Hi,I’m afraid just saying the lists come out blank doesn’t give us anything to work with. Please describe what you are doing properly so we can see if there is anything incorrect. Also it will likely help if you send us the model.It goes without saying that the model must be fully numbered including assemblies. I assume this is done as you say you have drawings but you should double check.Then try purging and auditing your model to fix up any dodgy data.
