Combine two scane.

I have two blender files.
I whant one file.
How I may to add one to another - Did I need to press shift+F1 thousends times???

You can select multiple entities with right mouse button (A selects all). Then click load library.

also, in the original file, if you put all the objects into a group (ctrl-G). when importing you can select the group name and all objects in the group will be imported.
I believe this to be the cleanest method, requiring you to only remember one name (the group name), as opposed to scads of whatever you named your objects.

THanks it work!
