Get area in square feet independent of document units

[jcbarnes75]

I am trying to calculate the area of a 2D polygon in square feet, independent of whatever the document units are. The "area" node only returns a value in the document units. Is there a way to specify the units independent of the document settings?

Hello,

 

the function vs.GetUnits() returns a variable that tells how many units are one inch:

 

fraction, display, format, upi, name, squareName = vs.GetUnits()

 

You can create a node that returns this value. The rest should be straight forward.

 

regards,

Patrick

Thanks Patrick. Let me backup. How do I create a node that returns the vs.GetUnits variable?

You don't have to create a new node from nothing.

I simply hijacked the any-node. 

@Marionette.NodeDefinition
class Params(metaclass = Marionette.OrderedClass):
	this = Marionette.Node( 'UnitsPerInch' )
	v = Marionette.PortOut()
	v.SetDescription('The resulting value')

def RunNode(self):
	fraction, display, format, upi, name, squareName = vs.GetUnits() 
	
	self.Params.v.value = upi

Ah, I was just starting to do that. Thanks for your help.
