Autodesk viewer - Lack of data with local svf file

I have the following problem with the Autodesk API - viewer.

When I read a file with an urn, I can get data such as refPointTransform.

But when I load a local svf file, I can't.

Here is a photo with an urn: enter image description here

As you can see, there is refPointTransform.

And a photo of a local svf file.

enter image description here

And there is no refPointTransform.

Do you know why? Have I done something wrong?

Solution

  • Happy new year! I got the comments from engineer team: If the user never modifies the "Site Location" in the Revit model, it does not export such a property. Only after the user has specified the "Site Location" in the Revit model (through "Location Weather and Site" dialog in Revit), would this property be exported. And since 2018, user can do this by importing a geo-referenced DWG/RVT as a link and then acquire the location from the link.

    As mentioned in my comments at the beginning, I can only find the model with/without such property (both with on-line urn or offline SVF). I did not see a model that has such property with on-line urn, but not with offline SVF. Could you send me a test file at [email protected]? Thank you!
