness)
2. Set the bottom of the slab to the top of the floor below.
3. Select the newly created slab as the 'Target' in the SEO dialog box.
4. Select the stair as the 'Operator' in the SEO Dialog box
5. Use 'Subtraction w/Upward Extrusion' method/option and Execute

Did you try to just draw a wall at the edge of the stair and sidewalk?

Place the bottom of it at the same level as the bottom of the stair.
Make sure it is taller than the sidewalk/landing and use SEO to trim it to the underside of your stair and sidewalk/landing.

Sidewalk and stair = Operators, Wall = target, Subtraction with upwards extrusion.

Personally I'd recommend only making the wall/slab the maximum height it needs to be - no more. In this case do it to the underside of the landing. You will end up with nodes floating around in unexpected places otherwise, which can be confusing/untidy.

Also if you make it too tall it will require one extra SEO from the landing itself to chop it down to the required height. SEOs slow things down so don't create unecessary work for the computer to deal with.

You only need to SEO with the stair.

Cheers,
Pete.

I thought the slab was set at 0" thick?
Anyway,
Where is the extra SEO? Do you mean oporators?
Could you tell me more about the slowdown with extra SEO's?
I did not know about this. I could use a lot less of them if it will help speed things up.

If it were a mesh you could slope those steps to let the water run off and it would be all one part.

Hi Steve,

In your previous post you recommended using both the sidewalk and stair as operators. What I'm suggesting is if you only make the wall the same height as the underside of the sidewalk (the raised landing) you don't need to use the sidewalk to trim it, therefore one less Solid Element Operation for the computer to remember. Ok, I appreciate this one instance wont make any noticable difference to the speed, but if you have several hundred unessessary SEOs all over the place I suspect things may begin to lag.

How many SEOs are too many in a project? I don't know. I expect there would have to be quite a number to seriously impact performance. It would also depend on your computer specs.

What I'm trying to say is it doesn't hurt to be tidy and efficient!

See here for example of slowdown:-

Cheers,
Pete.

BTW- I don't think the landing is just a surface, the side facing us is textured the same as the wall behind

This is correct (maybe there are more ways but I made it with this one )

Thank you all guys 🙂

Perhaps I should raise my rates so I can go there someday.

Up to $15,000.00/night. Wow.

Thanks for the links. I really enjoyed the virtual tour hi-res ipix, and room photos. They may make for excellent examples of set up views for rendering of interiors. I wish I had the time to model and render one of those rooms.

The walls of the Royal Suite were very interesting to me because I have just figured out a way to model that sort of ornamentation with ArchiCAD.

We can do a few fun things like this in ArchiCAD, however, there are a number of new photo to model programs that are even more fun.

They will change the way we use ArchiCAD.

Before a person spends too much time developing GDL scripting and ArchiCAD modeling skills, they should take a look at the future.

Check this out. http://www.photomodeler.com/index.htm
Free Demo too!

Another type of technology I think is going to change the way we use CAD programs for rendering is MODO. Programs like this are something very different.

It is kind of a mix between a state-of-the-art rendering programs like Maxwell, Renderman, etc...and Photoshop type editing.

I think the idea behind it is to render whats best as a render, and photoshop (I don't the right word) the part that is better done like that.
?? I don't really know, that is just my observation from the Demo I am trying out. Lot of fun. Very high quality images in a short time.

Thanks Peter, for that link.

I think my over use of these SOE things has been slowing me down.

Hello Steve,
So how do you model this type of ornamentation with Archicad ?
Thanks,
Peter Devlin

Re: Filling space under stairs

Steve Jepson — Thu, 16 Aug 2007 23:03:21 GMT

Peter Devlin??
In my book, you are one of the best ArchiCAD modelers in the world!

You need me to tell you how to model something like this, like you need another hole in your head. You are just curious as to if I have actually come up with something new, or if it is just old stuff. Right?

Sorry, it is nothing you do not already know how to do.

For those of you who do not know about the amazing skill of Peter Devlin let me tell you. He could make a smart part for ornamentation of this type that would let you choose from hundreds of different the patterns, if he wanted too. Similar to the way you can pick different door profiles.

Besides, I have been catching hell of late from the "experts" on this forum for not saying things right.

Let an "expert" explain it.

Read a tutorial on making site models from topo maps. Same sort of thing, and then tweaked a bit.

Hello Steve,
Yes, I was more than curious that you had come up with something.
The only way I would know how to truly model that foliate architrave
would be to use the mesh tool and that would take forever.

just some magic wand stuff, The parts are added to other parts, viewd in 3d and then saved as .gsm. Rinse and repeat, rinse and repeat.
A 3d cutaway on a solid that has been SEO'd, in hiden line mode can give you some lines to to work with, with out ever drawing anything. more copy and paste than anything.
