Hello,
At this time the Autodesk BIM 360 Field is not supporting Multi-Sheet DWF format file for markup or viewing. If you have any feedback that you would like to submit regarding any enhancement, please click on the “Suggestion Box” link on bottom of the BIM Field 360 home page and submit your request to the project manager. This will help the PM and developers hear your voice on any changes/concerns with functionality directly for consideration in future builds.
Please, let me know if this help.
Thank you and have a great day!
Best regards,
Anil Mistry
