3d model rising out of architectural floor plan.....

Anonymous — Thu, 11 May 2023 12:42:31 GMT

Ive always thought it would be a neat presentation technique to have model or partial model rising out of "the architectural floor plan"

Has anyone had any success in doing this.
Would they like to share the end result and how they did it?

Thanks again.

That's a complex situation. I have only done parts of it......

Alternatives:

You do have the Construction Simulation Goodie. I have never used this.

Then there was the Aftermarket Object that took a GDL object and scaled it vertically in an Archicad animation. It worked well and was believable if buildings were rubber.

In Artlantis, it is simple enough to animate the scale of any object - you could make a thing flat, then move to its proper height. The components cold be timed with key frames.

Of course, this can be done with a combination of tricks, including an animation of the vertical scale, say, of building columns, then floor plates, then use a slide show to cross fade into successive images having additional building components to complete the building. After all, we see buildings rise up daily, but only as far as the frame goes - then panels are added whole.

As far as the floor plan goes, you would make a surface skinning material of the floor plan drawing to complete the effect.

Sorry for the hypothetical nature of the reply....

Depending on your desired results it should be pretty easy. Just save your floor plan as a DWG. Then use the Open Object command to open that DWG and then save it as a (GSM) library part. Place that libary part so it aligns with your model. It wll be visible in 3D and you could use SEOs to show your model rising out from it.

Cheers,
Link.

Great image, Link. Sad that Microsoft Windows' cheesy 'tada' sound comes to mind upon seeing the graphic. 😉

Cheers,

I assume Lennox needs an animation of some kind.

Since we went through this last year without success, did anyone finally manage to animate a cutting plane or SEO?

You could create a simple animation, using Links technique and 3D cutaways to create a series of images and then stitch them together using Adobe ImageReady or something similar.

The bug from last year involving the image not being rebuilt when the cut plane was moved in the GDL script was confirmed by GS. I kind of remember seeing that it might be fixed now... but have not tried it again in the latest build of 12 to see...

Here's an untested hypothetical... proabably on the same lines as the cutplane, but why not....

1. Create a 3d object (slabbish) that is set as the boolean OPERATOR on your entire building (most likely saved as an object itself)

2. In this object you can have it's height variable by frame number

3. Insert Link's DWG plan (not cut by operator)

4. Set layer of cutter to WIREFRAME (or simply apply INVISIBLE material) so it never shows in rendering
a. on the other hand, make sure it's on a wireframe layer and give it a material that you can use as the CUTPLANE Material for the house i.e. when the building grows up, the edge of cuttedness is black or Richard Meier Orange...

5. Render....

If you use Subtract w/ UPWARDS extrusion, placing the cutter below the lowest part will show NO BUILDING until such time as the bottom of the cutter passes the bottom of the building.

Sound's like it should work!

Thanks for letting me play

A quick test shows pretty much what you're after....

One caveat....

1. Had to use CURRENT FRAME - START FRAME or the multiplier went too quick (didn't start on 1!)

Excellent news!!!

Now, what was that GDL object that scaled the model vertically in an animation?

Re: 3d model rising out of architectural floor plan.....

Dwight,

Not sure which object you're referring to.... but

1. Save BUILDING model as GSM (BINARY will work better)
2. Add Parameter | Real Number | FrameGrowth
3. Insert into 3d Script at the beginning.

IF GLOB_FRAME_NR > .00001 THEN mulz (GLOB_FRAME_NR-GLOB_START_FRAME)*FrameGrowth

Should be that simple...

Great that the bug is fixed in 12, Duane! I just opened the test project that was filed with the bug report a year ago to confirm the bug fix - which you demonstrate too.

Here's the old thread just to link it to this one:

This looks extremely impresive!
2 VFRONTIERS: could u please give some more explanations on the technique for "not so pro" who tried annimation just once... What is "multiplier" and what makes invisible object move up?
Thnx a lot.

The object is SCRIPTED to add a certain distance EACH TIME THE RENDERING increases 1 frame. So you will need to check the box ... REBUILD MODEL FOR EACH FRAME in the CREATE FLYTHROUGH dialog box.

The object becomes INVISIBLE by placing it on a LAYER that has been set to WIREFRAME. This is done in the LAYER DIALOG box by checking the the extruded polygon looking icon. It will change from filled in to empty showing that it is wireframe. You will be able to see the objects on this layer in the 3d window, but NOT in the rendering.

Hope this helps...

Duane,
I tried your techniqie but with every try of pasting the line into object's script and rendering it I get error massage (see JPG), although the object says "3d script is OK!" after pasting the expression.
What am I possibly doing wrong?
Thanks

Did you save your DETACHED HOUSE as a BINARY GDL object? If not, you should... If you did and it still gives this error, it's probably a door or window and will probably render fine, just turn off error reporting...

I looked up the object that animates an object.
It has three settings - shown below is "rubber" - also "Growth" and "Construction"

The original file is SO_Animation.PLA containing several useful animated objects. It dates from 1999.

Whose is it? Is it commercial? Can we distribute it?

Click the image to see the animation....

I have a vague memory that it was DNC's. Not sure at all though.
