[chari]

Hi, I would like to ask for help. I am getting problem with exporting point cloud. I am able to export - model, orthophoto..but if I try to export point cloud I get a message - Can't write points...Has anybody seen it before? Thanks.

I just started encountering this issue also with the new update. successfully exported a couple point clouds but am stuck on one of my projects. can't seem to reproduce the issue reliably yet...

Hello,

The issue will be fixed in the next update.

Currently you need to extend the bounding box prior export to avoid the problem.

Hi,
Using the Python API, I also found, exported point clouds in laz,ply are everytime corrupt due to the "cant write".

Hi Alexey,
thanks for advice. It worked out after I extended the bounding box.

Hello Ruedi,

You needd to use same workaround and extend the bounding box, for example, like following:

Code: [Select]

new_region = chunk.region
new_region.size = new_region.size * 1.1
chunk.region = new_region
chunk.exportPoints....

Hi,
I have a problem when trying to export my project as an LAS or E57 file. The following error occurs: 'Can't write file'.

I have plenty of space on my different drives. I have tried to export to C drive and other drives.
I have tried to erase bigger parts of my project, and then suddenly it works. When I then try to find the exact part of the project that generates the error by erasing small parts a the time, it still doesnt work.

I have to hand in the project to the client to day! 

My project has 3 other chunks that works just fine!
PLEASE HEEEEELP !

Did you try splitting it up in blocks of 1km while exporting in the export menu?

Hello jbd@tvilum.dk,

Same workaround for you, if you are using 1.2.1:
extend the bounding box prior exporting to avoid the problem.

[jbd@tvilum.dk]

What do you mean extend the bounding box?

Do i just have to manually resize the region a little bit bigger?
Yehaaaa.... I seemed to work just resizing a little bit! THANKS A LOT!!!!

MERRY CHRISTMASS GUYS AND GIRLS!

[Alexey Pasumansky]

Yes, manually (or via scripting) resize the working region.

The issue will be fixed in the next update, sorry for the inconvenience.

When we try to export the dense point cloud, we take the next message:
"Can´t write points C:/...."

[miami4quad]

The sparse point cloud will export without an error. No matter which quality dense point cloud i try to export in any format, or coordinate system i get a "cannot write points" error. Agisoft version 1.2.1 any ideas?

Thanks
John

For now, you can use "Resize Region" and increase the size of the bounding box just a bit, (exact amount not important). I found you have to drag opposite corners so the entire box is increased, see image

This will be fixed in the next version according another thread on the forum.
