I am not that expert on idd. Here he issue, I can't export my file from idd to pdf, it showing from the background task Failed. See Alert.
on my files i copy paste some vector files from AI and directly paste in idd.. is there any limits on pasting vectors or EPS files on idd?
Any comments or advise is much appreciated.
With InDesign or Illustrator you should not use EPS at all, but this is not the problem here.
Copy and Paste will work without a font and what happens depends on the settings of your preferences. Only with very simple paths without transparency you should use it, like a formed frame which is easier to create in Illustrator than in InDesign.
But normally you should save your file as AI or PDF/X-4 in Illustrator and import it as a linked (not embedded) file into InDesign via File > Place…
