def function inside the main python script

halitomi — Sat, 09 Apr 2022 12:39:16 GMT

I would like to use an "inner" function in python multiple times to create a more advanced script where I do not need to use the same lines over and over again. But it seems anything created in the "inner" function does not exist in the main, outer script. Is there any solution for this?

A very simple example here:

from varmain.primitiv import * from varmain.custom import * from math import * @activate(Group="Support", TooltipShort="Class1", TooltipLong="Class1", LengthUnit="mm", Ports="1") @group("MainDimensions") @param(D=LENGTH, TooltipLong="length of box") def Class1(s,D=50.0,**kw): def Inner(): o1=BOX(s,L=D,H=D,W=D) return o1 Inner() #up to this line the scripts runs smoothly, the box is generated by the "Inner" function with sides "D" o1.translate((0,10,0)) #this translate generates and error because "o1" object seems to be not existing outside the inner function s.setPoint((0,0,0),(1,0,0))

Dear @halitomi ,

A question about your script structure where did you get this information?

I am not sure if this answers your question:

I have tested the script both with the translate function and without it. Without it, there is no error.

Also any other command which “needs” o1 generates an error if the command is outside the inner function.

Yes this will also happen in the future.
Attached is the tutorial for scripting in Plant 3D with Python.

I know this document. It is just strange that I can not use the “def” function here, as far as I understand it is basic python stuff.

You can define multiple functions in a single file, they just need to be outside of each other (I haven't tested nested), I did that before (multiple separate functions) when I needed the user to be able to select different beam geometry in a support in the objects properties in plant, external function would do a very simple lookup and generate/return the created beam geometry that got stored in a main function variable.

wow, thanks George!

maybe I am asking too much here:

But would you share a sample script using multiple defs? (just a simple one where one is making a box while the other a cylinder or something like that, I do not need the actual big one)

It's easier than that, I'm sure you've decompiled the .pyc files in the variants.zip file, after you've decompiled those have a look through them, there's plenty in there with examples of it and examples of how to do just about everything.

Change it to the following. It should be OK.

from varmain.primitiv import * from varmain.custom import * from math import * def Inner(): o1=BOX(s,L=D,H=D,W=D) return o1 @activate(Group="Support", TooltipShort="Class1", TooltipLong="Class1", LengthUnit="mm", Ports="1") @group("MainDimensions") @param(D=LENGTH, TooltipLong="length of box") def Class1(s,D=50.0,**kw): o1=Inner().translate((0,10,0)) s.setPoint((0,0,0),(1,0,0))

I am having an issue in calling other script into main script. I have two. First is the modelling script and second is the one that calls first for geometry creation. Everything works fine and geometry is createdbut I cannot rotate or translate or subtract/unite the geometry created this way.

First script (Modeller.py)

from varmain.primitiv import *

from varmain.custom import *

from math import *

def strBeam(s, L=25, W=25, H=1000):

->s1= BOX(s, L=L, W=W, H=H). translate ((H/2, 0, W/2)) # create and move box on positive XZ

Main Script (TestBeam.py)

from varmain.primitiv import *

from varmain.custom import *

from math import *

import os
import sys
scriptpath =os.path.normpath(sys.PnP3dNativeContentCustomScriptsPath)

if scriptpath not in sys.path:

->sys.path.append(scriptpath)

from Modeller import *

@Anonymous(Group="Sleeve", TooltipShort="Straight Beam", TooltipLong="Straight Beam", LengthUnit="mm", Ports="2")

@group("MainDimensions")

@Anonymous(LN=LENGTH, TooltipShort="length", TooltipLong="length")

@Anonymous(WI=LENGTH, TooltipShort="width", TooltipLong="width")

@Anonymous(HI=LENGTH, TooltipShort="height", TooltipLong="height")

@group(Name="meaningless enum")

@enum(1, "Align X")

@enum(2, "Align Y")

@enum(3, "Align Z")

def TestBeam(s, LN=2000.0, WI=50.0, HI=50.0, ID="TestBeam", **kw):

->beam1 = strBeam(s, s, L=WI, W=HI, H=LN) #line1

->beam1.translate((50,50,50)) #line2 random move

->beam1.rotateZ(90.0) #line3 random rotate

-> mark is to show proper indentation here

So when I compile and test run TestBeam script. It successfully calls the Modeller.py and uses strBeam to create a box (i.e. if the code termibate at line1). But if I try to move or rotate it (i.e. if the code also has either line2 or line3), geometry failed to create and I am thrown an error 'geometry cannot be created wuth given parameter.nil'

So any help guys??

It looks like you have an extra parameter when you are creating beam1

Oh thats just typo error here. In the code its not there and like i said that geometry is created perfectly but I cannot perform any actions on it like translate, rotate, unite, subtract etc. That's what i need

I have same error with you. Successful call shade after that can't move or rotate.
Anyone have solution ?

You simply need to add a ‘return’ value at the end of the function. Without that the function only creates geometry but main function cannot play with it. If you return it with a value then the holding variable in the main function can play around with it
