Mabe I have missed it, but is there limitation to the ImportPointFile script such as number of points etc.? I downloded a sample .xyz file, but I am un able to open it with script. It does not error out, but simply does nothing.

Any clues?

Hi Michael T,

No, I don't think it has any limits for the number of points.

But it does need the points to be in a particular format - one point per line of the file with one separating character between each coordinate.

You also may need to open up the file in a text editor to see what the separating character is - you have to tell the ImportPointFile command what that character is in order for it to work correctly. That's the delimiter option that shows up for that command.

If the script runs into an error, it will just do nothing.

Can you please post the .xyz file here so I can take a look at it? It may have its contents arranged in some way that the script does not know how to deal with. If that's the case I may be able to modify the script to make it work.

Sure Michael G.

I have attached the original zip download.

I did open it in Word Pad and it appeared to use spaces for the delimiter.

Thanks,

Hi Michael T, thanks for posting the file.

So it appears that although there is no specific numeric limit, the ImportPointFile command is kind of slow to handle things because the script interacts a bit with MoI as every point is created. That's fine when there are a couple of hundred points but it bogs down quite a bit when there are 100,000 points like you've got in your file there.

It does seem to be loading the file though, just at a slow pace - I think that probably if you let it sit for an hour or so it will probably finish eventually. Note that it won't give any indication of progress during that time.

The speed of this import could be improved in the future, but I'm not sure what you would do with those 100,000 points inside of MoI though anyway?

True to your last statement Michael G.!

I was just running MoI through the paces :-)

I may try letting it run later, and I'll let you know the outcome.

Thanks,

Michael T.

Looks pretty good "as is". lol

What the!!
I've used point cloud data before but this is extreme.

Cheers

Hey Danny,
Actually, Rhino makes pretty quick work of this, though I just lost all my saves to save the result out....

Importing this cloud in Rhino you have the option to bring it in as a special entity type "as one", which opens it really quick.. Then it has a section tool to work it pretty quick.. I havnt explored it fully to see if it is more automated than a single plane at a time, but even a single plane at a time I could have a surface in about an hour...

I'm fooling around with a result in MoI right now using ConnectPoints, but I have to do it plane by plane and each calc takes a few minutes to complete...

I've got about 1/18th of the house done so far.. I will have to use rebuild on the resulting curve after I get them... The curve through points would be nice to automate on a plane type selection of points. Or if the ImportPoints script was more robust in it's curve creation to set a "plane direction" to get a desired result..

Anyway, I'll post if I get anything that looks somewhat acceptable.

Maybe using voxels in this case will be more speedy ;)

3DC will read a point cloud???

I don't remember but there is maybe a format import compatible?

I think it's a case of getting the points to poly's first, then 3dc will do a good job with it... I dont think 3dc will read points... I asked them awhile back to read DICOM files also, and got no response... If they did this, it could be a huge avenue for them...

Yep BurrMan, that's what it's supposed to look like according to the website.

Imported into MoI somewhere under 30 minutes:

Hi Michael T.

So last night I did about this much:



Which allows me to loft it. I'm looking at different settings to get a good loft, without loosing detail, though not trying to create the irregularities of the point conversion.

That looks great so far BurrMan!

@Bur : have you any problem to import files from Moi in Powershape? Have you add some plugins inside?
Because
3dm fail
Iges partial fail
Sat Fail

Message error speak about an Exange pluging ?
This one is not included in the program?

Hi Frenchy,
The file imports OK to Powershape.



"Exchange" is the translator program Powershape-e uses. It is a seperate download. It will show up on the welcome menu in Powershape and is free to download and use. It is also their system for creating "Vouchers" that will be used if you want to pay for your model "Translation out" of Powershape...

Be sure to download and install both programs to use it properley (Latest versions).

Go to "View/toolbars/explorer" and clcik on the browser tab in the explorer window.

Note: You dont have to open and use exchange, it just needs to be installed. Then Powershape will use it when doing imports of different formats.

Thx for the infos !

@ BUR: Works fine !
It's funny to load something more of 100 megas for a translator ;) But That works fine now for 3dm format! ;)
It's cool for see if something is wrong on a volume / surface !
