Save Selected
File > Save Selected...
Description:
The Save Selected command (File >
Save Selected...) allows you to save only the currently selected
objects. If you are in a mode other than object mode, it will save all
shapes which are currently editable (and have therefore been selected
while in object mode). A dialog will open to allow you to choose a
name, directory, and file type for the file.
Notes:
-Supported file types are: *.sia, *.obj, *.3ds, and *.dxf.
