View and Data API tips:conversion between DbId and node

by Daniel Du

In View and Data client side APIs, the assets in the Autodesk Viewer has an object tree, a tree structure that represents The model hierarchy. Each element in the model can be representing as a node of model tree. Each node have a dbId, this is a unique ID for the element in the model. There is a one-to-one correspondence between a node and a dbId.

In View and Data client APIs, some methods use DbId as parameter and some methods with node as parameter, in this case you w Ill need to do the conversion. To get the node object from DbId, this is code snippet:

var node = viewer.model.getData ()     . Instancetree.dbidtonode[dbid];

To get dbId of a node, just with the DbId property:

var dbId = Node.dbid

Just a small tip in case you don ' t know.
