Casting Goo to KUKA|prc Command

[MkMrA2]

I need to use GH Python (Python 3 Script) to properly sequence a set of KUKA|prc Commands.

I'm taking input from the PRC components Digital Output, LINear Movement and Wait commands. These are generated by those native Kuka PRC components.

The python is just taking those lists and building a new list with them sequenced as I need. (It's much easier for me in Python than native Grasshopper!)

It builds the list no problem, but when I try to use it as input to the Kuka CORE, I get the error "1. Data conversion failed from Goo to KUKA|prc Command".

So, in Python I need to cast this so it's in the appropriate format.

How do I do that?

Thanks very much for any help!

Hello Mark,

I use Python from time to time e.g. in Blender or Fusion, but honestly never properly used it within Rhino.
Can you make a very "slim" example that I could debug? Note that I'm officially out of the office next week, so it might take a bit longer than usual...

Best,
Johannes

Attached is a simple example. Three Kuka PRC Commands get wired into a python node.

One test just assigns them to a list and outputs them. The other casts them to KUKAprcCore.PRC_Classes.PRC_CommandData and outputs them.

Neither can be used as input to the CMDS input of the Kuka Core.

I don't know how to make them into a known, valid type.

Thanks,
Mark

Hello Mark,

Instead of

Code Select Expand

KUKAprcCore.PRC_Classes.PRC_CommandData use

Code Select Expand

KUKAprcGH.PRC_IOClasses.GH_PRC_CommandData.
The second one is the class that extends GH_Goo and contains PRC_CommandData.

I tested it briefly and it worked for me! You will also need to import the KUKAprcGH namespace on top.
Best,
Johannes

Hi Johannes,

Thanks for answering questions while you are away!

The suggested fix works great. I appreciate it!
