Can we extract draft sheet as pdf of a sheet in ML workbench. i had tried using Pycelonis but didn't find any attributes related to extraction of pdf after analysis.draft.sheet

The question is not very clear are you trying to extract an analysis as PDF using ML Workbench ?

If yes I have not seen an API for the same but you can use a Skill or Action Flow to achieve this
