The properties of a model can be individually adjusted in the model dialog. It can be opened with a double-click on a model icon in the scene hierarchy:
[Model icon in the scene hierarchy]
Select model thumbnail: when saving a model, a dialog pops open asking for a model thumbnail (that will be displayed in the model browser). If however you wish to save a thumbnail of your model in a different configuration (e.g. you wish to save a model of a snake robot in straight configuration, but you want the thumbnail to visualize the snake robot in a bent configuration), then you can specify the thumbnail here.
Override properties: here you can disable (override) specific properties for the whole model (i.e. for all objects in the model hierarchy tree). This is convenient to quickly disable a model that takes too much calculation time for instance. See also the sections on collidable objects, measurable objects, renderable objects, cuttable objects and detectable objects, and the sim.setModelProperty API function.
Model content acknowledgments/Info: information related to a model. It is always good practice to acknowledge the original author of a model, or imported mesh. When a model that contains acknowledgment information is opened, it will automatically display that information.
