About the Dino script
<< This script works by exporting the selected solid to an STL file and then loads it back and calculates the volume from the STL data.

Where I load it back ? In Moi there is not Import STL ! ???

Thanks Max! Really appreciated. :-)

I was looking for an efficient way calculate volume and hit upon this http://stackoverflow.com/questions/6518404/how-do-i-calculate-the-volume-of-an-object-stored-in-stl-files

Really nice ideas, BTW!
I think that using obj is a good solution and it can improve things a lot. Also, materials!

I'll be away from my computer until monday night, but in the meantime feel free to improve this script any way you like!
I really like the idea of the mini open source scripts that are created on this forum by 2 or more people. That was the case with the LightOptions script. It was Mike's idea and helped a lot during its development. Then you included it in your UI and it was improved once again.
Cool stuff.

Hi Dinos, re:

> That can be easily fixed if there is a way to set the STL export options to Ascii
> during export, but nothing that i tried worked.

That should be something like:

var OldSTLExportType = moi.settings.stlExportFileType;
moi.settings.stlExportFileType = 'Ascii';


<....>


// Reset original STL export type when finished.
moi.settings.stlExportFileType = OldSTLExportType;

Updated version of Dinos's CVolume.
Now it uses obj file. Performance boost +50~100%
Defaut angle = 3. You can use command line parameter to change it. Example: _CVolume 10 or _CVolume 1

How it works ? Inside Moi ? You import an OBJ file ?

Ok , I have found the method : Now 1 second on my computer! :)

But same time and result when adding a number! (little or big)
1685.156253 When importing an OBJ

With the normal file
1688,220446 in 2 seconds by default _Cvolume

1668, 250237 in 1 Second with _Cvolume 10

1561,334244 in 0 second with _Cvolume 100

Pilou, forget about obj :)
It's internal script mechanics. The script exports solids to an obj-file, then loads them back as polygonal model, and calculates volume.

P.S. I have great ideas about this script. ;))

Yet existing is now some speedy : just maybe the precision can be improved a little! :)

The script requires running MoI with elevated privileges to work in Windows default installs. If you can look at how you are writing the objects to avoid that would be good.

Hi BurrMan
new version of the script will use system temp dir instead of moi dir.

CVolume v.0.98

Added: User interface, densities of miscellaneous materials etc.
Changed: temporary directory

In the next version I'll add tool for a model resizing by adjusting mass or volume.

P.S. Click to "Volume" or "Mass" label to copy value to clipboard.

Excellent Max.

I don't know how far you want to take this, but if you had the option to input the cost per unit of the material, the script could display the value of the object. Great for jewelers or folks who have their design 3D printed in metal.

Or pull the material cost in from an XML file, if such a file exists in the folder. Possibilities here for the user to update their material cost XML file off the web, using a script outside MoI of course, to pull in the current price of precious metals.

Taking a step further, associate the material cost XML file with a MoI style. Assign a "silver" Style to a ring, you get the material cost if it's cast in silver (not including waste of course). Assign a "18k gold" Style to a ring, you get the material cost if it's cast in gold.

Just some far out ideas ...

Aaaaaaaaah! What a such list to translate! :)

PS I have put _cvolume 0 : that gives the good result with 2 decimal! 1688, 42 (takes just 26 seconds on my computer ;)
The other values goes very more speedy! :)
_cvolume 2 1688, 34 in 3 seconds
_cvolume 3 1688, 22 in 2 seconds
_cvolume 4 1688, 06 in 1 second
_cvolume 5 1687, 84 in 0 second

_Cvolume Alone is like _cvolume 3 : 1688, 22 in 2 seconds

Version 1.0

Improved interface.
Added mass and volume adjustments. Great feature! I like it :)

Click to "Volume" label -> Copy volume value to clipboard
Click to "Mass" label -> Copy mass value to clipboard
Double click to "Volume/Mass Calc." label -> Restore original volume

Hi Max,
I really love what you've done to the volume script :-)

Just one request:
in my original version i was converting cubic mm to cubic cm as this is a lot more meaningful, especially when dealing with 3D printing.
Can you add that feature back? As far as i know no one deals with cubic mm..

Other than that, excellent work :-)
