But I'm sure I can't be the only one experiencing this problem. Not the most interesting post by any stretch and if you're still reading now, thanks. svf file output and ensuring everything is coming through in the view. I guessing I'm at a place where what I'm really after is a custom Forge viewer application to design in the functionality I am after, in this case control of phasing in the.

In the "3D" 3D view I have created everything is phased correctly, no issues from worksets, visibility graphics, view discipline is coordination (doesnt work to change to mechanical) and everything looks hunky dory in Revit. Most notably it's missing ducts, sanitary pipework, cable trays, radiators. However, I am only getting some elements from the services model come through into the Autodesk Viewer application.

Could this also have been better solved by setting generateMasterViews to true during the POST job on a custom Forge viewer app?.I managed to get around this by creating a 3D view in each model just called "3D" and setting the phase and filter as I like. Initially I uploaded our services model with supporting architectural and structural models but the phase the solitary 3D view created in the viewer was "Existing" with a filter of "Show All". Unfortunately though, I have encountered a couple of problems, one of which I think I have solved and one which I am guessing is more to do with the Autodesk Viewer Applications programmed interaction with the model derivative API. I've been trying to encourage some of our less Revit-savvy building services engineers to utilise the Autodesk Viewer product.
