How to import multiple files one window

I want to open two files in the same window so i can part them together to create one design. Ive tried a few ways but my noobee is strong. L0l please help. Thank you for help

Use Import to load into an existing design.

Open one file, select all (Ctrl+a)
Copy (Ctrl-C)

Close file #1

Open second file
Paste from clipboard (Ctrl+V)

Do your thing… Then save. (Ctrl+s)

Edited - thanks for checking my work!

The copy step is missing here :wink:
