live 3d section video?

[Anonymous]

Is there a way, in AC11 or any other program, to take a model (made in AC11) and create a rendered movie of a section plane moving through the building?

In effect, much like moving a section plane through a model in SketchUp, but with the graphical output rendered rather than like SketchUp...

Yes, I should have been more clear. It can't be easily done in ArchiCAD. I wonder if that wins the longest workaround award?

I thought about using the Section Tool in 3D from the Special menu, as well as a solid op, but both methods seemed a bit far fetched. Guess I was wrong!

Cheers,

I remembered in the GDL cookbook 3 There is a short piece of code that uses a moving cutplane to cut a building pre-saved as a library part.

It's in section 2, page 193 if that's any help.

It might be a good starting point for someone to add extra control to?

Artlantis Studio will do it like you describe it.

Is there somewhere I can read up on how? If its Artlantis im sure its fairly simple. Thanks!

Definitely. The Ray Harryhausen achievement award.

Another possibility would be to render one frame for every foot or so of the section and run the views in an automated slide show with a dissolve transition between the slides. Powerpoint, maybe.

Artlantis is the way to go for a full animation. Apparently, the Clipping Box camera parameter can be animated in the timeline. Haven't done it myself, but I think it would be pretty painless. You would set the clipping box in one position at the start of the timeline and then set it's final position at the end. Artlantis would interpolate the movement in between based on the length and frame rate of the animation. As usual with Artlantis, documentation on this is very thin. Even "The Missing Book" touches on it only very lightly.

THe problem with Artlantis is the lack of documents. What you do is turn on and set the position (in a 2D view) of the relevant Clipping Plane at the beginning and the end of the animation (as well as other transitions you may want). Artlantis Studio makes all the in-betweens for you.

maybe little late , and out of topic ... but this could be achieved in Artlantis - Studio using clipping box .

Whew...this is all overwhelming to me....Im not that advanced a user yet. I hate to be a bother but could I perhaps get a more mid-level explaination?
I think I somewhat get the main concept: each frame would have the section plane move just a fraction more, correct? I know I can manage this, but once you get into the cameras, key frames, etc stuff then I get a bit comfused as Im just in the past day or two beginning to explore this feature.

Thanks for all the input!

I distinctly remember doing exactly this in GDL in Archicad 6.o or 6.5 ... but for the life of me, I don't remember HOW ...

The animation part is simple - you just rebuild for each frame - but the cutting plane moving a distance for each frame is another thing. Obviously I forgot my GDL ... and no, no SEOs at that time.

AAAARGH! I am getting old ... can someone check whether there is a CUTPLANE GDL command?

I'm trying to drift a wireframe block having magical SEO powers through the model using the current frame count [N_] as a displacement factor.

The 3D script looks like this:

dispx = N_
Addx dispx
block a,b,zzyzx


The block disappears after one frame. Duh.

Help us get our own "Clipping Box"

Yes, it needs to be done with the CUTPLANE command the way Djordje described.
