It would be great if we could model a 3-axis mill spindle and be able to attach it to the tools in the tool library so we can check for clearance issues when running simulation. But not make it like the "add a new holder" option but to be able to create the spindle completely as a model then create coordinate system at which the tool holder would align itself to the axis defined an then open said model in the library. We can name the coordinate system a specific name so the program knows to attach it so when there's multiple coords it wont get confused. I prefer adding my mill table with vises and OTC into the CAM so i know nothing will hit.
