node editor - pyflow

[Maarten]

Hello everyone,

I did some experiments with PyFlow Nodes with FreeCAD.

With new nodes using Python lists and made nodes for GIS2BIM in PyFlow based on Python Functions.

GIS2BIM is a collection of nodes I made for Dynamo a couple of years ago:
https://github.com/DutchSailor/GIS2BIM

The quality of the Pythoncode is unfortunately not on the level as you guys do it, I'm trying my best to reach your standard.

• Additional nodes: https://github.com/DutchSailor/FOSS-BIM ... /PyFactory
• GIS2BIM-nodes: https://github.com/DutchSailor/FOSS-BIM ... m/GIStoBIM
• Example PyFlowgraph: https://github.com/DutchSailor/FOSS-BIM ... %20GIS2Bim

Some problems:
• Couldn’t get the FreeCAD-nodes working in Pyflow.
• PythonNode within PyFlow is not working so I made the nodes editing the functionlibraries python file.
• Couldn't figure out how to make your own 'pinType' so a list is now a 'anyPin' type.

Some questions:
• I think that PyFlow can work for FreeCAD like Dynamo for Revit. A lot of users without coding experience can use it for automation. What is your vision on this?
• What do you think of using Python lists within Pyflow versus Numpy Arrays?

Please feel free to make any comments or if you think things should go in another direction.

Sorry for noob question

Could you add nodes for connect LibreOffice Calc and FreeCAD Spread Sheets?

Hi guys,

I am getting a error while I try to run "Create All Nodes for Test". Any ideas? It seems to be something related to 'FreeCAD_Toy3'.

how can I start using Pyflow WB por nodeditor?

Shoould i just download and copy to MOD folder in windows 10?

I installed it according to your README.md but I have some errors

this appear after use "create all nodes for test" and the PyFlow windows start a crazy bug, never stop trying to create a selection rectangle



should I install more dependencies?

Can this be a starting point for a node editor ?

Mr. @Mircroelly2 how did you install the MAYA nodes?



I did install all others except Maya node because, according to internet, is python 2.

[jtm2020hyo]

I hope can any dev can read this:



I need to request to create a fork for PyFlow for FreeCAD because microelly2 is MIA (missing in action) anywhere in their blog, discord group, or youtube.

actually, Pyflow is already usable, just a unique node does not load, Maya because python2, for other nodes, just is need install python modules (dependencies) to be usable, I think any developer could do this.

is very necessary to launch a stable Pyflow version because other devs than wish to create nodes for their software need a stable version for than their users can test.

here just is need a unique change if have time, and is than each node should contain their python modules (dependencies)

[looo]

I need to request to create a fork for PyFlow for FreeCAD because microelly2 is MIA (missing in action) anywhere in their blog, discord group, or youtube.

As far as I know @microelly2 used a fork of pyflow. There were some attempts to unify pyflow with his fork, but as far as I can remember this never happened.

I created a pyflow package for conda some time ago. version 2.0.2. I would like to work adding necessary patches to make pyflow compatible with freecad, and further adding the changes to the main repo.

You can start pyflow within freecad (assuming you have a working pyflow installed) with:

Code: Select all

from PyFlow.App import PyFlow
from Qt.QtWidgets import QApplication
instance = PyFlow.instance(software="FreeCAD")
instance.show()
