In the “Settings” section, we can adjust some special import options.
The settings of the “Exclude” group let us exclude objects from import by a certain class. Quick default options exclude splines, frozen and hidden objects, and cameras.
In the “Model Merge Options” menu, we can specify to convert our model into a Proxy when merging. We can also choose to import our model as an xRef file.
