Hey @Ami_Nigam ,

In order to access the geometry inside Dynamo, you need to follow the path of the meshes from Speckle. You can either use Speckle’s web application or Dynamo to investigate. In your case, meshes are stored in 3 level nested layers.

When received in Dynamo, Speckle data is converted into dictionaries. They behave like any other dictionary. You can access the values using key-value notation. Either use Dictionary.ValueAtKey node or use Code Block.
