In addition to using the on the , you can import geometry by dragging and dropping. If the scene to which you’re importing already contains geometry, 3ds Max Design usually asks whether you want to merge the imported geometry with the existing scene, or replace the scene entirely.
You can import geometry by dragging from a file browser into a 3ds Max Design viewport. When you use this method, typically 3ds Max Design does not prompt you to merge or replace the scene, but merges the imported geometry with what is already there.
When you use the to import geometry into a scene that already contains geometry, in most cases 3ds Max Design opens a dialog that asks whether you want the imported geometry to be added to the scene, or to replace the scene entirely.
In general, once you respond to this dialog, a second dialog with geometry-specific options is displayed, as described in the topics that follow. (For some geometry formats, only one dialog appears, and these options are merged with the geometry-specific options.)
