PyRx, Python template for AutoCAD

 

Arx users will immediately recognize this layout as it’s similar to AcRxArxApp, I actually considered making the entry point a class in Python, but it seemed overkill at the time.

After running the command ‘pyload’ or ‘pyreload’ to load your module, OnPyInitApp and OnPyLoadDwg are called, functions that are prefixed with PyRxCmd_ are registered as commands, functions that are prefixed as PyRxLisp_ are registered as lisp callable functions. Note, this only the file that is being loaded is parsed, imports are not parsed.

When registering and command with PyRxCmd_ the group name is the module name, the global name and local name are the same. Command flags are optional, with the default being ACRX_CMD_MODAL. These flags may be OR’d. I may wrap acedRegCmds->addCommand at some point, but the design intent is to be simple.

 

#import

import PyRx as Rx

import PyGe as Ge

import PyAp as Ap

import traceback

#optional called when the app is loaded

def OnPyInitApp():

    print("\nOnPyInitApp")

#optional called when the app is inloaded

def OnPyUnloadApp():

   print("\nOnPyUnloadApp")

#optional called when a drawing is opened

def OnPyLoadDwg():

   print("\nOnPyLoadDwg")

#optional called when a drawing is closed

def OnPyUnloadDwg():

   print("\nOnPyUnloadDwg")

   

# prefix PyRxCmd_ defines a command

# CmdFlags is optional, default is modal

def PyRxCmd_mycommand(CmdFlags = Ap.CmdFlags.TRANSPARENT):

    try:

        print("Hello world!")

    except Exception as err:

        traceback.print_exception(err)

# prefix PyRxLisp_ defines a lisp function

# (mylisp '("hello world" 1 2 3 4 (1 10 100)))

def PyRxLisp_mylisp(args):

    try:

        return args

    except Exception as err:

        print(err)
