v8 is very old, and unsupported by many newer extensions, but CofG should work with it...
It appears the '.round()' function isn't working...
I don't have that version installed to test it...
I can't find an earlier version with the round code in it...
You could try editing the RB file with Notepad++ so the
lines#379 to #390, which read
becomes this edited version to avoid any arguments for the round method.
#dp=4 #volume=0 ### ### convert it to units matching density... #while volume == 0 volume=(vol * 0.000016387064).round if @units=~/\/m3/ volume=(vol * 16.387064).round if @units=~/\/cm3/ volume=(vol * 0.000021433471).round if @units=~/\/yd3/ volume=(vol * 0.000578703704).round if @units=~/\/ft3/ #dp+=1 #end #dp-=1restart SketchUp and see if that helps...
