It looks good to me! Some minor things in the .htm file:
The <link rel="stylesheet" href="moi://ui/moi.css" type="text/css"> can be removed, it isn't needed anymore starting with MoI version 3. Same with xmlns:moi in the <html>.
In the <head> you can put in a <style> with some style rules and then all the individual inline style="" and align="" attributes can be removed, see attached.

Hi Michael,
Thank you very much for pointing out the `.htm` documentation. I'll definitely take a look at it later.
For now, I think I may have found a bug related to the bounding box dimensions.
I wrote this simple script to retrieve the bounding box of the selected object(s). However, when I displayed the values using `moi.ui.alert()`, the reported dimensions did not match the X/Y/Z size shown in the Object Info panel.
Here is the script:
code:
function excercise_06()
{
var rnd = moi.geometryDatabase.getSelectedObjects();
var bbox = rnd.getBoundingBox();
moi.ui.alert(
'X Length : ' + bbox.xLength +
'Y Length : ' + bbox.yLength +
'Z Length : ' + bbox.zLength
);
}
excercise_06();
In the screenshot below, you can see that the X dimension reported by `bbox.xLength` differs from the X Size shown in the Object Info panel.
Am I misunderstanding what `getBoundingBox()` returns, or could this be a bug? I've attached the 'problematic' 3dm file.
Thank you very much in advance for your attention.

Hi Elang, since getting a precise minimal bounding box can be a time consuming calculation there are various types of approximations.
The one in the object info panel is based off of the display mesh. If you click on it to open the "Edit size" menu it will do a more accurate solver based calculation in the menu.
The one used by ObjectList.getBoundingBox() is quick to calculate and uses the bounds of surface control points. It can be larger than the accurate bounding box.
Do this if you want a "tight" bounding box:
code:
function excercise_06()
{
var rnd = moi.geometryDatabase.getSelectedObjects();
var bbox = rnd.getHighAccuracyBoundingBox();
moi.ui.alert(
'X Length : ' + moi.ui.formatCoordinate(bbox.xLength) +
' Y Length : ' + moi.ui.formatCoordinate(bbox.yLength) +
' Z Length : ' + moi.ui.formatCoordinate(bbox.zLength)
);
}
excercise_06();

Understood... Thank you very much, Michael!
