Hello all!
I'm wondering what does ''Merge'' the structure mean and why we need to merge our design and when?
In some cases, I make my design flatten merged then I exported GDS file, I got an empty gds file? Why information are lost when exporting?

This is not normal. You must have made a mistake. Show in more detail what you did.

I just selected all the structure then i choose Edit>component> Flatten then Edit>Merge
then when i exported GDS file there are no geometric information
 

As said: this is not the normal behaviour.
It is difficult to help you without going to your specific case. Upload your workspace and/or show screenshots.

i worked on the LTCC Balun (I found on ADS examples)

Then, i got a GDS file when i convert it to GDT file it doesnt contain any geometric info

then i exported to GDS, the export is done successfully bu this message appears

The export is NOT successful. The message says that the AEL code (artwork macro function) for drawing is missing. It seems that this is "coded" layout, not drawn, and you see some cached layout on screen. If the drawing code isn't there, exploding that layout fails, and your layout is empty.

I don't know how you broke this, but with the sample LTCC example in my ADS2016 installation, it works perfectly fine: flatten > merge > GDSII and the resulting layout is fine.

I redo the same steps 3 times: Select the structure> Flatten>Merge then export to GDSII file always the same problem. I don't know where is the problem! can you send me the workspace of the LTCC Balun to test it maybe i changed something on LAyout

You can get it from the ADS main window: File > Open > Example ... and then look in the FEM directory.
