Anyone as a guidance on how to see a draped image on a TIN surface using Autodesk Forge Viewer (today APS)?
Thanks

We are having an issue with some Inventor models, where the orientation and up direction in the forge viewer does not match the home view within Inventor.
This screenshot is of a sample model in Inventor (home view):
cylinder pointing upwards
This screenshot shows how it is displayed in the viewer:
cylinder on it's side
We are creating the svf file directly from Inventor design automation, in exactly the same way as the forge configurator sample https://github.com/Autodesk-Forge/forge-configurator-inventor
Is there anything that we need to do explicitly to have the viewer use the home view and up direction from the Inventor model?
I think I have now found the answer to my own question!
In the svf exporter I had turned off the option to export file properties:
oOptions.set_Value("ExportFileProperties", false);
Thinking that this would just eliminate the part properties, but it seems like it must remove the up direction and home view also.
Trying to set the anti-aliasing property in autodesk forge (for 2D model/floor plan)
I have adding custom text geometry in my forge viewer but strigling to imrove it's quality.
Tried setQualityLevel (viewer3d.setQualityLevel(true, true)) to set the anti-aliasing on but it didn't improved the qulity/ or anti-aliasing does not seems to be working?
Attaching both images below.

Thanks
I have checked the implementation of Forge viewer and captured some more screenshots to explain the problem again.This time I am capturing geometry created by the autodesk forge measurement tool so that we can target the real problem.
In Autodesk 3d viewer we have this option to enable disable the anti-aliasing
enter image description here
if we set it to on the result is below one.
enter image description here
We can see edges are still jagged but not as compared to what results if we set it to off.
Following is the result of anti-aliasing
enter image description here
Observe the red line and difference that anti-aliasing flag makes in the overall quality of the rendered data.
We need to solve the same problem in 2D version of viewer but unfortunately the option to toggle anti-aliasing is not present in 2D forge viewer.I know that the implementation of anti-aliasing present in Autodesk Forge is FXAA and not sure if there are any limitations for 2d in it? if not then can you please let us know if we can expect this future version of Autodesk forge ? Please let us know
Please note that according to the API reference the antialiasing is:
Not applicable to 2D.
That is most likely why the settings have no effect on your 2D drawing.
I want to add hotspot sphere to a 3D .nwd model which has to be viewed in Autodesk Forge Viewer. Please suggest how hotspot can be added to .nwd naviseworks file.
There are a couple of ways to add hotspots to a model in Forge Viewer:
by adding custom "point clouds" into the scene: https://forge.autodesk.com/blog/3d-markup-icons-and-info-card
by adding custom 3D geometry: https://forge.autodesk.com/en/docs/viewer/v7/developers_guide/advanced_options/custom-geometry/
by overlaying the 3D viewport with HTML elements; the Forge Digital Twin sample code shows how you can compute 2D positions from Forge model coordinates, specifically in the IssueExtension
I have added some materials to a couple of the rooms in my Revit model which seems to end up displaying pure green color (no "Office" text) when the file is uploaded to the Forge Viewer. Is this a familiar matter?
Here are the images for reference:
Revit
Forge
Kind regards,
As Zhong Wu, as of now (Jan/2018) this is not supported: the translation will not understand materials from custom images.
Is it possible to get the real world coordinates form the original model in the Forge viewer? It looks like when a model is loaded into the Viewer it is placed with the center of the model in the origin of the Viewer.
viewer.model.getData().globalOffset is what you are looking for:
Aligning Coordinate Systems in Autodesk Forge Viewer
Afaik, the Forge viewer centres the model. In other words, the origin of the viewer coordinate system is the centroid of the model. The scale of the model remains unchanged. As a result, you can transform the original model coordinates to Forge viewer and vice versa simply by adding or subtracting the model centroid.
