We received the schematic model on Revit by the team was working on it. we set a meeting with Eng/ Hadeer Alaa, the responsible engineer for this project, we divide the work between us (me and Another Trainee Hala Alaa) to convert these drawings to working drawings that could be submitted as Permits.We worked on a central file ''BIM ''with the Help of Eng/ Hadeer Alaa. It allows more than one user to make changes to the central file by editing local files and synchronizing those changes with the central file.
