Unwanted graphics in my combined file

[hung4702]

I have 62 autocad pdf files to combine. I'd get 2 weird boxes added on the 1st page in the right hand top corner. If less than 50, it comes out perfect. Any help would be appreciated.

@hung4702 Honestly, I would look into Autocad to see where the issue lies. If it's always happening top right-hand corner, maybe it's a font issue while you make it into a PDF. Is there hidden text boxes in your 'autocad file'?

i've checked all the layers & entities with missing font. It would NOT show up when I do less than 50. Very strange.

I'm afraid without the file itself to analyze this is pure guesswork.

this morning, I let autocad generated 1 single file of all 66 drawings and it came perfect. Voila! no unwanted boxes. Thanks all.
