Class Object

[Peter__B]

Hello

Part of my python code contains the following:

class ParameterChange:

      def __init__(self,dia, length):

           self.DIA = dia

           self.LENGTH = length

If I execute it and also run e.g.

param = ParameterChange(1.1,2.2), I will get for param.DIA...1.1 but python says that param.LENGTH does not exist. Just the first works.

In standard python it works but not in the Spyder version in fusion 360.

Does anybody know why ?

Best Regards

Peter

Hello,

the following script works as expected:

import adsk.core, traceback

class ParameterChange:

      def __init__(self,dia, length):

           self.DIA = dia
           self.LENGTH = length

def run(context):
    ui = None
    try:
        app = adsk.core.Application.get()
        ui  = app.userInterface

        param = ParameterChange(1.1,2.2)

        ui.messageBox('{} , {}'.format(param.DIA, param.LENGTH))

    except:
        if ui:
            ui.messageBox('Failed:\n{}'.format(traceback.format_exc()))

Is it necessary to have all statements e.g. in the run function ? or can I have them outside to ? perhaps it special for "python Spyder fusion script" ?

In short, no. You can write your code outside the "run" method but you need to hook into "events" to do so - see this help topic.

I write my add-ins like proper python with objects, modules, packages, the whole bit. See this post for my boiler plate code which uses some black magic to abstract away the irritating "event object instance" pains.
