Got it working!
The script now outputs the 3D surface area for a selected compound path, along with some other useful data.
I verified the values are correct by exporting a DXF, & creating a 3D model in solidworks.
It would be nice to add a dialog so users can input a 3D Thickness value. Most of the time I need .25" thickness so hard coded is fine for now.
Here's the final code.. Enjoy!

This is probably my final update..
I added this updated Notice to the header of the script:
/* NOTICE: This tool only provides correct values when
the selection is either a single manifold shape, or a single
manifold compound shape, with no internal self-intersecting
geometry. Correct selection geometry will export to DXF,
import to solidworks & extrude to materialThickness as a
single body, with identical output for area & other values.

Thanks for the quick reply.
I tried adding your string to my alert output and all it returns is "undefined"
I also tried running it in a new script with no other fucntions. Still only returns "undefined"
Here's a screenshot of the alert output:
& heres my updated code.. Let me know if you can help me get this going!

Thanks for the reply.
The object is a compound path, vectors for a laser cut logo plate.
Adding this line broke the script:
' + 'selection[0].typename = ' + selection[0].typename + '\n' \
I am what is called extreme novice in javascript & I appreciate any additional guidance.
Thanks!

Ok, I see your file is not a single manifold component. The vectors intersect & so there are actually 2 manifold shapes here.
The script is only returning values for one of these shapes.
When I opened your file, I made zero changes & ran the script. The output values do appear incorrect...
Next, I created a compound shape using this method:
Select all & click the "Unite" button in the Pathfinder Pallet...
After using the "Unite" Command, I ran the script again & this time got the different output values. This time the values were correct, but only for one of the objects in the selection (the one on the upper left), since there are actually 2 shapes here.
The problem with this perticular part is that its not mainfold. If a laser were to follow these paths to cut a part from plate steel, you would end up with two parts (the upper left, & lower right.). For this script to work correctly, there must be only 1 single manifold compound shape that would produce only a single manifold 3d component when imported & Extruded in solidworks.
When I eliminated one of the objects and ran the script, the correct values are returned, as verified in solidworks.
In conculusion, this script only works on single manifold compound shapes with no internal self-intersecting lines that would result in multiple manifold objects in a real laser cutting situaion..
Enjoy!
