Problems reading a GLP from Alibrescript. Help!

[srjacob]

I am having problems reading from a GLP using Alibrescript. I thought I was reading a specific parameter, but I get the wrong values.

Please Help!

TIA.

Without your assembly and AlibreScript code it is impossible to see what if anything you are doing wrong. I have never used the global parameters with AlibreScript. If I'm using AlibreScript I usually just change the parameters directly in the assembly/parts with the script.

# open global parameters,path is D:\SJ Library\Projects\Pen holder, file is PenHolder
Params = GlobalParameters('D:\SJ Library\Projects\Pen holder', 'PenHolder')
# get access to a parameter and display the current value
TCFH = Params.GetParameter('TopCenterOfFirstHole')
print TCFH.Value

And the console value:

cls : Clears the screen
help : Shows the list of console commands
run : Executes the current script
run arg1 arg2 : Executes the current script, pass arguments
run "scriptname" : Executes a specific script
run "scriptname" arg1 arg2 : Executes a specific script, pass arguments

>>>
15.6845

That value is correct but in millimeters since you didn't specify Units.Current in your script.
Use these at the top of your script if you plan to do any math and to set the units to Inches.

from __future__ import division  # This fixes division with integers. For example the 1 / 2 = 0.5 instead of 0
Units.Current = UnitTypes.Inches

Thank you. That fixes the issue. I did not know the default units were in mm. I normally use mm, but in this case, I needed inches.

I shared this for that exact reason in your other forum post:

Looking for a script to change global equations

I am looking for a script to read and change global parameters. I am trying to make equations in either the equation editor or global equations, and the strong typing is making it impossible to build the equations correcctly. My only hope is to turn to AlibreScript to write a little program is...
