Revit 2010 – Publishing Shared Coordinates and Using Named Views Across Linked Files

Software:  Autodesk Revit Architecture 2010

Description: In this video, we quickly talk about the role of model structure in linked file systems through the topic of shared coordinates.  We give an overview of rotating the project north, specifying coordinates at a point in plan, and also in elevation.  We then walk through how to, and what the effects are, of publishing coordinates.  Finally we introduce and explain the concept of ‘Named Views’ and how these work with our linked file structure.

Topics Covered:

• Host and Link file structure
• Overwriting host file’s internal coordinates and rotation
• Recording an instance’s location as ‘shared’
• Publishing
• Creating named views in the host file
• Viewing different named views in the link file
