Tool Assembly creation

Hi ! 

I'm creating my first program for a Linux CNC mill using DELMIA NC Shop Floor but can't assign tools because the tool assembly is empty. I don't have access to the DELMIA Cutting Tool Builder app in my 3DEXPERIENCE account. I have the SolidWorks for makers subscription. How can I create or edit tool assemblies without it?

 

I found a custom post-processor for Linux CNC and successfully added a machine with it. I also managed to add tools created during the setup of my manufacturing cell to the Configuration Tool in Resource Configuration View. However, when I try to "assign" the tool, I receive a message telling me to select an axis system on the work area. So I can't create machinable features.  

 

I must be missing something. If anyone has an idea about it, it would be a huge help.
