The correct way to export and send a layout (for example email a layout to another computer, user) is as follows.
1. When the layout is completed, go to FILE in ECDESIGN and select EXPORT PROJECT.
2. Save the ZIP file on your computer.
3 Now you can send the file. The zip file will include the Ecdesign (ecd) file and any custom textures, images used.
By using the export, you ensure that the layout will be correct and the user will also be able to see any custom textures/ materials used in the floor plan.
