如何在 Autodesk Forge Viewer 中添加热点球体？

Question

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.

Answer 1

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
