如何显示选定的Autodesk Viewer节点的标签信息？

Question

I want to display a label with detailed information for a selected component from auto desk viewer. Any client side coding available?

Answer 1

Looks to me the simplest way to achieve this is to show the built-in property panel upon clicking an component:

viewer.addEventListener( Autodesk.Viewing.SELECTION_CHANGED_EVENT, event=>{
     viewer.getPropertyPanel(true).setVisible(true)
})

If you'd like to customize a bit then you can retrieve the properties for a given dbid (which identifies a component) and display them in a panel (see how to create custom panels here ):

let dbIdArray = viewer.getSelection(); // obtain ids of selected nodes
model.getBulkProperties(dbIdArray, null, props=>{
   // do stuff with properties here
}) // retrieve properties for an array of nodes

//alternatively retrieve properties for a single node
viewer.getProperties(dbId, props=>{
  // do stuff with properties here
})

See doc for getBulkProperties here and relevant samples here and here

And remember to add reactivity to user selection you can subscribe to the SELECTION_CHANGED_EVENT event.
