Thanks for sharing more videos on this.

The 2nd video is an interesting one.
The "tutorial" is basicly saying ignore lots of information provided in XYZ files.

It seems that ArchiCAD can only take data in the form of XYZRGB?

Those videos strongly seem to suggest that they have no ability to import intensity values and dont seem to know that it even exists?

The Making of Point Clouds in ARCHICAD 19
Ferenc Traser January 19, 2016
Excerpt:
"What does the future hold? We will have to support intensity in addition to color. Make performance better and be able to import even larger files. In my opinion, we must enable point clouds for any output: it would be an ideal tool for creating architectural context. Recognizing BIM elements from point clouds may be too far in the future, although companies like ClearEdge3D aim to do just that. But maybe tracing simple surface geometries like planes or tubes can be a good way to start. Whatever direction we take, it all depends on you: how would you like use point clouds in ARCHICAD in the future?"

When I used this a few weeks back it didn't support an intensity point cloud. Not everyone takes RGB values on site to save time.

If this is the case then its a real shame but this may have changed now. :geek:

Quick workaround: Convert intensity to RGB with cloudcompare ;)
Of course you loose the original RGB values this way, which shouldn't be a problem if you haven't captured them anyway.
Cheers!

Not a quick work around if you taken 180GBs worth of data but i know what you mean. Thanks for the tip though :D

Is anyone else using ArchiCAD in anger with point clouds yet?

We are finding that the modelling process is quite slow even with good PC's, our experienced ArchiCAD user likes the point cloud data but is getting frustrated with how it clogs up his workflows. We have not used any huge datasets yet either just about 5gb!!

Any feedback welcome!

I'd call 5GB a reasonable size project, definitely not small. I have only imported some data into ArchiCAD quickly and have no real idea about using ArchiCAD but my first impression was that the scan data looked really good in ArchiCAD, certainly better then what the same data looked like in Revit.

For big projects you typically break the scan data up into "chunks", before you import it into your modelling software. Usually it might be broken up into floor levels or just simply breaking the building up into 5 separate regions for example. Then each floor level or region is imported and you can use the point cloud manager to turn off all floor levels except for the ground floor or only turn on region 1 etc rather then trying to orbit or pan the whole project which is taxing on the computer and software. I couldn't find a equivalent point cloud manager in ArchiCAD but that's not to say there isn't a equivalent in there somewhere, hopefully there is.

The other concern I had is the workflow for importing the scan data in the correct coordinate system. It seemed to just place the scan data centrally on the screen and I couldn't find the option to import the scan data in its "original" coordinate system. Obviously there are times when that doesn't matter but there are a lot of times when you want the scan data to be placed in its "proper" location, especially if you have broken the project up into chunks.

Hopefully someone else knows ArchiCAD and can help you out.

Thanks Gregg,
I am trying a strimmed down point cloud and will investigate how the point clouds are placed to check on "chunking" as an option.

Cheers

Hello guys,

you can place a pointcloud in ArchiCAD to its original coordinates in two different ways. Either on import, where it asks to insert pointcloud to its origin or you can select already inserted pointcloud by mouse, right click and pick ¨move by pointcloud origin¨ (not sure about exact transcription, translated from Czech version of ArchiCAD ) and drag to your project origin ie. 0,0,0. Not by far ideal, but better than nothing. The second option should also work for BIM server projects where the first one isn't for some reason available.

The other workaround I use is attaching unified individual scans instead of merged pointclouds. It makes working in 3D view less painful, because I can always 3D view only scans I work on and not the whole floor or building that would freeze 3D view every time I touch my 3D mouse.

ArchiCAD pointcloud engine still needs BIG improvements, but even in its current state it can be successfully used with couple of tricks and actually working with pointclouds in plan and section views is one of the best I came across.

Curious about other users experience & tips and tricks!

Cheers
Jiri
