Large point clouds in V5

[Alan Lowbands]

Hi,

Can anyone please tell me how I can extract or select the individual points from a large point cloud imported into catia v5.
I just get the message " too many points " when I try.

any help would be really appreciated,

regards
Alan

Did the import worked or you got too many point during import?

Hi itsmyjob
The import worked fine and you can see all the points.
As there all in one item in the geo set I can select one point without it selecting them all.
On smaller clouds Iv been able to extract the actual points but this is saying there are too many.
Unfortunately it’s massive and I can’t split it up smaller clouds

you need some license you work with cloud of point. what license you have?

when you imported the points it gave a report about the number of point?

They were imported from an .asc file in digitised shape editor.
This has imported the cloud as group.
Usually if I select the group of points and use the cloud/points command it creates a new geometric set with each point inside.
This cloud I have has over 200k points and the command says “too many points”.
I’m looking for a way I can either extract them all or just the ones I need.
Unfortunately I can’t get another scan and need to some how use this one.

can't you operate on the imported point cloud from DSE workbench? (split and such)

Hi
Thanks for the replies.

I can't get it to do anything at the moment,
I'm not really used to DSE so trying to fathom it out.

I been told there's a limit to the number of points that the Cloud/Points function will work on of 10K.
This Cloud is silly big so I think I might be out of luck extracting the info I need from this with V5

using DSE you can filter the cloud of point, reducing the number then if needed you can use cloud/point command.

Can you create new points that reference the existing ones, point-on-point? Then extract the information from the new points?

 

[Alan Lowbands]

Hi All,

I've managed to get what I needed using the wireFrame commands.
I think that's what you might be saying 3DDave ?
Didn't know that you could do that and I'm really not clued up on DSE.

Many thanks for the help

cheers

so you buy a function and dont learn about it? you could have saved days to get your result if you knew how to use DSE

I didn't buy the license, it's on the company box im using but totally get your point.
DSE isnt something I've really need to use up to now but will get to know it better after this.

thanks again for the help

Alan
