Thanks

but what if I want to view all the content in 3d, not 1d. Do i need to go through the whole process again?

Hi Nan Sun,
are you sure you got selected model in 1Ds view (left panel)?
To select the model you need to change 2Ds to 1Ds view, expand Component node and click on your model. If there is no model, open .rcproj file in the Notepad (or some other text editor) and check if there is Model node in the XML structure.
