DELMIA Material Deposition Fabrication

Hello everyone, I am using the Material Deposition Fabrication app to generate Event Series (NC codes) for SIMULIA Additive Manufacturing Scenario to simulate the DED/Additive process. I was able to finalise the process on a simple wall without printing plate (build tray), but I want to add the build tray and there is no option to generate the Build_Tray or even i imported one and I can't fix the part on the build_tray,, anyone could help me in this issue? Is there any move command to place the part on build tray while considering the relevent axis? Thanks.
