sdiviewer can not open .vue

[17710457586]

I compiled the .NET samples in the 2025 SDK. Why can't I open the .Vue model no matter I run SDIViewer alone or put it in the installation directory of Navisworks? However, I can open the .Vue model with Navisworks software.

Hi @17710457586 ,

I am able to reproduce the issue on my end.
It appears to be a limitation of the View Control or Document Control API, though I am not entirely certain.
I have raised the issue with the Navisworks Engineering team and will get back to you as soon as I receive their response.

Hi @17710457586 ,

It appears that the .NET Controls can only open NWD, NWC, and NWF files, and not third-party formats.
This behavior is by design.

However, I put SDI Viewer in the Navisworks Manage installation directory and it can open third-party formats such as .rvt .skp .rvm, but it can't open .vue format. It is not limited to .nwd .nwc .nwf formats.

This is the official description in .net docs

MultipleDocument	Multiple document application. Any number of DocumentControls may be created. A multiple document application supports a limited set of Navisworks APIs and Navisworks native file formats.
SingleDocument	Single document application. Only one DocumentControl may be created. A single document application supports the complete set of Navisworks APIs and file readers.

in sdiviewer the ApplicationType=ApplicationType.SingleDocument.So I don't think that net control does not support third-party file formats. The problem is more like not finding the relevant dependencies and therefore unable to load the corresponding loader?

First of all, installing anything in the Navisworks installation directory is not recommended.

Looks like, third-party file formats are not supported by the control, though it’s possible they may have worked in the past. However, this likely hasn’t been tested in many years, so if it ever did work, it is probably broken now.

One suggestion from the Engineering team is: “You can use the COM Automation API to convert the VUE file to NWD first.”
