hi David fano !
can you show me the way to model the bejjing national stadium?

Here you go

Hope it helps,

Dave

Thanks for your help, i'm a artchitecture student. I want to model complex building and i hope you will help me in next times
Thanks again!!!

No Sweat if not me hopefully other people will start to contribute 

I lost my initial post...so here I go again...

1st of all - Apologies

I apologize for providing a revit post to a 3DStudio thread
I apologize for the type of attachment I provided(size and that it is a doc, not a jpg - my home computer has no programs allowing me to post a screen capture)
I apologize for not providing the revit file (I am at home, where I have a demo version...and cannot save)
I apologize for the inaccuracies of the model...it was just a fast test of a thought I had

Ok, now...

1. I first created a shape in a family (I used a swept blend for half of the shape, and then mirrored it)
2. I then created a reference line in Plan(added an instance parameter controlling the angle)
3. and a reference line in elevation (added an instance parameter controlling the angle)
4. I then created 2 voids (large enough to cut the whole project) off of the same plane (1 of the 4 possible planes provided by the ref. line (in elevation)
5. Loaded the family into a project
6. created a schedule with Mark, Angle Plan, and Angle Elevation
7. copied a few of the same family in the same exact location
8. began controlling the geometry by modifying angles in the schedule

Hope this is interesting to somebody...it was to me.

As soon as I am able to reproduce this using my computer at work, I will repost and clean up the attachement...

Take care,
Luigi

sounds good. I'd like to see the file.

Should i move this to the challenges?

Thanks again,

Dave

Reading the intent of your "projects" section of challenges is what caused me to try this one in Revit...so I guess, even though I posted here, my mind was on your challenges section.

Just got around to opening the file. This is Great!!!! Can you post the images so i can post them on the blog?

Thanks,

Dave

I'm not certain if this is doing exactly the same thing as the Bird's Nest but it's a start;

1. (Blue) NURBS massing of skin.
2. SurfDeform (WSM) Modifier applied to (Green) Plane Object.
3. Go down the stack to adjust Plane Object to fit massing.
4. Plane Object used as template for (Blue) Spline pattern (this one tiles horizontally). Apply Normalize Spline Modifier to allow it bend. Apply Sweep Modifier.
5.  Instance of the SurfDeform (WSM) Modifier applied to Spline pattern.
6. You can duplicate the Spline pattern and play around. Perhaps slide pattern around NURBS massing (U Percent), experiment with layering effects etc.

Great site David, fantastic resource!

Great Solution!!!!!!! This is far better than mine!

Thanks for posting it!!!

Can you post a video about this...
It seems confusing for me :=)

Thank you

Ok, I got around to recreate what I couldn't save earlier

See below an image modeled and rendered in Revit.  Obviously i didn't spend much time in placing each member, I just randomly gave Elevation Angles and Planar Angles...just for effect. 

The sequence of what I did is in my post above.  To make it more realistic though, all one would need to do is give the family an X and Y Offset Parameter...this would give the design more flexibility (as obviously the actual design provides)...each component's Planar Angle is currently fixed to the center of the project.

In addition to the image I have included an "empty" project file(rvt) with the "placeholders" and the single family(rfa) used to create the geometry.  (I created an "empty" project file because the size of this file is too big to upload)

All one needs to do is download both the rvt and the rfa file.  Open the rvt file and load the rfa family into the project.

Thanks for posting this. This is front page material!

can you show me a clear intruction?
or make video tutorial about modeling Bird's nest stadium in revit
thanks

Thank you David 

I don't want to beat this particular Revit solution to death, but...

I have attached some additional features to the family.  As I mentioned before, I have added the X and Y offset to where the voids cut the solid...allowing the members to not only pass through the middle of the solid.

I also added the X and Y Radius of the elliptical path as a parameter (as a type parameter)...allowing some minor control over the solid  (I decided to do this after noticing the members of the actual project aren't always only on the exterior face...they not only are completely inside the exterior face, but also start from the exterior face and end in the interior....

The example I have posted has a few members with the X Y offset (both positive and negative offset...where the top/right quadrant, if you will, is the positive/positive one.)

2 of the 100 members ahave a different X radius than the rest, allowing these 2 members to start on the exterior and end up 6' to the interior.

The only thing this solution would need is to control the 2 profiles being used for the main solid shape...

To Phamlemon, I might be able to provide some screen captures of step by step, and maybe even a video clip...but I don't believe it would be right for me, or others, to upload videos to this site...this is David's territory....he might provide some short videos of some of the very simple concept needed to make this family....  but a step by step solution was posted (and will update with the added features) on a previous post of mine here, and at AUGI http://forums.augi.com/showthread.php?p=868376#post868376

Take care,
