Hi folks, is there any way to find the height of the current figure in poser units with a python script? any ideas?

Poser 11 Pro, which everyone should have by now, has measurement tools built it. I recall that these are geared to the crowd who use Poser for forensic crime-scene reconstruction and medical uses. Thus there may well be such tools built in to Poser - you might usefully check the manual on that before writing a new script.

That doesn't help.

A script has no possibility to create a measurement prop. Nor to access one to measure something.

Here is somethin that works:

import numpy as np

poserfactor = 0.0038145

figure = poser.Scene().CurrentFigure()
scale = figure.RootActor().ParameterByCode(poser.kParmCodeASCALE).Value()
geom, _, _ = figure.UnimeshInfo()
verts = np.array([[v.X(), v.Y(), v.Z()] for v in geom.Vertices()])
height = (np.max(verts[:, 1]) - np.min(verts[:, 1])) * scale / poserfactor
print("Figure height: {:0.2f} Centimeters".format(height))

Maybe you want to deal with the fact that scale is done on actor-basis (e.g. shorter legs). It can go really complicated If you need 100% exact values under all cirumstances. Think of a figure where parts are scaled via morphs for sick people with a bended spine.

I got the "poserfactor" this way:

Go to General Preferences -> Interface and set Units to what you like to measure (I used "Centimeters"). Close preferences. Dial "1" into "yTran". Go back to preferences and set Units to PNU (poser native units). yTrans should now show you a value to use for division (maybe you have to dial any other one to wake up Poser and make him show the changed value).

Or, look up the web or the forum. I bet someone did a list with all possible numbers :)

Thank you Adp001. I was thinking about measuring according to the type of figure, but I think your approach is better In the figures with size morphs we can check the values of Y Scales

Y Scale will not help if I let the scales for all bones alone and shorten the figures leg with a morph (remember, from P11 on we can set the joint centers accordingly to make such a change work).

Another problem with this type of measurment: Make your figure sit or laying on the floor...

class getunits:
    def analyze ( self , event = None ):
        units, uDisplay = self.unitCalc()
        cType = (u'PNU',u'in',u'ft',u'mm',u'cm',u'm')[['PNU','Inches','Feet','MM','CM','Metres'].index(units)]
        convert  = self.ConvertToPNU(1.0, cType)
        return units

    def unitCalc( self, event = None ):
        prefs=os.path.join(poser.PrefsLocation(),'poser.ini')
        if os.path.exists(prefs):
            pref=open(prefs,'rb').readlines()
            for line in pref:
                if line.lower().startswith('unit'):
                    line = line.split(' ')
                    if 'FACTOR' in str(line[0]):
                        units = float((line)[1])
        uDisplay, pType = float(self.response(units)[1]) , self.response(units)[0] 
        return pType, uDisplay

    def ConvertToPNU( self, value = 1, unit = '' ):
        multiplier = (1.0, 103.2, 8.6, 2621.28, 262.128, 2.62128)[[u'PNU', u'in', u'ft', u'mm', u'cm', u'm'].index(unit)]
        return value * multiplier

getunits = getunits()
analyze = getunits.analyze()

print analyze

get your own units or convert them using this script ( will need a little modification for purpose).
