Hi Nemoz,

It's moi.geometryDatabase.getSelectedObjects().

If that is not working for your script, please post the script and .3DM file, or send it to me at moi@moi3d.com so I can try to reproduce the problem over here.

For getting a bounding box:
var bbox = obj.getBoundingBox( true /* Use high accuracy bounds */ );

Bounding box has these properties:

bbox.min
bbox.max
bbox.center
bbox.xLength
bbox.yLength
bbox.zLength
bbox.diagonalLength


Calculating surface area:

function GetObjectArea( objects )
{
	moi.geometryDatabase.deselectAll();
	objects.setProperty( 'selected', true );

	var area = moi.ui.propertiesPanel.calcSurfaceArea();
	moi.geometryDatabase.deselectAll();

	return area;
}

Calculating volume:

function GetObjectVolume( objects )
{
	moi.geometryDatabase.deselectAll();
	objects.setProperty( 'selected', true );

	var volume = moi.ui.propertiesPanel.calcSolidVolume();
	moi.geometryDatabase.deselectAll();


	return volume;
}

So ... a lot of coding and finally I'm very close to the end... Attached you can find the manual, 2 axes operations already tested and even lathe operations and 3 axes operations, now I will start the testing for 4 axes operations... 5 axes operations can't be tested because I don't have yet a 5 axes machine, I can only import in a gcode 5 axes simulator . As soon as I will be sure that everything is done I will release it.

It looks like an epic piece of work.
I'm looking forward to testing this with my PlanetCNC controlled lathe.
Thanks for the all the effort you must have put into it.

are you using windows based pc?

Yes. I'm staying with Windows 10 for as long as posible. ;-)

I don't want to know which cam you are using actually, but can you spot a postprocessor in that list that fit your machine? I used this type of postprocessors because this is the biggest postprocessor library downloadable for free.

We can even make one from zero in case... I'm finishing the GUI to create post processors...

I have a Mach 3 controlled milling machine as well as a PlanetCNC lathe, both of these use a very similar g-code structure which is mostly interchangeable. The PlanetCNC controller can use g-code written for a LinuxCNC machine, so there is nothing unusual to allow for there.

Wow amazing a long time RHINO CAM paired with a SHOPBOT PRS5 with 5th axis on windows 10 been solid for nearly 20 years,
Look forward to the release and costings?

I'm traveling in Asia, beta 1 is available... every key will last for 30 days, I will release a newer version before 30 days, I will create a discord channel for bugs and future developments. For sure there are some bugs, beginning of 2026 I will have time to fix them and to check everything in detail. Actually the files from some operations are already tested and used in production on 2 Doosan Puma 2100 and one Haas 3 axis.

I'd like to try this plugin, but I'm getting download warnings and the email confirmation went straight to spam, so I'll wait until something changes before dipping my toe into the water.

Thanks.
Martin.
