Volume measurement explain

[Safia]

Hello,

Is Volume measurement measures the boundary box volume or the volume of the object?

thanks.

Best Regards,

Hi Safia,

the volume measurement is the volume of the object. You can see the mesh of the volume, and you-ll notice holes have to be filled in order to compute its volume.

Hi Andrea,

Thanks so much for your fast reply,

in the mesh volume i get not all holes are filled,

and when i choose mesh fill-selective it tells me that no holes are found. and watertight mesh filter not working.

Hi Safia,

it's hard to understand without looking at the dataset. If the subject is hollow (e.g. you're taking images from inside a room) then you need to use the hollow volume function.

Any chance you can share screenshots of the issues or , even better, images and zep ?

[Safia]

Hello Andrea,

no not hollow, the problem the volume measurement fills just some of the holes

please find attached a screenshot, thanks

Hi Safia,

you need to have the visibility of the full surface. Those gaps won't be covered by the fill holes in a way you expect. You can try using the project volume tool but you will likely get something not very useful. Unfortunately you need more images.

Hi Andrea,

I used volume / projection and it fills all voids and gabs not so accurately but with the data given it calculated and closed the volume, thanks

[Andrea Alessi]

Unfortunately it closes them as best as it can. You need more photos of the terrain in order to provide a full reconstruction.

[Safia]

Yes, right i know that, but this gave me an approximate result that I can after that modify on it.

Thanks

Hi Andrea,

Please I want to ask about what's the difference between mesh volume from
Mesh - - - - - - properties - - - - - volume

and volume get from measure volume

Both are different

And when I export the report he just export the voleme of mesh not the volume I calculated

Hi Safia,

there is actually a bug currently. If you calculate a mesh and check the properties of another object (e.g. if you have mesh1 and mesh2 and compute the volume of mesh2 then check the properties of mesh1) you may see the latest object volume in the info panel as well. You should check the volume of the unstructured mesh to be sure. We are fixing it in the next release!

I'll check for the report as well - it should show the values correctly if you computed them but there may be a connected bug, thanks for letting us know!

Hi Andrea,

In this case, I've only one mesh (Mesh 1) when I calculate the volume by projection it creates another mesh (mesh 1 volume unstructured) .

Mesh 1 volume 14750 (from properties)
After I exported the report I found that mesh 1 has volume 17050 (from properties)

The report in volume measurements list
Mesh 1 to be 17050
Mesh 1 volume unstructured to be N/A

???

Hi Safia,

as i mentioned we are correcting bugs to volume display.

I can send you a key for our current beta testing of the upcoming version if you'd like

Hi Andrea,

Thanks so much, I will wait the next version. Thanks again ?
